| vilobhmm1 | the whole reason for introducing the start() and leave() interface was that in the tooz driver that I have introduced I use start() for start/initialization and join() for joining the group for clear speration of functionality you can see here https://review.openstack.org/#/c/172502/4/nova/servicegroup/drivers/tz.py . In your feedback you mentioned that you dont want to introduce few more interfaces to nova/servicegroup/ | 00:06 |

| sudipto | PaulMurray, sorry had stepped out for a bit. I wanted to implement something like a memory b/w utilization as a RT plugin. | 10:56 |
| sudipto | PaulMurray, I have implemented it using the monitors currently - but that would mean that the data is populated in the metrics column and is available to the host_states on the controller. | 10:56 |
| sudipto | PaulMurray, hence essentially it doesn't use the RT. | 10:57 |
| sudipto | PaulMurray, would you have a suggestion on which framework fits better for this - the monitors or the RT? | 10:58 |
| *** fawadk has quit IRC | 10:58 | |
| *** deepthi has quit IRC | 10:59 | |
| PaulMurray | sudipto, RT deals with values that are accounted - generally they are artificial values, like disk space or memory that are added up form the number of instances and their nominal usage. These values may also translate into limits on actual usage in the hypervisor but not necessarily. | 11:01 |
| sudipto | PaulMurray, I wouldn't want to tie this with the extra specs of instances. | 11:01 |
| PaulMurray | sudipto, metrics are used to monitor actual use of resources | 11:01 |
| sudipto | PaulMurray, So metrics sounds like the right place for this.... | 11:01 |
| *** jistr has quit IRC | 11:02 | |
| *** nihilifer has quit IRC | 11:03 | |
| PaulMurray | sudipto, so if you want to monitor the current use of memory b/w on the host, as opposed to saying "count 5 for this flavor" then metrics sounds like it | 11:03 |
| *** nihilifer has joined #openstack-nova | 11:03 | |
| sudipto | PaulMurray, hmm yeah - and then nothing should theoretically stop us from writing a filter that would just use this right? Something on the lines of this spec: https://review.openstack.org/#/c/154423/5/specs/liberty/approved/cache-aware-weigher.rst | 11:04 |
| sudipto | PaulMurray, would this just require an implementation then or a spec per your advice? | 11:04 |
| *** jistr has joined #openstack-nova | 11:04 | |
| *** tojuvone has quit IRC | 11:07 | |
| PaulMurray | sudipto, I think you can probably just do it. These are simple plugins, so specs seems heavy weight - the filter would be quicker and easier to write than the spec. | 11:08 |
| PaulMurray | sudipto, Do it and see if anyone complains | 11:08 |
| sudipto | PaulMurray, Ok sounds good. Thanks Paul. | 11:09 |
| *** fawadkhaliq has quit IRC | 11:09 | |

| PaulMurray | sudipto, do a BP - it can be approved without a spec if its trivial. You need to set the target and then you can put your patches up referring to that bp | 11:16 |

| tojuvone | VW_ so last version of BP is to mark service (nova-compute) down. The idea of whole is that external system can detect host failed fast and report to Nova to change all related states fast. | 14:21 |
| dansmith | alex_xu: are you still around? | 14:21 |
| tojuvone | Also fencinf would be guaranteed. No scheduling for that host and evacuate coudl happen immediately | 14:22 |
| VW_ | ah, yes tojuvone - I remember this one now. I'm fine if something changes the compute state, but I'd agree with johnthetubaguy that doesn't always mean the instances are down as well | 14:23 |
| VW_ | so I'd be leery to automatically change all states | 14:23 |
| tojuvone | As single API for host couldn't be solution to mark nova-compute and VMs to down/error, there is currently only this one BP for nova-compute | 14:23 |
| tojuvone | now it would be to make more BPs. | 14:23 |
| tojuvone | Yes, that is why everybody interested of HA would even currently have own monitoring... | 14:24 |
| tojuvone | now it would be to have API if the monitoring can know or if it can fence (power down) | 14:25 |
| VW_ | well, it's a little more that that. I think nova computes should be completely expendable. We actually run them as a VM on the host - which means the compute can die and the host and instances are just fine. | 14:25 |
| *** jistr|mtg is now known as jistr | 14:26 | |
| tojuvone | So not solution for all cases | 14:26 |
| VW_ | but anyway, I like the idea of the system quickly knowing a compute (or underlying host) is down and disabling the compute | 14:26 |
| *** atuvenie has joined #openstack-nova | 14:27 | |
| tojuvone | Yes and like I am now working also with this opensource project Doctor in OPNFV, that should have Telco (NFV) capability to detect host faults and fence... | 14:27 |
| tojuvone | So when that shoudl be ready there should be infra tool for everybody to use | 14:28 |

| tojuvone | Ok. The OPNFV Doctor link is in the spec to have some Telco perspective, but really any HA interested would want all those VM and nova-compute states fast and reliably (meaning VMs are surely down if nova-compute marked down).

