| bknudson | zzzeek: do you know why oslo.cache would have a PooledMemcachedBackend ? | 20:10 |
| bknudson | dogpile has a ClientPool class, but maybe it only has a single client? https://github.com/dprince/dogpile.cache/blame/master/dogpile/cache/backends/memcached.py#L121 | 20:11 |
| bknudson | or, looks like you'd get 1 per thread. | 20:11 |
| zzzeek | bknudson: um....the memcached client should be using some kind of thread local thing, it depends on the memcached api | 20:12 |
| zzzeek | bknudson: yah i dont think you need any pooling on top of that. havent looked ina long time tho | 20:13 |
| bknudson | not sure what the point of a 10-client pool would be... maybe if you had lots of threads. But python couldn't use all those threads anyways. | 20:14 |
| bknudson | also, might be better to have a few extra connections around in case 1 fails. | 20:14 |
| bknudson | but that would require 10 connections to be in use at once to fill it up, which would never happen. | 20:16 |

| bknudson | zzzeek: what do you think about moving oslo.cache's PooledMemcachedBackend to dogpile.cache? Shouldn't be anything openstack-specific. | 20:26 |
| zzzeek | bknudson: what does it do that the current one doesnt? | 20:27 |
| *** kgiusti has left #openstack-oslo | 20:27 | |
| bknudson | zzzeek: good question. I'm going to try it to see what the diff in behavior is. | 20:27 |
| zzzeek | bknudson: that is, im not sure why we need a pool. | 20:27 |
| bknudson | here's the commit message: https://github.com/openstack/oslo.cache/commit/fbbfbff36a54525b36b552bfe04ada637ecd297e | 20:27 |

| zzzeek | bknudson: we're alraedy doing a connection-per-thread in dogpile. now, perhaps this doesn't work very well if you have 1000 greenlets | 20:31 |
| bknudson | zzzeek: I'm wondering - the the dogpile impl close/re-open the connection every time? | 20:31 |
| zzzeek | bknudson: id need to see the problem that was observed which led to adding this backend | 20:31 |
| zzzeek | bknudson: i dont think so. | 20:32 |
| bknudson | keystone doesn't even support eventlet anymore. | 20:32 |
| zzzeek | right but this is oslo.cache | 20:32 |
| dstanek | bknudson: i think that silly backend may have originated in keystone code | 20:34 |
| bknudson | dstanek: the help text for the backend config option makes it sound pretty awesome. | 20:35 |
| dstanek | bknudson: on another caching note...i think i got the region invalidation problem figured out | 20:36 |
| dstanek | i may need to push another patch update though | 20:36 |
| bknudson | dstanek: what's the problem with region invalidation? | 20:41 |
| dstanek | bknudson: it doesn't work across processes | 20:41 |
| bknudson | dstanek: why didn't it work? | 20:42 |
| dstanek | bknudson: dogpile.cache doesn't use regions how we thought it did. wasn't designed that way from what i can tell | 20:43 |
| stevemar | bknudson: it never worked across processes | 20:43 |
| bknudson | A succinct API which encourages up-front configuration of pre-defined “regions”, each one defining a set of caching characteristics including storage backend, configuration options, and default expiration time. | 20:44 |
| bknudson | https://pypi.python.org/pypi/dogpile.cache ^ | 20:44 |
| bknudson | dstanek: "regions" in quotes. | 20:44 |
| dstanek | https://review.openstack.org/#/c/349704/ | 20:44 |
| patchbot | dstanek: patch 349704 - keystone - WIP: region namespace POC for cache invalidation | 20:44 |
| dstanek | gotta fixup and push my latest for that | 20:44 |
| bknudson | dstanek: looks like it needs some work. | 20:44 |
| *** tonytan4ever has joined #openstack-oslo | 20:45 | |
| bknudson | uses tabs instead of spaces! | 20:45 |
| bknudson | rookie mistake. | 20:45 |
| dstanek | lol | 20:45 |
| bknudson | dstanek: how do all the processes get the same key? | 20:47 |
| dstanek | bknudson: extra memcached hit in my scheme | 20:47 |
| bknudson | it looks like the processes don't share a cache at all. | 20:47 |

| dstanek | bknudson: so basically there is a key 'func:args:...:region_id' that holds a uuid. that uuid is then used in 'func:args:...:uuid' to hold the real value this is being stored | 20:50 |
| dstanek | this is a scheme i've used a lot in the past | 20:51 |
| dstanek | for example, consider a store that shows products in multiple ways or have cached data for different project views (in a catalog, pricing page, etc). we would use the product_id key to lookup a uuid that would then be used by all those other cache keys | 20:52 |
| dstanek | so when a product was updated in our CMS only the product_id key was updated and my the magic of memcached the other keys no longer pointed to values | 20:52 |
| bknudson | dstanek: I hope you got paid a lot for your past work because it sounds super boring. | 20:54 |
| dstanek | bknudson: lol, that's why i'm not there anymore | 20:54 |
| bknudson | dstanek: just wondering since I have no idea how this works -- is there a persistent dogpile backend where this wouldn't work? | 20:56 |
| bknudson | as in, it would leave a large amount of orphaned data | 20:56 |
| dstanek | bknudson: you mean if the backend doesn't support expiring its data? | 20:57 |
| bknudson | dstanek: I thought there was a bug where we weren't setting the expiration. | 20:58 |
| dstanek | bknudson: yep, working on a patch for that in my patchset. memcache would reclaim the orphaned space even without an expiration | 20:59 |
| bknudson | dstanek: y, I'm not worried about memcached | 20:59 |
| dstanek | bknudson: i've been spending way too much time in our caching code | 20:59 |
| bknudson | rip it out and start over. | 21:00 |
| dstanek | well, as far as keystone is concerned we'll be fine because we will be setting expiration | 21:00 |

| cfriesen | question about oslo.versionedobjects. Suppose I have a remotable object function that modifies a field, then we call obj_make_compatible() to downgrade the version, and that removes the field I modified. | 21:51 |
| cfriesen | should the core osloversionedobjects code remove the field from the list of changed fields? | 21:52 |
