*** demorris has quit IRC16:51
SlickNikWe can definitely change the troveclient representation of the response to make it look better, if that's what you mean denis_makogon16:54
denis_makogonSlickNik, yes, as one of the possible variants16:55
*** zuqiang has joined #openstack-trove16:55
denis_makogonSlickNik, you can verify the bug by the creating the new rules and then list available groups16:56
denis_makogonbasically, the pretty table column contains N JSON's and it looks ugly16:57
SlickNikI'm on my way in to the office right now, so can't do that.16:57
SlickNikI know what you're talking about thogh.16:57

*** denis_makogon_ is now known as denis_makogon18:30
esmutehi denis_makogon18:31
denis_makogonesmute, hello again18:31
esmutethe idea is to have cross region backup support18:31
denis_makogonesmute, have you thought about backup replication use case ?18:31
esmuteso we can use a backup that was created from one region in a different region18:31
denis_makogonesmute, i get it, just digging18:31
*** SnowDust has quit IRC18:32
denis_makogonesmute, so, you think moving is the right option ?18:32
*** ViswaV has joined #openstack-trove18:33
*** SnowDust has joined #openstack-trove18:33
*** Barker has quit IRC18:33
esmuteyes.. this use case can be solve to replication... but having cross-region backup, provides a flexible way for users who would like to have a stand alone DB... and not necessary replicated from other regions18:33
esmutei think we neeed both18:33
esmute:-)18:33
denis_makogonesmute, agreed, and we need to start from the replication, i guess18:34
esmutei think they are two different features though... This one is about reusing backups from different region.18:35
denis_makogonesmute, because user will expect that his backup is accessable from any endpoint and region18:35
denis_makogonesmute, what you think about co-operation ?18:35
esmutei think that will depend on how you setup your trove control plane.18:36
denis_makogonof course, it's always depends on the deployment18:36
esmutewhat do you mean about co-operation?18:37
denis_makogonesmute, i mean, we, you and me, can track down this beast =)18:37
denis_makogonesmute, cover both cases, moving and repliation through regions18:37
*** Barker has joined #openstack-trove18:37
denis_makogonwhat would you say ?18:38
esmutehehe i would... but i believe replication is being worked on by the tesora folks :)18:38
denis_makogonesmute, backup replication18:39
denis_makogonesmute, not the mysql replication =)18:39
denis_makogonesmute, we're talking about backup availability through the multiple regions18:40
esmutesure.. why not. what do you have in mind?18:40
denis_makogonfirst i think we need to talk to Swift guys18:40
denis_makogonand find out what they can offer to us18:40
esmutei was thinking about something simple for now... being able to copy backups cross-region.... so that the restore will work as how it is now18:41
denis_makogonwould it be the moving process or the replication18:41
denis_makogonesmute, restore wouldn't be changed18:41
denis_makogonesmute, the backup base model will have some new attributes18:42
denis_makogonlike region18:42
esmutebackups uses streaming to read/write to storage. we can leverage that for cross-region copy18:42
esmutedenis_makogon: correct... restore would be unchanged18:42
*** Barker has quit IRC18:42
esmutei was thinking that the backup model will be also unchanged.18:43
*** yogesh_ has joined #openstack-trove18:43
denis_makogonesmute, how do you plan to store the region where the backup exists ?18:43
esmuteall it is doing is creating a backup record and push it to storage... but instead of coming from a command that executes an instance backup, it comes from another storage18:44
esmutei was thinking that that stays untouched.18:44
esmuteit just creates a new copy in the destination region18:44
denis_makogonesmute, wait a bit, you said, "moving the backup through the regions", and now you telling "copy"18:45
esmutewe dont want to access the same backup object, because if that gets deleted by trove from the other region, it could get messy18:45
esmutesorry denis_makogon for the confusion. It is more like a copy18:46
denis_makogonesmute, copy is almost the replication =_18:46
denis_makogon=)18:46
*** Barker has joined #openstack-trove18:46
esmutewell... they wouldnt be synched though..18:47
esmuteif you deleted one, the other backup wouldnt be affected18:47
denis_makogonesmute, about messy deletion, if the backup will have some kind of the restriction field that would not allow to touch this backup, everything will be ok18:48
esmutei was thinking of something simple...18:48
denis_makogonesmute, ok =)18:48
denis_makogonesmute, file the BP and wiki page, then we'll talk again, it would be a bit easier18:49
esmutelook at the BP if you havent and do put some comments...we can have this discussion with the rest of the group18:49
esmutedenis_makogon: https://blueprints.launchpad.net/trove/+spec/cross-region-backup-migration18:49
denis_makogonesmute, what about the ML ?18:49
esmutelet see how much interaction we get through here and in the BP's comments... We can take it to the ML if it becomes controversial18:51
denis_makogonesmute, ML is generic, if we want to envolve all community in this convo18:52

