+# Room admins and mods can define a retention period for their rooms using the

+#
+# If this feature is enabled, Synapse will regularly look for and purge events
+# which are older than the room's maximum retention period. Synapse will also
+# filter events received over federation so that events that should have been
+# purged are ignored and not stored again.

+ # 'm.room.retention' event which features a 'min_lifetime' or a 'max_lifetime'

+
+ # Server admins can define the settings of the background jobs purging the
+ # events which lifetime has expired under the 'purge_jobs' section.
+ #
+ # If no configuration is provided, a single job will be set up to delete expired
+ # events in every room daily.
+ #
+ # Each job's configuration defines which range of message lifetimes the job
+ # takes care of. For example, if 'shortest_max_lifetime' is '2d' and
+ # 'longest_max_lifetime' is '3d', the job will handle purging expired events in
+ # rooms whose state defines a 'max_lifetime' that's both higher than 2 days, and
+ # lower than or equal to 3 days. Both the minimum and the maximum value of a
+ # range are optional, e.g. a job with no 'shortest_max_lifetime' and a
+ # 'longest_max_lifetime' of '3d' will handle every room with a retention policy
+ # which 'max_lifetime' is lower than or equal to three days.
+ #
+ # The rationale for this per-job configuration is that some rooms might have a
+ # retention policy with a low 'max_lifetime', where history needs to be purged
+ # of outdated messages on a very frequent basis (e.g. every 5min), but not want
+ # that purge to be performed by a job that's iterating over every room it knows,
