Thanks to [Aine](https://gitlab.com/etke.cc) of [etke.cc](https://etke.cc/), the playbook can now set up [rust-synapse-compress-state](https://github.com/matrix-org/rust-synapse-compress-state)'s `synapse_auto_compressor` tool to run periodically.
If enabled, `synapse_auto_compressor` runs on a schedule and compresses your Synapse database's `state_groups` table. It was possible to run `rust-synapse-compress-state` manually via the playbook even before - see [Compressing state with rust-synapse-compress-state](docs/maintenance-synapse.md#compressing-state-with-rust-synapse-compress-state). However, using `synapse_auto_compressor` is better, because:
- it runs on a more up-to-date version of `rust-synapse-compress-state`
- it's a set-it-and-forget-it tool that you can enable and never have to deal with manual compression anymore
This tool needs to be enabled manually, for now. In the future, we're considering enabling it by default for all Synapse installations.
See our [Setting up synapse-auto-compressor](docs/configuring-playbook-synapse-auto-compressor.md) documentation to get started.

[rust-synapse-compress-state](https://github.com/matrix-org/rust-synapse-compress-state) can be used to optimize some `_state` tables used by Synapse. If your server participates in large rooms this is the most effective way to reduce the size of your database.
This tool should be safe to use (even when Synapse is running), but it's always a good idea to [make Postgres backups](./maintenance-postgres.md#backing-up-postgresql) first.
**Note**: besides running the `rust-synapse-compress-state` tool manually, you can also enable its `synapse-auto-compressor` tool by [Setting up synapse-auto-compressor](configuring-playbook-synapse-auto-compressor.md). The automatic tool will run on a schedule every day and you won't have to compress state manually ever again.
