sorrison | Hi 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 |

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

sorrison | Well it essentially has with the instance upgrade | 07:38 |
sorrison | I think the change in how upgrade works needs to be given more thought. | 07:39 |
sorrison | The 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 them | 07:40 |
sorrison | this is a killer feature in trove. I don't see the new instance rebuild method being that useful | 07:41 |
sorrison | We 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 upgrade | 07:42 |
sorrison | We 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 them | 07:42 |
sorrison | This is extremely useful | 07:42 |

lxkong | The 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 |
lxkong | After using docker image, it's easier to upgrade datastore for the user, doesn't involve cloud operator any more. | 22:49 |
lxkong | It just becomes the cloud operator's responsibility to upgrade OS and trove-guestagent (by using rebuild API). | 22:50 |
lxkong | which is mroe reasonable | 22:50 |

sorrison | yeah 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 them | 23:21 |
