The
activitytable is also used to deduplicate incoming federation data, so instead of truncating it, I'd suggest deleting rows after a certain amount of time.For my personal instance, I set up a cron to delete entries older than 3 days, and my db is only ~500MB with a few weeks of content! I also haven't seen any duplicated posts or comments. Even with Lemmy's retries, 3 days seems to be long enough before dropping rows from that table.
Could you share the cron/script you use to do this? I'm interested in hosting my own Lemmy at some point, and having a script for that cleanup would be hugely helpful for me.
Definitely! I'm hosting in Kubernetes so I won't post the full thing, but here's the actual command that I run hourly. Make sure to replace the values for
database,username, andpassword.Awesome, that was just as straightforward as I was hoping it was, thanks! I am more familiar with MySQL as I haven't used Postgres a ton but SQL is SQL after all lol
You're welcome! Makes sense. They're somehow so similar yet so different lol
Ah! I didn't know exactly what was being used for.
Yeah, then it can only be trimmed, not truncated.
This is a great idea, thank you!
I'll have to try this later. Thanks for the tip!
Can you help me set this up also or share the script I would run to do this? Many thanks.
Sure! My script will look a little different since I'm hosting Lemmy in Kubernetes, but basically you will want to run the following command hourly. Make sure to replace the values for
database,username, andpassword.Thank you :)
You're welcome!
Hi - can you help me set this up or share the script that you use to do this? Many thanks :)
