02:03:56 <wanghao> hi guys
02:03:59 <gecong_> hi
02:04:02 <gengchc2_> hi
02:04:06 <wanghao> haha
02:04:15 <wanghao> seems wxy not here
02:04:27 <wxy> o/
02:04:34 <wxy> ;)
02:04:40 <wanghao> OK
02:05:03 <wanghao> today we will focous the Rocky plan
02:05:11 <wanghao> so let's jump into it
02:05:18 <wanghao> #topic Rocky plan
02:05:32 <wanghao> https://etherpad.openstack.org/p/zaqar-rocky-plan
02:05:56 <wanghao> here is list of rocky plan,  is there anything else missing?
02:07:36 <wanghao> Now we have nine items here,  and some have good begin
02:08:18 <gengchc2_> I want to add to the function[Remove pool group totally in Rocky]!
02:08:38 <wanghao> sure
02:09:25 <wanghao> plz feel free to add yourself to item which you want to join
02:10:00 <gengchc2_> Gecong and I add to the function[Introduce topic resource for notification]!
02:11:32 <wanghao> From my side, I think the quota, topic resource, remove pool group have higher priority level
02:11:37 <wanghao> gengchc2_: sure
02:11:51 <wxy> I leave some comment for quota.
02:11:55 <wanghao> we can work together for coding this
02:12:08 <wxy> It's not ready in Keystone.
02:12:18 <wanghao> wxy: yes, that I want to ask next
02:12:31 <wanghao> wxy: do you think is there anything we can do in Rocky?
02:12:52 <wanghao> wxy: or we just wait the Keystone in S
02:13:05 <wxy> quota contains two parts: limit and usage
02:13:17 <wxy> limit will be handled by Keystone.
02:13:42 <wxy> What Zaqar should do is to query limit from keystone can enforce the usage
02:13:58 <wanghao> so we can prepare the usage in Rocky first?
02:14:27 <wxy> But it's not easy to just adopt usage without limit.
02:14:46 <wxy> I suggest we should wait for keystone.
02:14:58 <wxy> there will be a new oslo lib comming soon.
02:15:45 <wanghao> there is two ways that we can think about, 1 we implement the limit and usage in Rocky by ourselves, and then switch to keystone when it is ready
02:16:00 <wanghao> second way is we will wait for keystone in S
02:16:35 <gengchc2_> I suggest we wait keystone in s.
02:17:39 <wxy> I prefer the second way. Quota system is not a easy feature. We should not waste our energy for something which would be deprecated in the future.
02:17:58 <wanghao> okay , no hurry to introduce the quota since we lost it for a long time.
02:19:22 <wanghao> another work is the performance improvement.
02:20:20 <wanghao> gengchc2_: gecong_: I remember you have tested the preformance under keystone cache.
02:20:34 <gengchc2_> yes
02:20:48 <wanghao> seems still have some issue that impact the performance
02:21:23 <wanghao> so I still hope we can have a deep look in it. wdyt
02:21:34 <wxy> gengchc2_: could you say more here? I'm sorry that I forget the detail.
02:22:54 <gengchc2_> There are some issue under the keystone cache:When multiple clients  are tested, token will be applied, resulting in a significant decline in performance
02:25:03 <wxy> Is it the issue for Keystone?
02:25:18 <wanghao> wxy: seems not
02:25:38 <wanghao> we use the keystone cache, it works fine
02:25:44 <gengchc2_> If we don't use Keystone， and use redis as management and redis as message store, 3200messges --3500messages persecond in 32 core.
02:27:25 <wanghao> but I still didn't get why the performance decline so much when using the keystone cache.
02:27:42 <wanghao> we need time to look into it I think.
02:28:15 <wanghao> we can discuss this more after the meeting.
02:28:24 <gengchc2_> Multiple clients sometimes apply for token, performance  degradate，even if we have  applied for a good token in advance.
02:28:44 <gengchc2_> ok
02:28:55 <wxy> sure. Maybe we sill need to support long connection for wsgi.
02:30:05 <wanghao> emm, it's maybe a good way.
02:30:50 <wanghao> okay, this performance issue will be the tenth item in this list.
02:31:17 <wanghao> so, if no more plan we want to add, we will jump to next topic.
02:31:41 <gengchc2_> Can the websocket in zaqar replace the long connection for wsgi?
02:33:14 <wanghao> you mean we suggest to user to use websocket if they want the high performance?
02:33:25 <gengchc2_> yes
02:33:25 <wxy> gengchc2_: it could. But websocket in Zaqar is not strong enough and well tested.
02:33:38 <gengchc2_> ok
02:34:22 <wanghao> wsgi seems to be used more widely.
02:34:49 <wanghao> as a cloud service
02:35:47 <wanghao> okay next topic: meeting time
02:35:55 <wanghao> #topic meeting time
02:36:31 <wanghao> last week, feilong and I discuss the meeting time a little.
02:37:34 <wanghao> do you think it's better to change our meeting time to biweekly?
02:37:37 <gecong_> then , what time do you prefer
02:38:20 <gecong_> I agree
02:38:29 <gengchc2_> I agree too.
02:38:39 <wanghao> we still hold the meeting at 10:00 UTC+8 in Tuesday
02:38:57 <gecong_> ok
02:39:24 <wanghao> ok
02:39:28 <gengchc2_> ok
02:39:29 <wxy> both are OK for me.
02:39:34 <wanghao> sure haha
02:40:20 <wanghao> so, next topic
02:40:30 <wanghao> topic: code review
02:41:10 <wanghao> hope everyone to have more and good reviews in Rocky too.
02:41:19 <gecong_> ok
02:41:23 <gengchc2_> ok