| openstack | Launchpad bug 1223345 in OpenStack Compute (nova) "Soft-deleted instance files deleted by periodic cleanup task" [High,Fix released] - Assigned to Hans Lindgren (hanlind) | 15:39 |
| mordred | why is it that someone wouldn' want soft-deleted instanaces cleaned up? | 15:39 |
| mordred | and/or what if someone _did_ want soft-deletes to just diaf | 15:39 |
| dansmith | mordred: because soft-deleted instances are supposed to be undeletable | 15:39 |
| mordred | aroo? | 15:39 |
| dansmith | johnthetubaguy: I guess the rest of the ones up there are important, and not worth reverting anything already merged | 15:40 |
| mordred | dansmith: can I translate that to mean "it is the intent of nova to keep soft-deleted rows in the database until the end of time" ? | 15:40 |
| dansmith | mordred: there is a "restore instance" call that undeletes a thing | 15:40 |
| mordred | ah | 15:40 |
| *** amotoki has quit IRC | 15:41 | |
| dansmith | mordred: well, I think in the case of soft-deleted instances there is an interval for which they're still available, IIRC, but I don't really know | 15:41 |
| *** andreykurilin__ has joined #openstack-nova | 15:41 | |
| dansmith | mordred: but as you know, nova has a confused relationship with deleted things | 15:41 |
| mordred | it just seems that with a cleanup thread, having a longer undelete-available interval would be friendlier to operators | 15:41 |
| mordred | dansmith: well, I'm learning this | 15:41 |
| *** kaisers has quit IRC | 15:41 | |
| mordred | dansmith: I don't really think I fully grokked the extent of the confusing relationship | 15:41 |
| ttx | johnthetubaguy: we shouldn't have merged that one ? | 15:41 |
| ttx | johnthetubaguy: is it the bug is invalid or the fix in invalid ? | 15:42 |
| dansmith | mordred: we have soft delete of instances, plus soft-delete of rows, plus shadow tables, plus zero ability to define when something can be moved from soft-deleted to shadow without breaking things | 15:42 |
| dansmith | mordred: (AFAIK) | 15:42 |
| mordred | dansmith: that's so exciting | 15:42 |
| clarkb | mordred: dansmith is there a way as a user to indicate when deleting an instance that i neverwant to be able to restore the instance so just really delete it? | 15:43 |
| johnthetubaguy | ttx: not sure at this point, just checking in general with other folks and if they are happy with all the ones we backported | 15:43 |
| dansmith | mordred: it's like russian roulette.. with your production DB :) | 15:43 |
| *** amotoki has joined #openstack-nova | 15:43 | |
| *** amotoki has quit IRC | 15:43 | |
| dansmith | clarkb: soft delete is different than delete from a user perspective I think | 15:43 |
| johnthetubaguy | dansmith: thanks for checking that lift for me, they all seemed worth backporting | 15:43 |
| dansmith | clarkb: i.e. delete means "I don't want to maybe undelete" | 15:43 |
| mriedem | there is a command to move deleted rows to shadow tables http://git.openstack.org/cgit/openstack/nova/tree/nova/cmd/manage.py#n920 | 15:44 |
| openstackgerrit | Doug Hellmann proposed openstack/python-novaclient: Update README to work with release tools https://review.openstack.org/175947 | 15:44 |
| ttx | johnthetubaguy: looks like it was originally proposed for release by a "Dan Smith". Probably an alias. | 15:44 |
| mriedem | but that doesn't 'delete' things | 15:44 |
| clarkb | dansmith: I don't think that is what we are experiencing | 15:44 |
| dansmith | ttx: some of the proposed things were good, others I think needed some discussion | 15:44 |
| clarkb | but mordred has actual details | 15:44 |
| dansmith | ttx: not worth it at this point | 15:44 |
| mordred | I don't suppose there is an option which says "just perform the SQL delete and don't do soft-deletes or shadowtables kthxbia" is there? | 15:44 |
| dansmith | mordred: nope | 15:45 |
| dansmith | mordred: we never actually delete anything ever | 15:45 |
| dansmith | mordred: the closest is moving something from real to shadow tables | 15:45 |
| dansmith | mordred: except for a few cases of smaller things, but nothing you have visibility to I tink | 15:45 |
| ttx | dansmith, johnthetubaguy: ok well, keep me posted | 15:45 |
| mordred | dansmith: well - I mean - infra creates and deletes 20k instances a day on our clouds | 15:45 |
| dansmith | mordred: clarkb: just in defense of everyone where, this has been the case since the dawn of time, in case it's not clear :) | 15:46 |
| mordred | dansmith: so we wind up producing HUGE amounts of data in those tables over time | 15:46 |
| johnthetubaguy | mordred: we actually go and delete those records after a month now | 15:46 |
| dansmith | mordred: right, actual cleaning of the DB is left as "an exercise for the operator" :/ | 15:46 |
| mordred | dansmith: that's so friendly | 15:46 |
| johnthetubaguy | mordred: and yes, the tables got very large | 15:46 |
| dansmith | mordred: see ^ :) | 15:46 |
| mordred | johnthetubaguy: but by we - you mean rackspace, not nova? | 15:46 |
| dansmith | yes, that's what he means | 15:46 |
| dansmith | my "we" is nova, his "we" is actual people | 15:47 |
| johnthetubaguy | mordred: yeah, sorry, I mean public cloud at rackspace in that case, different hat on there for a moment | 15:47 |
| mordred | johnthetubaguy: if both of the public cloud providers are now deleting the rows on a cronjob - why not add an option to nova.conf to have the cleanup thread delete rows when it runs? | 15:47 |

