Heat-manage helps manage Heat specific database operations. The associated database should be periodically purged to save space. The following should be setup as a cron job on the servers where the heat service is running at /etc/cron.weekly/local-cleanup-heat with the following content:

  #!/bin/bash
  su heat -s /bin/bash -c "/usr/bin/heat-manage purge_deleted -g days 14" || :
  

nova-manage db archive_deleted_rows command will move deleted rows from production tables to shadow tables. Including --until-complete will make the command run continuously until all deleted rows are archived. It is recommended to setup this task as /etc/cron.weekly/local-cleanup-nova on the servers where the nova service is running, with the following content:

  #!/bin/bash
  su nova -s /bin/bash -c "/usr/bin/nova-manage db archive_deleted_rows --until-complete" || :
