I hope not. 15:14:38 <ddieterly> yes, i believe so 15:14:42 <rhochmuth> 3k-5k per core 15:15:00 <ddieterly> yes, per core 15:15:08 <ddieterly> i keep fat fingering that 15:15:20 <rhochmuth> witek: we are looking at performance of python 15:15:31 <rhochmuth> if it looks good, then we will stick with python 15:15:43 <ddieterly> because we LOVE python 15:15:43 <rhochmuth> if not, then we'll look at the options 15:15:49 <witek> :) 15:15:52 <witek> thanks 15:16:00 <ddieterly> ;-) 15:16:08 <rhochmuth> i was thinking scala would be our first choice 15:16:18 <ddieterly> we really do love scala 15:16:29 <rhochmuth> golang would be second 15:16:30 <ddieterly> seriously 15:16:37 <ddieterly> not so much love there 15:16:59 <rhochmuth> no, i wasn't being serious 15:17:09 <rhochmuth> we aren't looking at scala or golang 15:17:20 <ddieterly> yet 15:17:21 <rhochmuth> let's see how the python performance looks 15:18:04 <rhochmuth> i need a sarcasm emoii in irc 15:18:08 <rhochmuth> do they have one of those? 15:18:21 <ddieterly> for those interested in lucene/cassandra https://github.com/Stratio/cassandra-lucene-index/blob/branch-3.0.8/doc/documentation.rst 15:19:14 <rhochmuth> 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 <witek> do you want to compare it with the results without lucene? 15:19:57 <ddieterly> we have difficulty modelling our functionality with just cassandra alone 15:20:21 <ddieterly> so, we need lucene to maintain the API as it is 15:21:01 <ddieterly> 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 <rhochmuth> Here is the etherpad which has all the links to the proposed schemas so far 15:21:39 <rhochmuth> https://etherpad.openstack.org/p/monasca_cassandra 15:22:14 <rhochmuth> ddieterly: is the one we are looking at right now listed? 15:22:18 <ddieterly> we should have a contest to see if someone can do it 15:22:35 <rhochmuth> someone can do it for sure 15:22:38 <ddieterly> rhochmuth not yet, i'm getting the lucene indexes in place first 15:22:46 <rhochmuth> the issue is performanace 15:23:54 <ddieterly> the price will be a trip to colorado and dinner with rhochmuth 15:24:07 <ddieterly> s/price/prize 15:24:16 <ddieterly> or maybe it is a price 15:24:20 <ddieterly> lol 15:24:22 <rhochmuth> not much of an incentive 15:24:22 <pratid> ha, ha 15:24:48 <pratid> pri?e 15:24:59 <rhochmuth> so, are there any other topics to discuss 15:25:04 <rhochmuth> release plans update 15:25:07 <rhochmuth> ? 15:25:19 <rhochmuth> that caused me a bit of pain last week 15:25:49 <witek> I've seen your discussion with Doug Hellmann 15:25:58 <witek> thanks for clarifying this 15:26:23 <rhochmuth> well, i hope in the ocata release i can get everything done better 15:26:29 <rhochmuth> more timely 15:26:44 <rhochmuth> i think evewrything would have been super easy if i had updated tags 15:27:02 <rhochmuth> prior to when python-monascaclient and monasca-statsd were branched 15:27:14 <rhochmuth> unfortunately, i missed the train on that 15:27:28 <rhochmuth> it looks like we are in good shaped with all the other repos 15:27:53 <rhochmuth> and we can try and merge master to newton after oct 6th 15:28:16 <rhochmuth> although, theere might be some push-back on some of the commits 15:28:20 <rhochmuth> i guess we'll see 15:28:35 <rhochmuth> witek: so are you ok with everthing so far 15:28:48 <witek> yes 15:28:52 <rhochmuth> it isn't ideal, but i don't think i can do better 15:29:00 <rhochmuth> other than tag on-time next time around 15:29:06 <rhochmuth> witek: thx 15:29:50 <rhochmuth> are there any other topics then? 15:30:11 <witek> could you share the schedule for design summit sessions, please? 15:30:23 <rhochmuth> i don't have it, but i should 15:30:30 <rhochmuth> i'll have to track that down 15:30:34 <rhochmuth> i'll send email 15:30:39 <witek> thanks 15:30:50 <ddieterly> who will be at the summit?
