flaper87ekarlso: redis06:35
ekarlsoflaper87: any clue on why cassandra isn't used yet ?06:35
flaper87ekarlso: no one has written one :D06:36

flaper87ekarlso: Someone came to us proposing it not long ago06:36
flaper87ekarlso: I don't recall who that person is but it'd be interesting06:36

ekarlsowhy ES ?06:37
*** saera has quit IRC06:39
*** saera has joined #openstack-zaqar06:41
flaper87ekarlso: because it's fast enough and has a great, buil-in, replication system.06:42
flaper87Also, playing with indexes will give us different performance results06:42
flaper87I'm not a cassandra expert but I did read somewhere that it's not good for "queueing systems"06:42
flaper87ekarlso: have you heard anything about that?06:43
ekarlsoflaper87: nope :P06:43
flaper87ekarlso: http://www.datastax.com/dev/blog/cassandra-anti-patterns-queues-and-queue-like-datasets06:43
flaper87ekarlso: not sure how updated that blog post is, though.06:45
flaper87it's probab;y old and obsolete06:45
ekarlsoPRIL 26, 2013  ;P06:45
flaper87ekarlso: haha, yeah. I mean, unless Cassandra changed the way it stores things, I think the post is still valid. But again, I don't know much about cassandra06:47

earnThisHi all, anyone know of anymore low hanging fruit style bugs that are unreported I might be able to take a crack at. you guys seem busy lately14:07
kgriffsflaper87: o/14:11
kgriffshow are you?14:11
* kgriffs is on a shuttle bus between Rackspace offices14:12
kgriffsmalini: do you know what the oldest version of RHEL/CentOS we need to support for Zaqar?14:19
malinikgriffs: no14:19
kgriffsI'm trying to figure out whether we can depend on redis 2.614:20
kgriffsmalini: what was it they ran in the gate?14:20
kgriffs(what version of centos)14:20
maliniwas checking that :)14:20
kgriffskk, thanks!14:20
malinithey have centos614:21
maliniwonder if openstack has supported OS list somewhere..I cudnt find anything with a quick search14:22
maliniwell..they dont need tht - rt?14:22
malini:D14:22
kgriffsin my control panel for RAX I can spin up 5.10 and 6x14:22
kgriffsso, I guess our baseline is 6 since that is what's in the gate?14:22
kgriffsmeaning, if we want to gate on Redis, we will be limited to whatever 6x does? Trusty has redis 2.8 btw14:23
maliniwhich other projects have redis?14:26
maliniI think we shud be ok14:26
malinisince we will use redis for tempest tests & they are already on trusty14:26
malinido we need redis for unit tests?14:27
kgriffsperhaps. If we remove the data plane driver for sqla then we will need something14:30
kgriffs#info centos6 installs 2.4 from epel14:31

flaper87Planning to send something along those lines before the EOD16:56
flaper87kgriffs|afk: can I mark teh redis bp as implemented?17:01
flaper87is there any essential patch missing?17:01
notmynameflaper87: seems reasonable17:02
flaper87notmyname: awesome, thanks :)17:02
notmynameflaper87: you may want to mention technical reasons you have chosen some nosql storage instead of using database foo (or abstraction bar)17:03
flaper87notmyname: +1 I'll add that17:03
flaper87malini: hey hey! You've been away lately! Glad to see you around!17:04

kgriffsearnThis: I can help in a few minutes once I finish this redis patch.18:09
earnThiskgriffs: appreciate it, take your time though18:10
kgriffsearnThis: hmm, looks like for some reason oslo.utils was not installed by tox correctly18:31
kgriffsthat can happen sometimes if there is a conflict between pip install with and without symlinks (the -e option)18:32
kgriffsalso, it can happen if a dependency changed in the latest code - tox isn't great at knowing it needs to recreate an env18:32
kgriffsearnThis: have you tried recreating??18:32
kgriffstox -re py2718:32
earnThiskgriffs, i have not, will do no18:33
earnThisnow*18:33
kgriffskk, let me know how it goes18:34
earnThiskgriffs: well right off the bat its taking longer than the run when i got the error so that's promising, will keep you posted18:36
*** sgotliv has quit IRC18:38
earnThiskgriffs: no luck  http://paste.openstack.org/show/105355/18:42
kgriffsoh, well that's a different error18:42
kgriffsso you an remove the 'r' flag now that you are past the oslo.utils thing18:43
earnThisrunning now18:45
kgriffsAttributeError: 'Resource' object has no attribute 'driver'18:45
kgriffsthat is really strange18:45
kgriffsbecause in the __init__ for that class, it assigns to self.driver18:45
kgriffsflwang or alcabrera: this could use approval - https://review.openstack.org/#/c/118468/18:48
earnThiskgriffs: in the patch i am testing the attribute should be '_driver'18:49
kgriffsoic18:49
* alcabrera clicks18:49
alcabrerakgriffs: it is done - manual GC is approved. :)18:52

kgriffsthanks!19:01
kgriffs(note the comments in the previous patchset)19:01
kgriffsearnThis: hmm, looks like that on_get is blowing up still. you may need to use pdb per the instructions toward the bottom of this wiki page:19:04

* flaper87 back19:38
flaper87kgriffs: I think we can close the redis bp even without that patch. Not saying we shouldn't review it but in terms of features it is complete19:38
flaper87am I wrong?19:38
kgriffswithout this patch, stats are incorrect after a GC iirc19:39
kgriffsyou can consider it a bug if you like19:39
