+You can configure the Overlord to delete indexer task log metadata and the 
indexer task logs from local disk or from cloud storage.  The cleanup includes 
the `druid_tasks` and `druid_tasklogs` tables in the metadata database, and the 
task logs in deep storage.  (Note that `druid_tasklogs` is no longer used and 
will already be empty, unless the druid version is older.) 

Review Comment:
   Two follow up questions:
   1. Do you know what older version uses `druid_tasklogs`? Wondering if we can 
say something like "unless the Druid version is XX or older."
   2. Should the table be called `druid_taskLog`? That's what's listed in the 
configuration table:
