aostapenkoWe have no action items from previous meeting and no special status in agenda. So I propose to walk through statuses14:15
aostapenkodukhlov, what about your patch https://review.openstack.org/15251314:15
aostapenkoMoving to cassandra 2.1.214:16
dukhlovhm, I faced with some strange behavior14:17
aostapenko#topic Moving to cassandra 2.1.214:18
dukhlovIt works fine, but our tests on gate work very slow and even don't meet job timeout sometimes14:18
dukhlovI'm troubleshooting this problem14:18
dukhlovwhat I know now...14:18
dukhlovproblem is only with test_list_tables14:19
dukhlovthere we create a few table (5)14:19
dukhlovand then when test is over we cleanup those tables14:20
dukhlovmagnetodb processes this request , set status to DELETEING and create job for async task manager14:21
dukhlovthen I see in logs that this job is processed and DELETE FROM table_info WHERE tenant=<tenant> AND name=<table_name> executed14:22
aostapenkolist_tables has its own cleanup mechanism. I will try to assist you with this investigation14:24
dukhlovbut our tests in this time are executing describe table to get information that table is deleted and somehow after job execution it keep receive that table is DELETING for 2 minute14:24
dukhlovand then somehow table is gone at least14:24
dukhlovwhy we have such delay for 2 minute - I still can not understand and continue investigation14:25
aostapenkoIt's our default delay for deleting table in tempest14:26
dukhlovaostapenko: I saw it14:26
dukhlovbut in case of timeout it should raise exception14:26
aostapenkoAre you sure that table is gone? Not DELETE_FAILED state14:27
dukhlovI am sure14:27
dukhlovAt least I think so14:27
aostapenkoOk. Lets continue an investigation14:27
aostapenko#action dukhlov aostapenko Investigate problem with tempest tests in https://review.openstack.org/15251314:29
aostapenkoAnything else, dukhlov?14:29
dukhlovnot today14:30
aostapenkoLets move on. miqui, what are you working on?14:31
miquinothing specific atm, more focused on learning some cassandra basics14:32
miquiand getting my dev env to work14:32
aostapenkomiqui: thank you for your patches on table creation validation14:33
aostapenkoI'm still working on refactoring and extending healthcheck request14:35
aostapenkooh, excuse me. That are not your patches. Thanks to vivekd :)14:36
miqui..no worries...14:36
*** charlesw has joined #magnetodb14:37
aostapenkoDoes anybody has to say something?14:37
aostapenkooh, hi, charlesw14:37
charleswHi guys14:38
aostapenkocharlesw: Could you share a status of your notification system refactoring?14:38
charleswYes14:38
aostapenkoplease14:39
charleswIt's close to done. Going thru the notification refactoring comments from Dima. had some offline discussion.14:39
charleswWill send out an updated patch.14:40
aostapenkocharlesw: anything else you are working on?14:40
charleswFor now, we will use existing celiomenter doc for evnets. But we will need to update the ceilometer doc.14:41
charleswAnyone knows the process?14:41
charleswI have an internal project to integrate metrics into a portal.14:41
charleswI will need to convert health_check API results into metrics to be sent to StatsD14:42
charleswWas thinking about a daemon process to call health_check peridically14:42
aostapenkocharlesw: now we have a problem with integration with ceilometer. We need to transfer to not durable queues. I will send a patch soon14:42
charleswSo the community work I have in mind next is to create such daemon to call health_check/monitoring API to periodically convert API call results to metrics14:44
aostapenko#action aostapenko Make a patch to make magnetodb to use nondurable queues14:45
charleswIf it's ok, I will create a blueprint14:45
*** nunosantos has joined #magnetodb14:46
aostapenko#action charlesw Create a blueprint on periodically convert healthcheck API call results to metrics14:46
aostapenkoHi nunosantos14:47
aostapenkodukhlov, do you have any thoughts about that?14:47
*** Cl has joined #magnetodb14:47
aostapenkocharlesw, waiting for bp14:48
dukhlovI think we go in the same direction with openstak14:48
aostapenkoagree14:49
charleswdukhlov, could you be more specific?14:49
dukhlovit looks like oslo.messaging does not support different configuration for different topics14:49
dukhlovso we can only make all topics durable or make all topics not durable14:50
dukhlovNot it should be openstack wide option for avoid conpatibility problems14:50
dukhlovso all topics should be durable or not durable14:51
miquiquestion, but diff openstack projects that config rabbit in diff ways?14:51
dukhlovin devstack topics are not durable14:51
miquior they seem to agree on what type of queues to use (i.e. durable vs not)14:51
charleswShould we go to oslo messaging instead asking for support to configuring durability for different q14:52
dukhlovmiqui, yes different project have diff configuration14:52
aostapenkomiqui ceilometer notification agent forces us to use its own configuration for notification queue14:52
miquik, thanks...14:53
dukhlovbut different projects usually use the same topic14:53
miquiah k..14:53
dukhlovfor communication14:53
miquiso then all of this depends on how ceilometer configs its queue regardless of oslo no?14:54
miquiceilometer has a msg topo that all have to abide by right?14:54
*** keith_newstadt has quit IRC14:54
aostapenkoceilometer creates exchanges for all other services. And for its redeclaration config (e.g. durability) should be the same14:56
dukhlovmmm, I'm not fully agreed with your terms, but yes14:56
miquik..14:56
aostapenkoDoes anybody have to add something?14:57
aostapenkoOk. lets move to open discussion14:58
aostapenko#topic Open Discussion14:58
miquiam fine thanks....14:59
aostapenkowe are out of time. Does anybody have something to share or any questions?15:00
charleswsomehow I received a cancellation request of this meeting15:01
charleswjust want to make sure the meeting is still good going forward15:01
aostapenkocharlesw, thank you. I'll figure this out15:02
aostapenkoSo lets finish. Thank you, guys15:04
