Thank you Dmitriy! I am a bit surprised. I'd expect records for deleted resource
to be cleaned up by some retention policy.

Will need to make sure such clean-up to be taken care of by daily operation.
BTW, is it mentioned in any doc? I probably missed it.

Hi Tony,

There is no default retention policy defined.
To clean up such records for cinder you can run command
cinder-manage db purge <days to retain>

For nova it's a bit more complicated as first you would archive these records and only then purge them from shadow tables. This is done with nova-manage command.
You can check docs regarding it's usage:

I see the record for deleted resource stay in database.
What's the retention policy for those records?
Is it configurable?
Any manual cleanup is required?
