The playbook can install and configure synapse_auto_compressor for you.
It’s a cli tool that automatically compresses state_groups database table in background.
See the project’s documentation to learn what it does and why it might be useful to you.
Add the following configuration to your inventory/host_vars/matrix.DOMAIN/vars.yml file:
matrix_synapse_auto_compressor_enabled: true
After configuring the playbook, run the installation command again:
ansible-playbook -i inventory/hosts setup.yml --tags=setup-all,start
After installation, synapse_auto_compressor will run automatically every day by the defined schedule
For testing your setup it can be helpful to not wait until 00:00. If you want to run the tool immediately, log onto the server
and run systemctl start matrix-synapse-auto-compressor. This will not return until the run is done, so possibly a long time.
Consider using tmux if your SSH connection is unstable.
