|
||||
## (Potential Backward Compatibility Break) Major improvements to Synapse workers
|
||||
|
||||
People who are interested in running a Synapse worker setup should know that **our Synapse worker implementation is much more powerful now**:
|
||||
|
||||
- we've added support for [Stream writers](#stream-writers-support)
|
||||
- we've added support for [multiple federation sender workers](#multiple-federation-sender-workers-support)
|
||||
- we've added support for [multiple pusher workers](#multiple-pusher-workers-support)
|
||||
- we've restored support for [`appservice` workers](#appservice-worker-support-is-back)
|
||||
- we've restored support for [`user_dir` workers](#user-directory-worker-support-is-back)
|
||||
- see the [Potential Backward Incompatibilities after these Synapse worker changes](#potential-backward-incompatibilities-after-these-synapse-worker-changes)
|
||||
|
||||
### Stream writers support
|
||||
|
|
@ -38,6 +40,25 @@ From now on, you can have as many as you want to help with your federation traff
|
|||
Until now, we only supported a single `pusher` worker (`matrix_synapse_workers_pusher_workers_count` could either be `0` or `1`).
|
||||
From now on, you can have as many as you want to help with pushing notifications out.
|
||||
|
||||
### Appservice worker support is back
|
||||
|
||||
We previously had an `appservice` worker type, which [Synapse deprecated in v1.59.0](https://github.com/matrix-org/synapse/blob/v1.59.0/docs/upgrade.md#deprecation-of-the-synapseappappservice-and-synapseappuser_dir-worker-application-types). So did we, at the time.
|
||||
|
||||
The new way to implement such workers is by using a `generic_worker` and dedicating it to the task of talking to Application Services.
|
||||
From now on, we have support for this.
|
||||
|
||||
With `matrix_synapse_workers_preset: one-of-each`, you'll get one `appserice` worker automatically.
|
||||
You can also control the `appserice` workers count with `matrix_synapse_workers_appserice_workers_count`. Only `0` or `1` workers of this type are supported by Synapse.
|
||||
|
||||
### User Directory worker support is back
|
||||
|
||||
We previously had a `user_dir` worker type, which [Synapse deprecated in v1.59.0](https://github.com/matrix-org/synapse/blob/v1.59.0/docs/upgrade.md#deprecation-of-the-synapseappappservice-and-synapseappuser_dir-worker-application-types). So did we, at the time.
|
||||
|
||||
The new way to implement such workers is by using a `generic_worker` and dedicating it to the task of serving the user directory.
|
||||
From now on, we have support for this.
|
||||
|
||||
With `matrix_synapse_workers_preset: one-of-each`, you'll get one `user_dir` worker automatically.
|
||||
You can also control the `user_dir` workers count with `matrix_synapse_workers_user_dir_workers_count`. Only `0` or `1` workers of this type are supported by Synapse.
|
||||
|
||||
### Potential Backward Incompatibilities after these Synapse worker changes
|
||||
|
||||
|
|
@ -45,6 +66,8 @@ Below we'll discuss **potential backward incompatibilities**.
|
|||
|
||||
- **Worker names** (container names, systemd services, worker configuration files) **have changed**. Workers are now labeled sequentially (e.g. `matrix-synapse-worker_generic_worker-18111` -> `matrix-synapse-worker-generic-0`). The playbook will handle these changes automatically.
|
||||
|
||||
- Due to increased worker types support above, people who use `matrix_synapse_workers_preset: one-of-each` should be aware that with these changes, **the playbook will deploy 8 additional workers** (6 stream writers, 1 `appservice` worker, 1 `user_dir` worker). This **may increase RAM/CPU usage**, etc. If you find your server struggling, consider disabling some workers with the appropriate `matrix_synapse_workers_*_workers_count` variables.
|
||||
|
||||
- **Metric endpoints have also changed** (`/metrics/synapse/worker/generic_worker-18111` -> `/metrics/synapse/worker/generic-worker-0`). If you're [collecting metrics to an external Prometheus server](docs/configuring-playbook-prometheus-grafana.md#collecting-metrics-to-an-external-prometheus-server), consider revisiting our [Collecting Synapse worker metrics to an external Prometheus server](docs/configuring-playbook-prometheus-grafana.md#collecting-synapse-worker-metrics-to-an-external-prometheus-server) docs and updating your Prometheus configuration. **If you're collecting metrics to the integrated Prometheus server** (not enabled by default), **your Prometheus configuration will be updated automatically**. Old data (from before this change) may stick around though.
|
||||
|
||||
- **the format of `matrix_synapse_workers_enabled_list` has changed**. You were never advised to use this variable for directly creating workers (we advise people to control workers using `matrix_synapse_workers_preset` or by tweaking `matrix_synapse_workers_*_workers_count` variables only), but some people may have started using the `matrix_synapse_workers_enabled_list` variable to gain more control over workers. If you're one of them, you'll need to adjust its value. See `roles/matrix-synapse/defaults/main.yml` for more information on the new format. The playbook will also do basic validation and complain if you got something wrong.