| dansmith | johnthetubaguy: heh | 15:47 |
| mordred | I mean, it seems like nova is already doing that sort of thing - cleaning up after itself would be a friendly thing for the operators | 15:47 |
| dansmith | we[0] == rax, w[1] == nova | 15:47 |
| mordred | dansmith: :) | 15:48 |
| johnthetubaguy | lol | 15:48 |
| dansmith | mordred: well, part of the problem is, it's dangerous and hard to actually know when it's okay in some cases | 15:48 |
| dansmith | mordred: so we shift the risk to the operators | 15:48 |
| mordred | dansmith: that seems like a bug | 15:48 |
| dansmith | mordred: I don't really disagree :) | 15:48 |
| mordred | :) | 15:48 |
| dansmith | mordred: now that we have flavors separated from instances, we could get a lot closer | 15:49 |
| johnthetubaguy | mordred: for context, turns out we updated our script so it doesn't delete so fast if it sees the read slaves lagging behind the master too log, sigh, turns out its deployment specific, but I should get that uploaded somewhere public | 15:49 |

| mriedem | sorry | 15:53 |
| johnthetubaguy | mordred: best bit, it doesn't work | 15:53 |
| mordred | thing two is I'm going to finish that spec that was just linked because nova should clean after itself | 15:53 |
| dansmith | the quota stuff is problematic, I think that's well known | 15:53 |
| mordred | thing three is that I'm going to delete all foreign keys with prejudice because they're stupid and not giving any value | 15:53 |
| *** baoli_ has joined #openstack-nova | 15:53 | |
| bauzas | mordred: be happy, we just removed one | 15:54 |
| mriedem | given we don't cascade anything on the FKeys i'd agree with that | 15:54 |
| mordred | bauzas: yay! | 15:54 |
| mordred | mriedem: I know of literally zero large-scale mysql sites that use them | 15:54 |

| sdague | mordred: they all emulate it in the application? | 15:54 |
| mordred | sdague: yup | 15:54 |
| mordred | sdague: it's too costly to do them in teh db | 15:55 |
| mordred | the db is the hardest scaling point to have things centralized | 15:55 |
| *** atuvenie_ has joined #openstack-nova | 15:55 | |

| *** ijw has quit IRC | 15:55 | |
| mordred | same reason using stored procedures is a nono in large deployments | 15:55 |

| dansmith | with our objects facade we have a good place to do that emulation | 15:55 |
| dansmith | as we do for flavors now | 15:55 |
| mordred | sdague: but you don't need it enforced by the engine | 15:55 |
| mordred | you just want the relational algebra | 15:55 |
| *** ijw has joined #openstack-nova | 15:55 | |

| *** dboik has quit IRC | 15:56 | |

| *** sileht has joined #openstack-nova | 15:57 | |
| dansmith | sdague: yeah | 15:57 |

| *** dboik has quit IRC | 15:58 | |
| *** dboik has joined #openstack-nova | 15:58 | |
| artom | mordred, the bit that mriedem linked though, http://git.openstack.org/cgit/openstack/nova/tree/nova/cmd/manage.py#n920 | 15:58 |
| dansmith | sdague: probably lots. IPs, networks, | 15:58 |
| dansmith | sdague: I could pull up the model if you want, but there are things | 15:58 |
| artom | That + something that empties out the shadow tables == a really ugly delete, no? | 15:58 |
| *** armax has left #openstack-nova | 15:58 | |
| *** Sukhdev has joined #openstack-nova | 15:58 | |
| sdague | yeh, ips and networks seem a little trickier | 15:59 |
| dansmith | yeah | 15:59 |
| *** dboik has quit IRC | 15:59 | |
| dansmith | metadata entries | 15:59 |
| *** dboik has joined #openstack-nova | 15:59 | |
| dansmith | actually, most everything | 16:00 |
| dansmith | consoles, dns stuff | 16:00 |
| *** armax has joined #openstack-nova | 16:00 | |
| *** ijw has quit IRC | 16:00 | |
| dansmith | basically you just have to run through almost all models, delete where instance_uuid=$uuid | 16:00 |
| dansmith | then you can delete the real instance | 16:00 |
| dansmith | most things are instance-centric | 16:00 |
| dansmith | so if you delete them before the instance, you're okay | 16:00 |
| dansmith | but there are things the instance depends on | 16:01 |
| sdague | dansmith: shouldn't it be the other way around? | 16:01 |
| *** tsekiyama has joined #openstack-nova | 16:01 | |
| sdague | delete the instance first | 16:01 |
| bauzas | sdague: you can't, FK | 16:01 |
| *** armax has left #openstack-nova | 16:01 | |
| mriedem | right, everything has a fkey on instances.uuid | 16:01 |
| ndipanov | what's the problem with FKs again | 16:01 |
| dansmith | sdague: well, things that are discoverable from the API would hit InstanceNotFound errors if they get listed while you've got the instance deleted | 16:01 |
| ndipanov | I missed that class | 16:01 |
| mriedem | so you have to do what i did in my cleanup script for null instances.uuid | 16:01 |
| *** armax has joined #openstack-nova | 16:02 | |

