sorrisonHi lxkong, so when a user does an instance upgrade now the version of the DB is upgraded but the underlying image and the version of trove-guestagent stay the same?03:38

lxkongsorrison: yes, the instance upgrade only means the db service upgrade, not os neither guest agent.06:20
lxkongsorrison: trove has never provided os and guest agnet upgrade function before06:21
lxkonguntil 'rebuild' function was implemented in Victoria.06:21

sorrisonWell it essentially has with the instance upgrade07:38
sorrisonI think the change in how upgrade works needs to be given more thought.07:39
sorrisonThe way upgrade has worked up until ussuri is better I think as it allows operators to push out new versions of the DB, the operating system and the trove guest agent and importantly allow the user to do that at a time that suites them07:40
sorrisonthis is a killer feature in trove. I don't see the new instance rebuild method being that useful07:41
sorrisonWe have run trove since liberty and now on ussuri and we haven't once had an outage on users trove instances that wasn't initiated by the user themselves by doing an upgrade07:42
sorrisonWe send them a notification and alert them they need to do the upgrade by a certain time (usually a few months) else we will do it for them07:42
sorrisonThis is extremely  useful07:42

lxkongThe OS and trove-guestagent upgrade process should be transparent to the end users. You can do that before because when upgrading database you need to re-build the guest image.22:49
lxkongAfter using docker image, it's easier to upgrade datastore for the user, doesn't involve cloud operator any more.22:49
lxkongIt just becomes the cloud operator's responsibility to upgrade OS and trove-guestagent (by using rebuild API).22:50
lxkongwhich is mroe reasonable22:50

sorrisonyeah that is bad, we don't want to have to upgrade all out users DBs ourselves, puts more work on us and also means users can't do it when it suites them23:21
