To other Mastodon sysadmins: Check what pg_repack can do for you, especially if your server has been around for a really long time. PostgreSQL indexes get bloated over time and VACUUM does nothing about it. pg_repack can re-build indexes without downtime.
@Gargron How big are the database and media directories in total? What size of server is required to host a community like mastodon.social?
@Gargron at work we have an intense INSERT/UPDATE’ activity on the core DB so we must rebuild indexes every week to ensure performance and mitigate storage waste.
@gargron "Eugen used this one weird trick to reduce the size of his PostgreSQL database by 40 GB! Hosting vendors hate him!!"
@Gargron how I wish I understood what you are saying! How glad I am that you who do use your knowledge to help us have a voice!