| bauzas | ndipanov: the problem is at scale how to purge the DB | 16:02 |
| *** Marga_ has joined #openstack-nova | 16:02 | |
| dansmith | sdague: then there are things like the instance->info_cache dependency | 16:02 |
| *** baoli_ has quit IRC | 16:02 | |
| bauzas | ndipanov: and FKs make the cleanup a little harder | 16:02 |
| dansmith | not sure which way that needs to go | 16:02 |
| sdague | right, gotcha | 16:02 |
| ndipanov | bauzas, well for the right reasons | 16:03 |
| ndipanov | so that you don't have to think about that sort of consistency in your app | 16:03 |
| bauzas | ndipanov: here, the question is : should that be abstracted for operators ? | 16:03 |
| *** redbeard has quit IRC | 16:04 | |
| *** atuvenie_ has quit IRC | 16:04 | |
| bauzas | ndipanov: atm, this is a DIY stuff | 16:04 |
| *** baoli has joined #openstack-nova | 16:04 | |
| ndipanov | bauzas, abstracted as - something like shadow-tables so taht you can clean things up but that doesn't suck? | 16:04 |
| bauzas | ndipanov: abstracted like - I want to ask Nova to really delete my deleted instances forever | 16:05 |
| *** sahid has joined #openstack-nova | 16:05 | |
| bauzas | I'm just a little concerned about all the locks we could get on the tables, wrt all the FKs we have :) | 16:06 |
| dansmith | can someone +W this please? | 16:06 |
| dansmith | https://review.openstack.org/#/c/175890/2 | 16:06 |
| bauzas | it's like "push the button and we freeze all the tables to your convenience" | 16:06 |
| *** pixelb has joined #openstack-nova | 16:06 | |
| artom | Pfft, the real solution is to get Western Digital to sponsor OpenStack and ship a free disk or two to all operators. | 16:06 |
| dansmith | johnthetubaguy: that's a bug, but probably not worth putting in RC2 and just backporting, but I'll let you decide | 16:06 |
| *** ildikov has quit IRC | 16:06 | |
| mordred | ndipanov: anything that is for the reason "so you don't have to think about the consistency in your app" is a mistake | 16:07 |
| mordred | because the app's job is to think about the consistency | 16:07 |
| mordred | and there is a model class | 16:07 |
| mordred | that encapsulates that | 16:07 |
| ndipanov | mordred, well why use relational dbs then | 16:07 |
| mordred | that the logic about how to perform basic tasks is split across two places and almost nobody understands how to safely perform a task like "delete teh instance records" is a clear indication that the theory is not working | 16:07 |
| mordred | ndipanov: because there are HUGE benefits to the data model | 16:08 |
| dansmith | mordred: probably worth noting that you're talking about using them at crazy scale, because the point of the constraints is defining what you want the DB to enforce for you in a normal case | 16:08 |
| mordred | ndipanov: you don't need db level enforcement of the foreign keys to reap them | 16:08 |
| *** ijw has joined #openstack-nova | 16:08 | |
| mordred | dansmith: yes | 16:08 |
| mordred | this is why defining them in the sqlalchemy model is a GREAT idea | 16:08 |
| mordred | actually applying them at the db level is the thing that does not scale and provides no benefit | 16:08 |
| ndipanov | mordred, k - in that case I'd say we should look at whether our data model is sane for how we use it vs. blanket kill FKs | 16:08 |
| dansmith | ndipanov: thought you knew, mordred has two settings: "off" and "kill with fire" | 16:09 |
| mordred | ndipanov: well, there are zero cases in which a production database should actually have FKs applied to it - but I agree, working on the data model is actually the important task - not fighting with me about megascale database things :) | 16:09 |
| bauzas | yay, let's denormalize stuff ! | 16:09 |
| *** atuvenie_ has joined #openstack-nova | 16:10 | |
| mordred | well | 16:10 |
| mordred | we having the good table and relationships == good | 16:10 |
| mordred | having some summary tables (materialized views) == performance optimization, also good | 16:10 |
| ndipanov | agreed | 16:10 |
| *** ijw_ has joined #openstack-nova | 16:11 | |
| bauzas | +1 | 16:11 |
| *** moshele has quit IRC | 16:11 | |
| *** dsanders has joined #openstack-nova | 16:11 | |
| mordred | quotas, for instance, should be being run on a rollup/summary table rather than directly on the underlying information tables | 16:11 |
| mordred | because you can get actual atomic update operations that way | 16:11 |
| mordred | and if somethign goes wrong, you can always rebuild the summary table from the base data | 16:12 |
| ndipanov | I don't know - I get the argument that with fk's your encoding logic into your db schema and in your app | 16:12 |
| artom | mordred, isn't it the RDBMS's job to ensure atomicity? | 16:12 |
| mordred | so no need for locking _at_ _all_ and blinding fast speed and at least as semantically correct as current | 16:12 |
| mordred | artom: only if you want to write academic papers | 16:12 |
| *** ijw has quit IRC | 16:12 | |
| ndipanov | I just can't help but think that killing them you trade one class of bugs for another | 16:12 |
| mordred | ndipanov: put them in teh app model - awesome | 16:13 |
