@lanodan Yeah... However, my database is over 100 GB these days.

@sjw Well I looked at the migration again and it's not that surprising given a very active instance.

Can you file an issue?

@lanodan For what exactly? Just "this migration takes too long!"? I don't really know if it's much of an issue. Maybe add a warning or something but still kinda unavoidable assuming it's actually working.

@sjw Well it’s just that I’ll probably forget about it in few minutes and you probably have more information than me for this.

Also can you do something like:

SELECT count(id) FROM notifications;

or the size of notifications with a \d+ so we have an idea of the size of your table.

@lanodan Got 846638.
Output of \d+ notifications:

@sjw I meant \d+ alone but the count should be enough.

@lanodan Oh! It's 130 MB

@sjw Holy shit…

@lanodan I'm wondering if there's something wrong... Surely it shouldn't take this long should it?

@sjw

I'm quite bad at knowing how much a SQL command takes, I often try normal programming modifications and then EXPLAIN.

@lanodan Well, postgres isn't really using any CPU.

@sjw Does this htop has detailed CPU time? (so you can see iowait)

@lanodan Yeah. I've also got netdata running on the server

@sjw Might explain few things…

@lanodan I think that's just kinda incoming federation while it's running
https://git.pleroma.social/pleroma/pleroma/-/issues/1716

@lanodan Migration just finished.

@sjw yeah, saw it, OOF at the time it took.

@lanodan Looks like 20200527163635_delete_notifications_from_invisible_users is going to be another 20200602125218_backfill_notification_types

@sjw Ouch, could you report it? (I moved my Sunday to today so dayoff)

@lanodan I'll let it go for at least 30 minutes to be sure it's a long boi

@lanodan Nevermind. Only took 08m34s
