!!! danger 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.
=== “OTP”
```sh
./bin/pleroma_ctl database remove_embedded_objects [option ...]
```
=== “From Source”
```sh
mix pleroma.database remove_embedded_objects [option ...]
```
--vacuum
- run VACUUM FULL
after the embedded objects are replaced with their referencesThis will prune remote posts older than 90 days (configurable with config :pleroma, :instance, remote_post_retention_days
) from the database, they will be refetched from source when accessed.
!!! danger
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.
=== “OTP”
```sh
./bin/pleroma_ctl database prune_objects [option ...]
```
=== “From Source”
```sh
mix pleroma.database prune_objects [option ...]
```
--vacuum
- run VACUUM FULL
after the objects are prunedCan be safely re-run
=== “OTP”
```sh
./bin/pleroma_ctl database bump_all_conversations
```
=== “From Source”
```sh
mix pleroma.database bump_all_conversations
```
=== “OTP”
```sh
./bin/pleroma_ctl database update_users_following_followers_counts
```
=== “From Source”
```sh
mix pleroma.database update_users_following_followers_counts
```
=== “OTP”
```sh
./bin/pleroma_ctl database fix_likes_collections
```
=== “From Source”
```sh
mix pleroma.database fix_likes_collections
```
Running an analyze
vacuum job can improve performance by updating statistics used by the query planner. It is safe to cancel this.
=== “OTP”
```sh
./bin/pleroma_ctl database vacuum analyze
```
=== “From Source”
```sh
mix pleroma.database vacuum analyze
```
Running a full
vacuum job rebuilds your entire database by reading all of the data and rewriting it into smaller
and more compact files with an optimized layout. This process will take a long time and use additional disk space as
it builds the files side-by-side the existing database files. It can make your database faster and use less disk space,
but should only be run if necessary. It is safe to cancel this.
=== “OTP”
```sh
./bin/pleroma_ctl database vacuum full
```
=== “From Source”
```sh
mix pleroma.database vacuum full
```
=== “OTP”
```sh
./bin/pleroma_ctl database ensure_expiration
```
=== “From Source”
```sh
mix pleroma.database ensure_expiration
```
Change default_text_search_config
for database and (if necessary) text_search_config used in index, then rebuild index (it may take time).
=== “OTP”
```sh
./bin/pleroma_ctl database set_text_search_config english
```
=== “From Source”
```sh
mix pleroma.database set_text_search_config english
```