| artom | mordred, why is it bad in real life? | 16:13 |
| mordred | artom: because they are a scaling bottleneck | 16:13 |
| artom | Ah, that's a different thing | 16:13 |
| mordred | and if your app doesn't understand the object model you're screwed anyway | 16:13 |
| mordred | also - once you shard data into more than one db | 16:13 |
| mordred | you can't use them anyway | 16:13 |
| artom | mordred, if you want scale don't chose RDBMs | 16:13 |
| mordred | artom: wrong | 16:13 |
| artom | That's the real problem | 16:13 |
| mordred | artom: categorically untrue | 16:14 |
| bauzas | artom: not really, it's about how you shard your model | 16:14 |
| *** doron is now known as doron_afk | 16:14 | |
| mriedem | mordred: are any other openstack projects using views? | 16:14 |
| mordred | artom: and I will happily point you at facebook adn google as my examples | 16:14 |
| mordred | mriedem: you don't actually want VIEWs | 16:14 |
| openstackgerrit | Dan Smith proposed openstack/nova: Adding user_id handling to keypair index api call https://review.openstack.org/70485 | 16:14 |
| mordred | mriedem: you want app-generated summary tables | 16:14 |
| mordred | views in mysql are not materialized and are a terrible idea in production | 16:14 |
| artom | mordred, I know Facebook uses MySQL, don't know how they scale it though. | 16:14 |
| mordred | artom: I do :) | 16:14 |
| artom | mordred, didn't know Google used MySQL at any sort of scale. | 16:15 |
| artom | mordred, well, how? :) | 16:15 |
| mordred | artom: the main money maker for google, adsense, runs 100% on mysql | 16:15 |
| ndipanov | so once you get rid of the FKs, you also say I won't use a number of feature given to me by MCC your db implements and you have to be careful about thos in your code too | 16:15 |
| mordred | artom: sharding | 16:15 |
| mordred | ndipanov: yes | 16:15 |
| ndipanov | sometimes that's OK | 16:15 |
| mordred | but you have to be careful in your code _Anyway) | 16:15 |
| ndipanov | but sometimes you open yourself to ugly race conditions | 16:15 |
| mordred | sure | 16:15 |
| ndipanov | right that;s true | 16:15 |
| mordred | main thing is - the db - rdbms or not, is not a magic wand | 16:16 |
| mordred | it's not going to design an app for yoy | 16:16 |
| artom | mordred, and in what way sharding prevents FKs/atomicity? | 16:16 |
| ndipanov | yes true | 16:16 |
| mordred | artom: FKs don't work across servers | 16:16 |
| mordred | artom: when part of your model is on one server and part is on another server, you MUST handle the logic in your code | 16:16 |
| artom | mordred, wait, model? | 16:16 |
| bauzas | artom: usually, you want to shard per col | 16:17 |
| bauzas | artom: and not per row | 16:17 |
| mordred | artom: yes. say you have your instances split across 10 servers - and there isa whole other server for flavors | 16:17 |
| artom | bauzas, ah! | 16:17 |
| mordred | bauzas: you might want to do both | 16:17 |
| *** beagles_brb is now known as beagles | 16:17 | |
| mordred | sharding by row is known as horizontal sharding, sharding by column as vertical | 16:17 |
| bauzas | mordred: yay, was just giving the reason why it doesn't work :) | 16:17 |
| artom | But then haven't you basically recreated a key-value store in SQL? | 16:17 |
| mordred | and big places tend to use a combination of both | 16:17 |
| mordred | bauzas: :) | 16:17 |
| mordred | artom: nope | 16:18 |
| artom | Since all the logic is in the code anyways? | 16:18 |
| *** romainh has left #openstack-nova | 16:18 | |
| mordred | artom: because on a per-server basis you still get the benefits of indexes and joins | 16:18 |
| bauzas | artom: that's just trade-off | 16:18 |
| mordred | artom: so what you have is sharded indexing | 16:18 |
| bauzas | +1 | 16:18 |
| *** fawadkhaliq has quit IRC | 16:18 | |
| mordred | and properly design indexes and joins are super useful | 16:18 |
| artom | Key-value stores tend to have indeces (or equivalents), no? | 16:19 |
| mordred | they're getting there | 16:19 |
| bauzas | artom: in general, you shard wrt your model to make joins locally | 16:19 |
| *** doron_afk has quit IRC | 16:19 | |
| mordred | and key/value stores are useful in some cases | 16:19 |
| bauzas | artom: that would speed up local joins while your app can still scale | 16:19 |
| mordred | yup | 16:19 |
| mordred | artom: often times people will use a key-value layer on top of the rdbms layer as a smart-cache | 16:20 |
| *** fawadkhaliq has joined #openstack-nova | 16:20 | |
| mordred | so instead of making a summary table | 16:20 |
| mordred | you make a key-value entry with the summary in the blob | 16:20 |
| *** iamjarvo has quit IRC | 16:20 | |
| mordred | but you also but the main data into the rdbms | 16:20 |
| mordred | so that you don't have to care about the data longevity in the key-value | 16:20 |
| mordred | since most of them do not have the production usage to be at the point of knowing their failure domains well enough to trust them as the ultimate store of all of your things | 16:21 |
| mordred | there isn't a single right answer for any of this - other tahn FKs being bong :) | 16:21 |

