I'll be working on upgrading aussie.zone to lemmy 0.19.6 today. All going well disruption will be brief, but there may be some performance issues related to back end DB changes required as part of the upgrade.

I'll unpin this once complete.

0.19.6 includes many fixes and new features... the biggest for me is "Parallel federation sending". This allows instance admins to send multiple federated activities in parrallel, rather than singly in series.

Not that its a real issue for other admins with activities from AZ, but I have set this to 2 for our outgoing activities.

Hopefully the lemmy.world admins will upgrade to 0.19.6 soon and do the same, this should allow AZ to catch up with activities from LW, and stay up to date. Over time as activities from LW have decreased we've "caught up" to within ~5 days of live. Doubling the rate that LW sends activities to AZ will help massively.

It doesn't appear to need lemmy.world to upgrade! https://aussie.zone/post/15206144/13130297

There's a lemmy.world user commenting in a current local thread. I am very happy!

[–] Nath@aussie.zone 1 points 4 days ago* (last edited 4 days ago) (1 children)

Maybe not: No major difference on our Federation Health with lemmy.world.

[–] lodion@aussie.zone 1 points 4 days ago

Yeah... I understood outgoing federation of activities was linear FIFO. The new feature in 0.19.6 allows N instances of linear FIFO, with related activities federated in sequence.

Our outgoing activities go out very quickly, aussie.zone has a very low activity rate so remote instances don't tend to get behind at all.

How a LW user replied to a current AZ post and had it show up here in a decent timeframe is a mystery to me, seeing as they're still running their custom version of 0.19.3

[–] lodion@aussie.zone 1 points 4 days ago

I can only guess the order activities are federated in is random? Which doesn't make much sense.

[–] ryannathans@aussie.zone 3 points 6 days ago (1 children)

I saw that too! Keen. Any idea what degree of parallelism it is?

[–] lodion@aussie.zone 3 points 6 days ago (1 children)

It's configurable... defaults to 1 thread. Given we're slowly catching up with LW during low activity parts of the day, I think 2 should be enough.

[–] ryannathans@aussie.zone 3 points 6 days ago (1 children)

I thought it'd be asynchronous, not threaded.

Ah well as long as it works

[–] Zagorath@aussie.zone 1 points 6 days ago

Yeah it's kinda disappointing from a technical perspective, but I guess threading it is easier. Less need to worry about conflicts like replies not arriving before the comment they're replying to, or one edit arriving after a later edit.

nice work 💪

[–] Blaze@feddit.org 1 points 4 days ago

Well done

Ok... DB migration was an offline my migration, my bad. Took longer I expected... but we're back in action 🤓

Thanks for your service @lodion