denis_makogonesmute, if you going to edit wiki, you'll need to update the BP also and meeting page19:08
esmutedenis_makogon: changed it to 'Cross-region-backups'. i think it is what you suggested but shorter :-)19:09
esmutenoted. Thanks!19:09
denis_makogonesmute, i think work "availability" is required here, what would you say ?19:10
denis_makogonesmute, like "Cross-region-backup-availability:19:10
esmutedenis_makogon: haha.. ok.. ill change it19:11
denis_makogonesmute, if you leave as you say you'll need to describe what you actually mean19:11
denis_makogonesmute, as i understand, you want to have one backup populated through multiple nodes/regions19:12
denis_makogonsomething like that19:12
denis_makogonesmute, btw, you raised good topic - region19:13
denis_makogonesmute, not only Swift has regions19:13
denis_makogonesmute, since we're going replication and clustering, we need something like anti-affinity rules19:14
denis_makogonand anti-affinity rules ca describe the region-placement strategy19:15
denis_makogon*can19:15
denis_makogonSahara (ex-Savanna) has anti-affinity rules while provisioning hadoop clusters19:16
* SergeyLukjanov on demand19:16
denis_makogonand i guess, databases, same as dfs, has to be able to be deployed through multiple data centers19:17
SergeyLukjanovdenis_makogon, placement control is very important for replications, otherwise you could have replica vm on the same host19:17
SergeyLukjanovdenis_makogon, at least host control I think19:17
denis_makogonSergeyLukjanov, yes, right19:17
esmutedenis_makogon: i think scheduling/affinity discussion suits more with replication... but its a good point19:18
*** sbfox has joined #openstack-trove19:18
esmuteanyways.. my stomach is growling... be back later19:18
denis_makogonesmute, at least now we can make trove place VM at proposed region (nova and heat are able to handle this region attribute)19:19
SergeyLukjanovdenis_makogon, fyi you can ask nova to schedule vm on different host by using the "different_host" hint19:19
denis_makogonSergeyLukjanov, correct19:19

denis_makogonSergeyLukjanov, you mean "scheduler_hints" ?19:21
SergeyLukjanovdenis_makogon, yup19:21
SergeyLukjanovdenis_makogon, https://github.com/openstack/sahara/blob/master/sahara/service/direct_engine.py#L20719:22
SergeyLukjanovexample from sahara19:22
denis_makogonSergeyLukjanov, thanks19:22
denis_makogonSlickNik, what is the"aa_ids" ?19:23
SlickNikaa_ids?19:23
denis_makogonSergeyLukjanov, what is the"aa_ids" ?19:23
SlickNikoh, that was meant for SergeyLukjanov19:24
denis_makogonSlickNik, sorry, wrong nick mentioned =/19:24
SlickNiknp19:24
denis_makogonSergeyLukjanov, what is the actual meaning of the "aa_ids" ?19:24
SergeyLukjanovdenis_makogon, take a look at line #22119:24
SergeyLukjanovdenis_makogon, it's a map "node process -> instance ids"19:25
SergeyLukjanovdenis_makogon, our a-a is based on node process, like user could ask sahara to ensure a-a for all nodes with DataNode process on them19:25
SergeyLukjanovdenis_makogon, and sure user could ask for several such processes19:26
SergeyLukjanovdenis_makogon, so, we're storing all instances to the lists in map by node process as the key19:26
denis_makogonSergeyLukjanov, node process is the one of the hadoop services, right ?19:27
SergeyLukjanovdenis_makogon, each service could consist of several processes19:27
denis_makogonlike you said DataNode, etc.19:27
SergeyLukjanovdenis_makogon, for ex. HDFS is 1xNameNode + NxDataNode19:28
denis_makogonSergeyLukjanov, get it19:28
SergeyLukjanovdenis_makogon, where DataNodes are data blocks storages and so we'd like to guarantee "different-hypervisor" reliability for them19:28
denis_makogonSergeyLukjanov, i think we'll be in touch and we'll ask for the best practices of a-a19:30
denis_makogona-a implementation =)19:30
denis_makogonSergeyLukjanov, thanks for the short intro into the Sahara a-a =)19:31

achampionlooking at my logs I see it used to work Initializing extensions manager -> Loading extensions23:27
SlickNikachampion: Is it no longer doing that?23:27
achampionnow the logs read Initializing extensions manager -> Extended resource: extensions but nothing gets loaded23:27
achampionSlickNik: no it isn't :(23:28
SlickNikachampion: How did you install trove?23:29
SlickNikachampion: Can you try using a full path for the extensions instead of a relative path to see if that will work?23:29
achampiongit clone23:29
achampionpython setup.py install23:29
achampionok will do23:29
achampionSlickNik: fantastic full path worked - not sure how the relative paths have got screwed up, it used to work.23:36
