Remote images are not cached or proxied right now as far as I know. Edit: seems I was wrong and there is some image caching happening. For sure for the small image thumbnails, but also sometimes for other pictures, but it seems very inconsistent.
Your growning pictrs directory might be also due to the extremely verbose default logging that Pictrs (and the Lemmy backend too btw) uses.
I'm just letting mine do whatever it wants, got plenty of local storage. If/when I have storage issues I'll add an s3 bucket, pretty easy to modify the entrypoint for pictrs to pass s3 connection info in the docker-compose deployment.
S3 support is a good thing, thanks for mentioning it.
IIRC, I've read comments elsewhere that pictrs caches for 6 months, but I can't independently verify. I hope this gets a broader answer because I'm still on the fence about getting an instance set up for myself and some small communities.
I believe the activity table in Postgres is retained for 6 months (although I’m purging mine daily) and the pict-rs cache is 168 hours (1 week).
I knew I read something was kept for 6 months ;)
Glad to see that even here, the best way to get the right answer on the internet is to provide a wrong one.
How do you purge daily? Also, does that delete any post history or anything in a similar vein?
I’m running the following SQL, although I’m not actually sure it’s as necessary since 0.18.3. It doesn’t delete any post history or anything.
DELETE FROM activity WHERE published < NOW() - INTERVAL '1 day';
