I hope not. 15:14:38 yes, i believe so 15:14:42 3k-5k per core 15:15:00 yes, per core 15:15:08 i keep fat fingering that 15:15:20 witek: we are looking at performance of python 15:15:31 if it looks good, then we will stick with python 15:15:43 because we LOVE python 15:15:43 if not, then we'll look at the options 15:15:49 :) 15:15:52 thanks 15:16:00 ;-) 15:16:08 i was thinking scala would be our first choice 15:16:18 we really do love scala 15:16:29 golang would be second 15:16:30 seriously 15:16:37 not so much love there 15:16:59 no, i wasn't being serious 15:17:09 we aren't looking at scala or golang 15:17:20 yet 15:17:21 let's see how the python performance looks 15:18:04 i need a sarcasm emoii in irc 15:18:08 do they have one of those? 15:18:21 for those interested in lucene/cassandra https://github.com/Stratio/cassandra-lucene-index/blob/branch-3.0.8/doc/documentation.rst 15:19:14 just so folks understand, lucene gets added as a plugin to cassandra, and then can be used to build secondary indexes and searched 15:19:21 do you want to compare it with the results without lucene? 15:19:57 we have difficulty modelling our functionality with just cassandra alone 15:20:21 so, we need lucene to maintain the API as it is 15:21:01 if someone can come up with a cassandra only implementation that efficiently does what the monasca api needs to do, please share it with us 15:21:38 Here is the etherpad which has all the links to the proposed schemas so far 15:21:39 https://etherpad.openstack.org/p/monasca_cassandra 15:22:14 ddieterly: is the one we are looking at right now listed? 15:22:18 we should have a contest to see if someone can do it 15:22:35 someone can do it for sure 15:22:38 rhochmuth not yet, i'm getting the lucene indexes in place first 15:22:46 the issue is performanace 15:23:54 the price will be a trip to colorado and dinner with rhochmuth 15:24:07 s/price/prize 15:24:16 or maybe it is a price 15:24:20 lol 15:24:22 not much of an incentive 15:24:22 ha, ha 15:24:48 pri?e 15:24:59 so, are there any other topics to discuss 15:25:04 release plans update 15:25:07 ? 15:25:19 that caused me a bit of pain last week 15:25:49 I've seen your discussion with Doug Hellmann 15:25:58 thanks for clarifying this 15:26:23 well, i hope in the ocata release i can get everything done better 15:26:29 more timely 15:26:44 i think evewrything would have been super easy if i had updated tags 15:27:02 prior to when python-monascaclient and monasca-statsd were branched 15:27:14 unfortunately, i missed the train on that 15:27:28 it looks like we are in good shaped with all the other repos 15:27:53 and we can try and merge master to newton after oct 6th 15:28:16 although, theere might be some push-back on some of the commits 15:28:20 i guess we'll see 15:28:35 witek: so are you ok with everthing so far 15:28:48 yes 15:28:52 it isn't ideal, but i don't think i can do better 15:29:00 other than tag on-time next time around 15:29:06 witek: thx 15:29:50 are there any other topics then? 15:30:11 could you share the schedule for design summit sessions, please? 15:30:23 i don't have it, but i should 15:30:30 i'll have to track that down 15:30:34 i'll send email 15:30:39 thanks 15:30:50 who will be at the summit? 15:30:54 we also need to be preparing for the sessions 15:31:05 yes 15:31:44 Kamil, Tomasz and me from Fujitsu EST and Poland 15:31:55 rhochmuth and ddieterly will be thee 15:31:59 shinya will be there 15:32:10 Kouji? 15:32:20 also hopefully a couple of folks form hpe bristol for monasca-analytics 15:32:51 hisashi and daisuke 15:33:09 probably i'll be 15:33:11 rhochmuth: we will be there. 15:33:30 hosanai: thx 15:33:54 i still don't have a definitive statement from luis and the team in bristol 15:34:03 hopefully tomorrow i'll know more 15:34:22 rhochmuth: i think so too :-) 15:35:11 anymore topics for today then? 15:35:40 none from me 15:36:27 ok, then i'l going to end the meeting 15:36:35 ciao! ciao! 15:36:39 bye everyone 15:36:42 bye 15:36:44 thanks, bye 15:36:49 thanks 15:36:49 #endmeeting