| *** vilobhmm1 has quit IRC | 16:24 | |
| artom | (Thanks for the answers though, I've learned) | 16:24 |
| mriedem | push a patch with the db migration that does it, run it through check to see if there are bugs | 16:24 |
| bauzas | mriedem: agreed, I think it's doable | 16:25 |
| bauzas | artom: I made the move for the service/compute FK and that was really not an issue | 16:25 |
| mriedem | yeah i don't really see a problem with it since the FKeys don't do anything since they don't cascade anything | 16:25 |
| artom | Maybe nothing currently existing will break, but I feel like that's opening up a whole slew of new bugs as ndipanov said. | 16:26 |
| bauzas | artom: the main problem I had was that I was providing a new column for doing the denormalization and *that* was the problem | 16:26 |
| ndipanov | so a quick search on google seems to imply taht innodb should not have a massive overhead on locking for FKs | 16:26 |
| mriedem | artom: but we can still orphan deleted stuff with fkeys today since we don't have ondelete=cascade | 16:26 |
| ndipanov | iow - if there is massive locking caused by FKs - your model or queries are likely wrong | 16:27 |
| bauzas | ndipanov: I can ask some peers I know about that, but I think it's not really a black-or-white answer | 16:27 |

| bauzas | ndipanov: like table A and table B have relationships, but both can be written for good reasons | 16:30 |
| ndipanov | bauzas, so as an example - if most of your modifications include something that will lock the related table | 16:30 |
| ndipanov | then that field should not be a FK for sure | 16:30 |
| bauzas | I see | 16:31 |
| artom | mriedem, so there's no cascade... then FKs are currently used just to... enforce relational integrity? | 16:31 |
| *** tojuvone has quit IRC | 16:31 | |
| ndipanov | otherwise - it seems to me that you get stuff for mostly free | 16:31 |

| ndipanov | thanks! :) | 16:32 |
| ndipanov | what I am not sure about is "nuke FKs" as a remedy :) | 16:33 |
| mordred | zzzeek: he. | 16:33 |
| mordred | zzzeek: I do and always have disagreed with you | 16:33 |
| mordred | but that's ok | 16:33 |
| mordred | zzzeek: FKs in sqlalchemy model == yes | 16:33 |
| mordred | zzzeek: FKs applied to db == silly | 16:34 |
| artom | mordred, wait, you can separate the two? I thought it was pretty much a 1:1 mapping... | 16:34 |
| zzzeek | mordred: it’s nice to know that a DB will never have orphaned records that crash the app | 16:35 |
| zzzeek | artom: theres the notion that the schema has FK-like relationships, then there is the constraint itself | 16:35 |
| *** Mike_D_laptop has joined #openstack-nova | 16:35 | |
| mordred | zzzeek: sure. but for all the reasons listed above, if you depend on the rdbms catching taht for you, you are limiting how well you can scale your app if you need to grow past a single server | 16:35 |
| artom | zzzeek, oh, so pulling an example out of my ass, something like "network_id" in the instances table without actually setting the FK constraint? | 16:36 |
| mordred | zzzeek: which is why you should for sure design as if you had them | 16:36 |
| mordred | zzzeek: and in fact, in dev/test you shoudl apply them to the db | 16:36 |
| zzzeek | mordred: OK there’s a lot in there. “grow past a single server”, that’s a whole ball of wax | 16:36 |

