The implementation as far as I understand it is plain stupid. It prevents small instances from participating at any significant scale and seems happy to just drop data over the wire without reconciling. Seriously amateurish.
I'm not sure about the data being dropped, my instance was misconfigured for a day or two, and as soon as I fixed it, the data came right in. Instances repeatedly trying to push data to my instance is what clued me in that something was missing from my NGINX config. It backfilled pretty fast.
Although I wouldn't mind if there was a fallback pull mechanism to remediate failed pushes.
Interesting. Curious if you have a better understanding of ActivePub - do you happen to know if the protocol guarantees synchonicity and what mechanism guarantees it?
I don't, really going off on ~1 week of running my essentially single user instance and watching it do its thing. I need to read the spec and experiment with it when I have some more free time.
Pure speculation but my guess would be that the servers are expected to retry for a certain amount of time. I know there's been some tickets opened for some big instances going out of sync with eachother and fixes being worked on to address those. I don't know if it only fixes it forward or if that also backfills.
Also nothing preventing Lemmy from implementing a fallback way of doing a resync if it detects drift. "Hey lemm.ee, I lost everything since an hour ago, backfill please".
Yeah, or batching changes and confirming receipt with a hash. From what I've been reading, the design seems a little janky.
