+ # If no configuration is provided, a single job will be set up to delete expired

+ #
+ # 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+ # of outdated messages on a very frequent basis (e.g. every 5min), but not want
