Just went through an upgrade to this branch on dublin. After the mupdate, while Nexus is blocked waiting for schema migrations, we had a few collections from before the update: After performing the schema migration, all of them were removed (as expected). About 2 minutes later, the first post-upgrade collection showed up. (I think from watching Nexus logs, most of that 2 minutes was in Nexus's backoff waiting for the schema migration.) This is what the |

Thoughts on deriving this?

Hmm, that would require Generation to impl Default, which it currently does not. I can't think of a reason why it shouldn't, but will ask around.

This generated a lot of discussion. 😅 Generation not implementing Default is intentional, so I'll leave this as-is.

This is absolutely incredible work.
Accepting modulo a few comments.

Does this need to set a default value (not-yet-run?) in this migration, and then remove the default in a future one?

I was worried it might, but it doesn't, because we've explicitly removed all the rows from inv_sled_agent in up01.sql.

I guess these are just copied from inv_omicron_zone_nic etc?

Yes: a few of these "new" tables are really the old table with a new column, except that new column is part of the primary key. I think it's easier to reason about the migration as "drop the table, recreate the new table" instead of having to deal with migrating the primary key indices.

The primary change here is replacing these inventory fields (a subset of
OmicronSledConfig):with these:
Once #8064 lands, all three of these will be filled in meaningfully; as of this PR, only
ledgered_sled_configis populated. (reconciler_statusis alwaysNotYetRunandlast_reconciliationis alwaysNone, since there is no reconciler yet.) The rest of the changes are all fallout from changing inventory:omdbprintingledgered_sled_configfor now, but will need to be updated on [sled-agent] Integrate config-reconciler #8064 once other fields are populatedomicron_zonesto a fullOmicronSledConfig. The first few schema migrations take care of this.Before merging I'll go through an upgrade on a racklette and confirm things come back up okay after the schema migration blows away all the pre-update inventory collections. (We think this is fine, but it'd be good to confirm.) But I think this is close enough that it's reviewable.
Couple other minor changes that came along for the ride:
inv_sled_omicron_zonesis gone now)image_sourcecolumns to the inventory zone config table, so we don't loseImageSource::Artifact { hash }values reported by sled-agent)