| bauzas | dansmith: re: https://review.openstack.org/#/c/164762/9 I wonder why we couldn't put the logic outside of the object | 16:50 |
| *** mpaolino has joined #openstack-nova | 16:50 | |
| bauzas | dansmith: I saw you were not against the idea of adding a new remotable method for a specific usecase hence my wonders | 16:51 |
| bauzas | dansmith: I don't really like having myspecificmethodformysingleuse() being remotable | 16:52 |
| bauzas | well, I'm not saying having it remotable is bad, just that it makes things worst | 16:52 |
| dansmith | bauzas: well, the less specific it is, the more data we send over rpc just to do the filtering on the other side | 16:53 |
| bauzas | dansmith: agreed, but here the payload is really slow | 16:53 |
| dansmith | bauzas: I agree that adding them for no reason is just debt, but if there's a good reason, it makes sense | 16:54 |
| bauzas | s/slow/small | 16:54 |
| bauzas | dansmith: and like I said, it's just a matter of how many instances we have per group | 16:54 |
| bauzas | see the other https://review.openstack.org/#/c/169489/6/nova/objects/instance_group.py,cm | 16:54 |
| bauzas | dansmith: in 2 patches, we're just adding 2 new remotable methods for just a single usecase that can be done in the same loop | 16:55 |
| dansmith | in this case, I'm not sure doing this outside the remotable is still the same thing | 16:56 |
| bauzas | dansmith: iterating over the list of computes is the same | 16:56 |
| dansmith | you'd have to request all the instances on all hosts that are represented in the group, which could be large for even a small group, right? | 16:56 |
| bauzas | dansmith: so we can do both checks in the same loop | 16:56 |
| bauzas | dansmith: yeah that's O(n) | 16:57 |
| *** harlowja_away is now known as harlowja | 16:57 | |
| bauzas | dansmith: but that sounds a small price to pay IMHO, in particular if 2 methods are doing that | 16:57 |
| bauzas | dansmith: so we can just do the loop once | 16:58 |
| dansmith | but instances are really large | 16:58 |
| dansmith | and also, | 16:58 |
| *** annashen has joined #openstack-nova | 16:59 | |
| bauzas | well, we're getting the list of hosts whose at least one instance is in the server group | 16:59 |
| dansmith | I feel like there is a certain amount of atomicity we may want to have for something like this that we can't guarantee across multiple calls | 16:59 |
| dansmith | granted, the point is that ids are monotonically increasing, but that could be different with a different backend | 17:00 |
| bauzas | dansmith: that's also another concern I didn't raise | 17:00 |
| bauzas | dansmith: because I don't like checking against IDs | 17:00 |
| bauzas | that's just assuming that it won't change | 17:00 |
| bauzas | dansmith: so before commenting saying I was disagreeing, I have to think why it's just all of that needed | 17:01 |
| dansmith | bauzas: right, but the semantics of the call do not imply comparison by id, which means we could change it later without the client needing to know | 17:01 |
| bauzas | like saying that we add an instance in a group before even making sure that instance can be booted seems like a bit optimistic to me | 17:01 |
| dansmith | I don't follow | 17:02 |
| bauzas | sorry | 17:02 |
| bauzas | the problem is that the instances being booted are already part of the group, right ? | 17:02 |
| dansmith | we have to put it into the group/host before we start booting it and then if it fails, we roll back | 17:02 |
| dansmith | no | 17:02 |
| dansmith | it's that the instance is assigned to the host | 17:02 |
| *** vilobhmm1 has joined #openstack-nova | 17:04 | |
| bauzas | dansmith: so the validation call is getting the host, I see | 17:04 |
| *** vilobhmm11 has joined #openstack-nova | 17:04 | |
| *** davideagnello has joined #openstack-nova | 17:04 | |
| bauzas | dansmith: in that case, why not filtering out get_hosts using the instance_uuid ? | 17:04 |
| bauzas | I mean using the exclude arg ? | 17:05 |
| dansmith | sorry, I'm really confused | 17:05 |
| *** Sukhdev has joined #openstack-nova | 17:05 | |
| dansmith | we filter by the uuids in the group | 17:05 |
| bauzas | I think I'm confused too | 17:06 |
| bauzas | okay, before discussing further I need to better understand what the problem is | 17:06 |
| bauzas | because I probably misunderstood | 17:06 |
| davideagnello | hello, I have been trying out Tempest and Rally for integration and scenario testing for stackforge project Cue. Nova has tests in both frameworks, I would like to get some feedback tempest vs. rally, using one or both. | 17:06 |

| sahid | an interesting fix ready to be merged here https://review.openstack.org/#/c/173187/ | 18:03 |
| sahid | mriedem: ^ perhaps you can check it | 18:03 |
| cfriesen | bauzas: dansmith: sorry, didn't see you were discussing my proposed changes. In both cases we could move the logic to nova-compute. Ultimately it would mean calling objects.InstanceList.get_by_filters() and getting all the instances in the group (serializing them and passing them over the wire back to compute manager). The advantage of the new remotable methods is that the RPC response is just one or more hostnames instead | 18:04 |
| cfriesen | of the full object for all instances in the group. | 18:04 |
| dansmith | cfriesen: I'm not sure we were :) | 18:04 |
| mriedem | sahid: has ndipanov seen that change? | 18:04 |

| dansmith | sahid: me too :) | 18:10 |
| cfriesen | dansmith: bauzas: we will only ever do one of the checks...for anti-affinity we need the hosts of all earlier instances, and for affinity we need the host of the earliest instance. | 18:10 |
| *** annegentle has quit IRC | 18:10 | |
| cfriesen | dansmith: bauzas: I suppose one option would be a single remotable function to return the hosts of earlier instances, along with the instance ID of the lowest-id group member running on that host. Then the affinity case could just pick the host with the lowest id number. Seems a little hacky though. | 18:12 |

