These mix tasks can take a long time to complete. Many of them were written to address specific database issues that happened because of bugs in migrations or other specific scenarios. Do not run these tasks "just in case" if everything is fine your instance.
Replaces embedded objects with references to them in the `objects` table. Only needs to be ran once if the instance was created before Pleroma 1.0.5. The reason why this is not a migration is because it could significantly increase the database size after being ran, however after this `VACUUM FULL` will be able to reclaim about 20% (really depends on what is in the database, your mileage may vary) of the db size before the migration.
This will prune remote posts older than 90 days (configurable with [`config :pleroma, :instance, remote_post_retention_days`](../../configuration/cheatsheet.md#instance)) from the database. Pruned posts may be refetched in some cases.
The disk space will only be reclaimed after `VACUUM FULL`. You may run out of disk space during the execution of the task or vacuuming if you don't have about 1/3rds of the database size free.
-`--keep-threads` - don't prune posts when they are part of a thread where at least one post has seen local interaction (e.g. one of the posts is a local post, or is favourited by a local user, or has been repeated by a local user...)
-`--keep-non-public` - keep non-public posts like DM's and followers-only, even if they are remote
Change `default_text_search_config` for database and (if necessary) text_search_config used in index, then rebuild index (it may take time).
