DinaBelovaokay, so let's get started :)15:32
DinaBelova#topic Action Items15:32
DinaBelovalast time we had two action items15:32
DinaBelovaone was regarding making osprofiler review queue a bit less :) thanks to Vipin and Boris it actually happened15:32
*** chyka has joined #openstack-performance15:33
DinaBelovatovin07 two more patches from you are almost ready to be merged, may you please fix them?15:33
DinaBelovaso we can actually do it15:33
tovin07yes15:33
tovin07:D15:33
DinaBelovathe second action item was about adding details to the https://etherpad.openstack.org/p/performance-team-q-release-ideas but frankly speaking it is a failure :) none has aded anything :D so it looks like we need to duplicate this action item again :)15:34
msimoninoups15:34
DinaBelova#action ilyashakhat msimonin rcherrueau tovin07 rajulk DinaBelova add ideas to https://etherpad.openstack.org/p/performance-team-q-release-ideas15:34
msimonintotally forgot about this15:35
DinaBelovait looks like all we did :D15:35
ilyashakhatstill have it on todo list15:35
msimoninactually there is one idea : tovin07 :)15:35
tovin07:))15:35
DinaBelovalet's try to be more productive next week :D15:35
DinaBelovaso let's go further15:36
DinaBelova#topic Current status15:36
DinaBelovatovin07 please go ahead15:36
tovin07I has nothing for last week. It was my national holiday :D15:36
DinaBelovatovin07 okay :) it's a good thing anyway :)15:37
DinaBelovamsimonin rcherrueau any news on the current testing / cockroachdb work?15:37
msimoninis rcherrueau here ?15:38
DinaBelovahe was :D15:38
rcherrueauyep15:38
rcherrueauI pushed an email last week15:39
rcherrueau#link http://lists.openstack.org/pipermail/openstack-dev/2017-September/121779.html15:39
rcherrueauthat explains the status of the POC we made15:40
rcherrueauI also wanna write a test plan for cockroachdb, so I asked some help to CockroachDB guys.15:41
rcherrueauthat's all on my side15:41
DinaBelovathanks rcherrueau15:42
DinaBelovamsimonin ? :)15:42
msimoninFirst One thing regarding what rcherrueau said15:42
msimoninthere was a feedback about how the migrations were made in Keystone15:43
msimoninit seems that Keystone is using an old(deprecated) project to handle the database migrations15:43
msimoninthis breaks hardly with cockroach15:43
msimoninthe suggestion was to move to alembic to manage the migrations15:43
msimoninany idea on the effort it requires to move to alembic ?15:44
msimoninit seems some other projects did it15:44
DinaBelovamsimonin well, it's major change in fact. And this requires separate development effort to get it done15:44
msimoninThis is what I thought :)15:45
DinaBelovaso I'd say this is about a 1-2 weeks or so to get it POC-level working , and then nobody-knows-how-much time to get it approved to the keystone itself :)15:45
msimoninI see15:46
msimoninSo from the performance point of view there will be an evaluation on using cockroach15:46
DinaBelovabut frankly speaking I'm surprised :) I did not take a look on keystone for a while, but 2 years ago they were planning to migrate to alembic eventually15:46
msimoninyes they eventually do15:47
msimonin:)15:47
DinaBelovait looks like this "eventually" never came to reality15:47
DinaBelova:D15:47
DinaBelovaokay, msimonin, this was "first one thing" :) and the second one?15:48
msimoninWe are still preparing the amqp1.0 evaluation15:49
msimoninNo significant progress (some more tooling as usual)15:50
msimoninThat's all :)15:50
DinaBelovathank you for the update :)15:50
DinaBelovailyashakhat anything from your side to share?15:51
ilyashakhatno - I dedicated some time to os-faults, and that's all I did for community this week15:51
DinaBelovailyashakhat thank you sir, good to know :)15:52
DinaBelovaokay, it looks like we're really quick today :)15:52
DinaBelovalet's jump to the open discussions15:52
DinaBelova#topic Open Discussion15:52
DinaBelovamsimonin rcherrueau tovin07 ilyashakhat - anything to raise on the discussion?15:53
rcherrueauMaybe one request regarding osprofiler15:53
ilyashakhattovin07, do you have any specific plans for completing opentracing initiative?15:53
tovin07this time, I have got travel support from OpenStack Foundation15:53
tovin07ilyashakhat: yes15:53
rcherrueauThere are two kind of messages: rpc and notify. I think that osprofiler traces both as rpc ones.15:55
tovin07will anyone attend Sydney Summit this Nov?15:55
DinaBelovatovin07 any ideas when opentracing will be completed? :) as for the Sydney summit - it's not yet clear for me :(15:55
tovin07rcherrueau: rpc and notify?15:55
rcherrueauyes, oslo.messaging.rpc and oslo.messaging.notify15:56
tovin07DinaBelova: hope it will be finished in this Q-cycle15:57
tovin07rcherrueau: can you give me a link for that?15:57
rcherrueauand inside rpc there are two kinds of call: call and cast15:57
DinaBelovatovin07 ack15:57
rcherrueautovin07: https://docs.openstack.org/oslo.messaging/latest/reference/index.html15:59
tovin07rcherrueau: hmm, okay, let make this as an action item for me :D15:59
rcherrueauI am particularly interested by making the difference between rpc.call and rpc.cast16:00
DinaBelovarcherrueau I believe you're right. We do not have this separation from the osprofiler standpoint. But in reality we do not trace notify, am I right? Notify i using by openstack services that would like to notify something else about whatever. But if we're tracing the api call to openstack project, we're using call to call remotely other service?16:00
DinaBelovaso notify is out of tracing here, as it's not related (please correct me if I'm wrong) to the OpenStack api tracing16:00
rcherrueauDinaBelova: I don't take a look for a while. I guess you're right.16:01
DinaBelovaas for the diff between call/cast - it makes sense to set up this differentiation I belive16:01
rcherrueauThanks, diff between call/cast will be really helpful16:02
DinaBelovatovin07 rcherrueau so it looks like it makes sense to take a look on how to separate cast/call in oprofiler16:02
DinaBelovayeah16:02
tovin07yep16:02
DinaBelovatovin07 shoul I create an action item?16:02
tovin07yes16:02
*** markvoelker_ has joined #openstack-performance16:02
DinaBelova#action tovin07 identify how to separate call/cast rpc calls within osprofiler tracing16:03
DinaBelovamsimonin rcherrueau ilyashakhat tovin07 anything else?16:03
tovin07nope16:03
rcherrueaunope16:03