| artom | Going back to the database delete thing from earlier, what would be the implications of adding a feature that gives operators an option to *actually* delete stuff when it's deleted, not just soft-delete? | 19:39 |
| artom | In that case, the DIY would be "have proper backups" instead of "clean the DB" | 19:40 |
| *** achanda has quit IRC | 19:41 | |
| *** Marga_ has quit IRC | 19:42 | |
| melwitt | artom: well, the way it's supposed to work is operators can run a nova-manage db archive which will delete things with deleted != 0 and move them to the shadow tables, but last I remember the archive tool is broken | 19:44 |
| artom | melwitt, I just tried, it is. | 19:44 |
| artom | And there are other criticisms levied against it, like complexity and slowness. | 19:45 |
| mriedem | i thought zzzeek and/or sdague had a fix for the archive deleted rows thing? | 19:45 |
| melwitt | mriedem: I think the data loss bug got fixed, but archive still can't work completely because sysmeta is never deleted (soft-deleted) or something like that | 19:46 |
| mriedem | oh that super old bug | 19:46 |
| melwitt | yeah :( | 19:46 |
| artom | In my case it was simply FKs errors (hah) | 19:46 |
| melwitt | artom: right. that's because of the sysmeta, that has to also be deleted for the instance row delete to go through | 19:47 |
| *** lpetrut has joined #openstack-nova | 19:47 | |
| alaski | https://review.openstack.org/#/c/109201/ for the system_metadata soft-delete | 19:47 |
| melwitt | there are some patches up about it but they're not ironed out all the way yet | 19:47 |
| artom | Ok, so fixing archive_deleted_rows is definitely an option :) | 19:48 |
| artom | Still, hypothetically speaking (as a backup plan or whatever), could giving operators a config option to do real deletes instead of soft deletes be considered? | 19:50 |

| mriedem | plus, i've already bled out from this morning's shanking | 19:52 |
| melwitt | artom: that, I don't know. I'd imagine it's been debated on the dev mailing list before but I haven't seen any recent discussion. and as mentioned you can propose a spec about it. you can post on the ML to get preliminary feedback before you go all in to the spec | 19:53 |

| clarkb | sc68cal: at least for things like nova floating ip attachment which that fix is for | 21:16 |
| sc68cal | clarkb: no, tempest has tests for intra-tenant connectivity checks | 21:16 |
| sc68cal | it just has to use v4 to ssh into the node currently ;) | 21:17 |
| clarkb | sc68cal: but none of that is ipv6 in the gate | 21:17 |
| clarkb | because cirros doesn't support ipv6 in dropbear iirc | 21:17 |
| clarkb | nor does it have ping6 | 21:17 |
| clarkb | so next step after this is to get a new cirros image that lets us do ^ | 21:17 |
| sc68cal | clarkb: true, and I have a TODO to take a look at how cirros is built, to tweak the makefiles to make that happen | 21:18 |

| vilobhmm1 | while discussing with harlowja we saw this | 23:15 |
| vilobhmm1 | dims : ^^ | 23:15 |
| harlowja | vilobhmm1 thats also sorta an issue for the nova disable command right? | 23:16 |
| harlowja | *mainly for that (i think?) | 23:16 |
| *** markvoelker_ has quit IRC | 23:16 | |
| melwitt | vilobhmm1: what do you mean by store info? the code you link is pulling all services related to the group, then for each checking last heartbeat in memcache to determine up/down | 23:18 |
| vilobhmm1 | melwitt : fetching info is the write word please disregard *store* as its just a fetch call | 23:19 |
| openstackgerrit | Eric Brown proposed openstack/nova: VMware: Don't raise exception on resize of 0 disk https://review.openstack.org/173170 | 23:19 |
| vilobhmm1 | i mean shouldn't the fetch also be from memcache ? like for zk.py it fetches info from the znode tree stored in zookeeper | 23:19 |
| melwitt | vilobhmm1: okay. so there it's getting the list of services from the db, but then for each of those fetching from memcache in the is_up() function | 23:20 |
| melwitt | that is, I think only the heartbeats are stored in memcache, not the services themselves | 23:21 |
| vilobhmm1 | melwitt : seems like that whereas in case of zookeeper driver even the services info is stored in zookeeper; thats not the case in case of memcache driver (ideally it should be so) | 23:29 |

| melwitt | vilobhmm1: yeah, I see your point. if anything I would think zk driver should do similar as the others. I don't have history about why it's different, or whether it does anything to sync state with the nova db, if someone were to update disable/enable | 23:40 |
| vilobhmm1 | melwitt : yep thats the point…the info doesn't seem in sync and which is not good :( | 23:42 |
| dansmith | vilobhmm1: really, no need to ping everyone on the planet with every comment | 23:42 |
| dansmith | vilobhmm1: also, most of nova-manage directly dabbles in the database.. that's kinda the point | 23:42 |
| vilobhmm1 | ok | 23:42 |
| dansmith | vilobhmm1: if it's doing something in the DB that causes it to not work for a different technology, it probably needs to be refactored to use an abstract interface | 23:43 |
| vilobhmm1 | dansmith : so how is the services info sync maintanied in case of zookeeper sg driver | 23:43 |
| vilobhmm1 | sure | 23:44 |
| vilobhmm1 | at present | 23:44 |

| dansmith | vilobhmm1: I don't know, I don't look at that code much. It gets so little attention, that I'm skeptical that much other than the db driver gets really used | 23:44 |
| vilobhmm1 | oh okay | 23:45 |

| melwitt | vilobhmm1: at a glance, it looks like nothing is done to sync it. if true, I think that driver needs some work on it to behave like the others, pull services from the db and query zk for the up/down status | 23:47 |
| vilobhmm1 | melwitt: True…I agree …may be https://review.openstack.org/#/c/138607 should help lets see | 23:51 |
