Public bug reported: nova.task_log database records are related to the server usage audit log API [1] which is dependent on the [DEFAULT]/instance_usage_audit config option being set to True (it defaults to False). Enablement of the config option causes nova-compute to emit notifications which are consumed by OpenStack Telemetry. When the config option is enabled, records will be periodically created in the nova.task_log table. And there is no cleanup of the records in nova.
I started a ML thread about the server usage audit log API awhile back [2] and the conclusion was that deprecating or removing the API isn't practical as there are systems in the wild still using it, so the best action to take for now is to create a nova-manage command for cleaning up old nova.task_log records. I brought up the proposal in a nova meeting [3] and in the nova channel [4] and the consensus was to treat it as a Wishlist bug so that it can be backported upstream. So this is a bug for the work to add a new 'nova-manage db purge_task_log' command that offers a --before <datetime> option.
