rm_workblogan: ?04:13
rm_workblogan: I have been waiting for you to get on steam04:13
rm_workyou popped on for like 2 minutes earlier and then bailed04:13
rm_worklol dougwig04:14
bloganlol04:16
bloganoh dougwig and his shenanigans04:16
bloganrm_work: yeah i popped on and saw no one so decided to do some work04:16
bloganwell trevor had just started04:16
rm_workblogan: i was online04:17
rm_workwaiting for you to be online :P04:17
rm_workblogan: you going to play any tonight?04:17
rm_workoh is tomorrow sprint planning?04:17
rm_workT_T04:17
bloganyeah let me get to a stopping point04:17
rm_workno rush04:17
blogan"borrowing" some of your TLS lifecycle details04:18
rm_workheh04:18
rm_workgo for it04:18
bloganyou know seqdiag has a loop and alt?04:18
bloganthough you dont know what condition the alt is on so its kind of useless04:18
rm_workerr04:23
rm_workthey do? I did not see that in their docs04:23
rm_workdid you find better docs? >_>04:23
rm_worki'll revise with that04:23
rm_worklack of loop was annoying04:24
rm_workblogan: ^^04:24
bloganrm_work: no i looked through the source code04:27
rm_workoh, I have been using this which is awesome: https://github.com/mhaig/vim-blockdiag-series04:27
bloganrm_work: they're experiemental04:27
rm_workmarkup for vim04:28
rm_workblogan: lol awesome, have to look through their source to see what possible syntax is <_<04:28
rm_workthat's special04:28
bloganrm_work: well i was looking for something else, but found those along the way04:28
rm_workheh04:28
rm_workcool, i'll look tomorrow04:28
blogancouldn't find a condition statement though, so still have to use the separators04:29
bloganthis amphora lifecycle management is already humongous and I still probably have double the amount left to do04:29
rm_workyeah04:30
rm_workit's not as compact as the websequencediagrams are...04:30
rm_worktons of extra space04:30
rm_worki may tweak with the styles a bit to see if i can cut down on the vertical padding04:30
bloganthe seqdiag's arent taking up much space, its the text im writing04:30
bloganyeah there's edge_height, length with adn all that04:30
rm_workspan_height04:31
rm_worki think04:31
rm_workdefault 40, maybe tune it down to like 1504:31
rm_worklol04:31
rm_workand might turn off the annoying activation line thing04:31
bloganour gerrit bot is gone again04:32
rm_workT_T04:32
rm_workthe one in THIS channel? yeah04:32
rm_worki noticed it didn't announce my new CR earlier04:32

rm_workwhat is yours04:32
rm_workah you reboot? :P04:33

sballeblogan Should I just abandon the https://review.openstack.org/#/c/127337/? and submit the sphinx stuff in a new gerrit review?14:00
ptoohillI know im not blogan, but if its easier that way it should be fine, otherwise updating the current one reduces the number of dead reviews to sift through. But thats just my opinion.14:02

codekobeHere is newer link on trove architecture20:38
codekobehttps://wiki.openstack.org/wiki/TroveArchitecture20:38
codekobeit is using a combination of methods here20:38
codekobebut essentially all communications is happening over a message bus20:40
rm_work"Conductor is similar to guest-agent in that it is a service that listens to a RabbitMQ topic."20:41
codekobequick notes: http://pastebin.com/4PnBSLxz20:41
codekobethere is an mq topic for each instance20:41
codekobepretty much eberything routes through the mq topic20:41
codekobemy pastebin has some links to different heartbeat code20:42
rm_workso pretty close to what we were discussing yesterday?20:42
codekobebut it essentially sends over a custom status for each db implementation20:42
codekobenot exactly like yesterday20:42
codekobehere are some of the differences20:42
codekobethe conductor doesnt take action on the out of date heartbeat20:42
rm_workyeah, i see that it adds to the DB and an agent acts on entries from the DB20:43
codekobethe conductor receives the heartbeat message over the instance's queue topic, and then persists that message to the datastore20:43
rm_workI am not sure if that is better or not20:43
codekobeand they have code `message_too_old`20:43
rm_workmaybe20:44
codekobethat examines messages on the topic to see if they are newer than the last one saved20:44
codekobesince messages on topic may be out of order20:44
codekobethe topic does not appear to have any kind of limit in length20:44
rm_workyeah, not clear on why the topic needs to store all messages, as opposed to just 1 like we were talking about20:44
codekobeas they use this same topic to communicate things about backups etc20:44
rm_workah20:45
codekobeso its used for more than just heartbeat20:45
rm_workare we planning to multi-purpose this mechanism?20:45
codekobewell, they also use the queue to execute tasks on the instances20:45
codekobeits all rpc based20:45
codekobeso initiating a backup or reconfiguration is all done by placing a task on the queue for the guest agent to pick up20:45
codekobeas opposed to having rest api on all agents20:46
codekobethe only real rest api is outward facing, and results in tasks being placed on the queue20:46
codekobethe taskmanager handles things like creating instances and attaching volumes, etc20:46
codekobewhile the conductor listens for agent status20:48
codekobeanother difference20:48
codekobewhich we may or may not like20:48
codekobeall communication TO the guest agent, like "make a backup" is done on the queue topic named after the instance_id20:48
rm_worki mean, that's kinda what i was thinking for queue topic naming20:49
codekobebut all communication FROM the guest_agent is placed on a single topic that the conductor listens on20:49
rm_workthe queue being 2-way is a little bit... >_>20:49
codekobehowever, the only info sent back to conductor is status type messages20:49
rm_workmakes some of the TLS security more complicated20:49
rm_workI'd still lean toward a single-purpose and highly optimized queue20:51
rm_workif queue is the way to go20:51
rm_work(only for the heartbeats)20:51

codekobeand should i put all options into a work in progress commit? to allow comments there?22:14
