Purge History API

The purge history API allows server admins to purge historic events from their database, reclaiming disk space.

Depending on the amount of history being purged a call to the API may take several minutes or longer. During this period users will not be able to paginate further back in the room from the point being purged from.

The API is:

POST /_matrix/client/r0/admin/purge_history/<room_id>[/<event_id>]

including an access_token of a server admin.

By default, events sent by local users are not deleted, as they may represent the only copies of this content in existence. (Events sent by remote users are deleted, and room state data before the cutoff is always removed).

To delete local events as well, set delete_local_events in the body:

{
    "delete_local_events": true
}

The caller must specify the point in the room to purge up to. This can be specified by including an event_id in the URI, or by setting a purge_up_to_event_id or purge_up_to_ts in the request body. If an event id is given, that event (and others at the same graph depth) will be retained. If purge_up_to_ts is given, it should be a timestamp since the unix epoch, in milliseconds.
