## Workers ##
|
||||
Configuration options related to workers.
|
||||
## Coordinating workers
|
||||
Configuration options related to workers which belong in the main config file
|
||||
(usually called `homeserver.yaml`).
|
||||
A Synapse deployment can scale horizontally by running multiple Synapse processes
|
||||
called _workers_. Incoming requests are distributed between workers to handle higher
|
||||
loads. Some workers are privileged and can accept requests from other workers.
|
||||
|
||||
As a result, the worker configuration is divided into two parts.
|
||||
|
||||
1. The first part (in this section of the manual) defines which shardable tasks
|
||||
are delegated to privileged workers. This allows unprivileged workers to make
|
||||
request a privileged worker to act on their behalf.
|
||||
1. [The second part](#individual-worker-configuration)
|
||||
controls the behaviour of individual workers in isolation.
|
||||
|
||||
For guidance on setting up workers, see the [worker documentation](../../workers.md).
|
||||
|
||||

|
||||
### `worker_replication_secret`
|
||||
|
||||
A shared secret used by the replication APIs on the main process to authenticate
|
||||
HTTP requests from workers.
|
||||
|
||||
The default, this value is omitted (equivalently `null`), which means that
|
||||
traffic between the workers and the main process is not authenticated.
|
||||
|
||||
Example configuration:
|
||||
```yaml
|
||||
worker_replication_secret: "secret_secret"
|
||||
```
|
||||
---
|
||||
### `start_pushers`
|
||||
|
||||
Controls sending of push notifications on the main process. Set to `false`
|
||||
if using a [pusher worker](../../workers.md#synapseapppusher). Defaults to `true`.
|
||||
|
||||
Example configuration:
|
||||
```yaml
|
||||
start_pushers: false
|
||||
```
|
||||
---
|
||||
### `pusher_instances`
|
||||
|
||||
It is possible to run multiple [pusher workers](../../workers.md#synapseapppusher),
|
||||
in which case the work is balanced across them. Use this setting to list the pushers by
|
||||
[`worker_name`](#worker_name). Ensure the main process and all pusher workers are
|
||||
restarted after changing this option.
|
||||
|
||||
If no or only one pusher worker is configured, this setting is not necessary.
|
||||
The main process will send out push notifications by default if you do not disable
|
||||
it by setting [`start_pushers: false`](#start_pushers).
|
||||
|
||||
Example configuration:
|
||||
```yaml
|
||||
start_pushers: false

pusher_instances:
|
||||
- pusher_worker1
|
||||

### `send_federation`

||||

||||
Set to false if using a federation sender worker. Defaults to true.

||||
Set to `false` if using a [federation sender worker](../../workers.md#synapseappfederation_sender).

|
||||
### `worker_app`
|
||||
|
||||
The type of worker. The currently available worker applications are listed
|
||||
in [worker documentation](../../workers.md#available-worker-applications).
|
||||
|
||||
The most common worker is the
|
||||
[`synapse.app.generic_worker`](../../workers.md#synapseappgeneric_worker).
|
||||
|
||||
Example configuration:
|
||||
```yaml
|
||||
worker_app: synapse.app.generic_worker
|
||||
```
|
||||
---
|
||||
### `worker_name`
|
||||
|
||||
A unique name for the worker. The worker needs a name to be addressed in
|
||||
further parameters and identification in log files. We strongly recommend
|
||||
giving each worker a unique `worker_name`.
|
||||
|
||||
Example configuration:
|
||||
```yaml
|
||||
worker_name: generic_worker1
|
||||
```
|
||||
---
|
||||
### `worker_replication_host`
|
||||
|
||||
The HTTP replication endpoint that it should talk to on the main Synapse process.
|
||||
The main Synapse process defines this with a `replication` resource in
|
||||
[`listeners` option](#listeners).
|
||||
|
||||
Example configuration:
|
||||
```yaml
|
||||
worker_replication_host: 127.0.0.1
|
||||
```
|
||||
---
|
||||
### `worker_replication_http_port`
|
||||
|
||||
The HTTP replication port that it should talk to on the main Synapse process.
|
||||
The main Synapse process defines this with a `replication` resource in
|
||||
[`listeners` option](#listeners).
|
||||
|
||||
Example configuration:
|
||||
```yaml
|
||||
worker_replication_http_port: 9093
|
||||
```
|
||||
---
|
||||
### `worker_listeners`
|
||||
|
||||
A worker can handle HTTP requests. To do so, a `worker_listeners` option
|
||||
must be declared, in the same way as the [`listeners` option](#listeners)
|
||||
in the shared config.
|
||||
|
||||
Workers declared in [`stream_writers`](#stream_writers) will need to include a
|
||||
`replication` listener here, in order to accept internal HTTP requests from
|
||||
other workers.
|
||||
|
||||
Example configuration:
|
||||
```yaml
|
||||
worker_listeners:
|
||||
- type: http
|
||||
port: 8083
|
||||
resources:
|
||||
- names: [client, federation]
|
||||
```
|
||||
---
|
||||
### `worker_daemonize`
|
||||
|
||||
Specifies whether the worker should be started as a daemon process.
|
||||
If Synapse is being managed by [systemd](../../systemd-with-workers/README.md), this option
|
||||
must be omitted or set to `false`.
|
||||
|
||||
Defaults to `false`.
|
||||
|
||||
Example configuration:
|
||||
```yaml
|
||||
worker_daemonize: true
|
||||
```
|
||||
---
|
||||
### `worker_pid_file`
|
||||
|
||||
When running a worker as a daemon, we need a place to store the
|
||||
[PID](https://en.wikipedia.org/wiki/Process_identifier) of the worker.
|
||||
This option defines the location of that "pid file".
|
||||
|
||||
This option is required if `worker_daemonize` is `true` and ignored
|
||||
otherwise. It has no default.
|
||||
|
||||
See also the [`pid_file` option](#pid_file) option for the main Synapse process.
|
||||
|
||||
Example configuration:
|
||||
```yaml
|
||||
worker_pid_file: DATADIR/generic_worker1.pid
|
||||
```
|
||||
---
|
||||
### `worker_log_config`
|
||||
|
||||
This option specifies a yaml python logging config file as described
|
||||
[here](https://docs.python.org/3/library/logging.config.html#configuration-dictionary-schema).
|
||||
See also the [`log_config` option](#log_config) option for the main Synapse process.

Normally, only a couple of changes are needed to make an existing configuration

file suitable for use with workers. First, you need to enable an "HTTP replication

The `events` stream experimentally supports having multiple writer workers, where load
|
||||
is sharded between them by room ID. Each writer is called an _event persister_. They are
|
||||
responsible for
|
||||
- receiving new events,
|
||||
- linking them to those already in the room [DAG](development/room-dag-concepts.md),
|

- persisting them to the DB, and finally

- updating the events stream.

adding or removing event persisters.

An `event_persister` should not be mistaken for an `event_creator`.
