 Scaling synapse via workers
----------------------------
+===========================
 
 Synapse has experimental support for splitting out functionality into
 multiple separate python processes, helping greatly with scalability.  These
 processes are called 'workers', and are (eventually) intended to scale
 horizontally independently.
 
+All of the below is highly experimental and subject to change as Synapse evolves,

+Configuration
+-------------
+
+To make effective use of the workers, you will need to configure an HTTP
+reverse-proxy such as nginx or haproxy, which will direct incoming requests to
+the correct worker, or to the main synapse instance. Note that this includes
+requests made to the federation port. The caveats regarding running a
+reverse-proxy on the federation port still apply (see
+https://github.com/matrix-org/synapse/blob/master/README.rst#reverse-proxying-the-federation-port).

- * synapse.app.federation_reader - handles receiving federation traffic (including public_rooms API)
- * synapse.app.media_repository - handles the media repository.
- * synapse.app.client_reader - handles client API endpoints like /publicRooms
 
 Each worker configuration file inherits the configuration of the main homeserver
 configuration file.  You can then override configuration specific to that worker,
 e.g. the HTTP listener that it provides (if any); logging configuration; etc.
 You should minimise the number of overrides though to maintain a usable config.

+-----------------------------
+
+``synapse.app.pusher``
+~~~~~~~~~~~~~~~~~~~~~~
+
+Handles sending push notifications to sygnal and email. Doesn't handle any
+REST endpoints itself, but you should set ``start_pushers: False`` in the
+shared configuration file to stop the main synapse sending these notifications.
+
+Note this worker cannot be load-balanced: only one instance should be active.
+
+``synapse.app.synchrotron``
+~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+The synchrotron handles ``sync`` requests from clients. In particular, it can
+handle REST endpoints matching the following regular expressions::
+
+    ^/_matrix/client/(v2_alpha|r0)/sync$
+    ^/_matrix/client/(api/v1|v2_alpha|r0)/events$
+    ^/_matrix/client/(api/v1|r0)/initialSync$
+    ^/_matrix/client/(api/v1|r0)/rooms/[^/]+/initialSync$
+
+The above endpoints should all be routed to the synchrotron worker by the
+reverse-proxy configuration.
+
+It is possible to run multiple instances of the synchrotron to scale
+horizontally. In this case the reverse-proxy should be configured to
+load-balance across the instances, though it will be more efficient if all
+requests from a particular user are routed to a single instance. Extracting
+a userid from the access token is currently left as an exercise for the reader.
+
+``synapse.app.appservice``
+~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Handles sending output traffic to Application Services. Doesn't handle any
+REST endpoints itself, but you should set ``notify_appservices: False`` in the
+shared configuration file to stop the main synapse sending these notifications.
+
+Note this worker cannot be load-balanced: only one instance should be active.
+
+``synapse.app.federation_reader``
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Handles a subset of federation endpoints. In particular, it can handle REST
+endpoints matching the following regular expressions::
+
+    ^/_matrix/federation/v1/event/
+    ^/_matrix/federation/v1/state/
+    ^/_matrix/federation/v1/state_ids/
+    ^/_matrix/federation/v1/backfill/
+    ^/_matrix/federation/v1/get_missing_events/
+    ^/_matrix/federation/v1/publicRooms
+
+The above endpoints should all be routed to the federation_reader worker by the
+reverse-proxy configuration.
+
+``synapse.app.federation_sender``
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Handles sending federation traffic to other servers. Doesn't handle any
+REST endpoints itself, but you should set ``send_federation: False`` in the
+shared configuration file to stop the main synapse sending this traffic.
+
+Note this worker cannot be load-balanced: only one instance should be active.
+
+``synapse.app.media_repository``
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Handles the media repository. It can handle all endpoints starting with::
+
+    /_matrix/media/
+
+You should also set ``enable_media_repo: False`` in the shared configuration
+file to stop the main synapse running background jobs related to managing the
+media repository.
+
+Note this worker cannot be load-balanced: only one instance should be active.
+
+``synapse.app.client_reader``
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Handles client API endpoints. It can handle REST endpoints matching the
+following regular expressions::
+
+    ^/_matrix/client/(api/v1|r0|unstable)/publicRooms$
+
+``synapse.app.user_dir``
+~~~~~~~~~~~~~~~~~~~~~~~~
+
+Handles searches in the user directory. It can handle REST endpoints matching
+the following regular expressions::
+
+    ^/_matrix/client/(api/v1|r0|unstable)/user_directory/search$
+
+``synapse.app.frontend_proxy``
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Proxies some frequently-requested client endpoints to add caching and remove
+load from the main synapse. It can handle REST endpoints matching the following
+regular expressions::
+
+    ^/_matrix/client/(api/v1|r0|unstable)/keys/upload
+
+It will proxy any requests it cannot handle to the main synapse instance. It
+must therefore be configured with the location of the main instance, via
+the ``worker_main_http_uri`` setting in the frontend_proxy worker configuration
+file. For example::
+
+    worker_main_http_uri: http://127.0.0.1:8008
