+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:
   ```suggestion
   You can configure the Overlord to periodically delete indexer task logs and associated metadata. During cleanup, the Overlord removes the following:
   * Indexer task logs from local disk or cloud storage.
   * Indexer task log metadata from the `druid_tasks` and `druid_taskLog` tables in [metadata storage](../configuration/index.md#metadata-storage). Note that Druid no longer uses the `druid_tasklogs` table, which should be empty in new versions of Druid.
   ```
