Heya,
Review https://review.openstack.org/#/c/135644/4 proposes the addition
of a new database for our improved implementation of cells in Nova.
However, there's an outstanding question about how to handle soft
delete of rows -- we believe that we need to soft delete for forensic
purposes.
This is a new database, so its our big chance to get this right. So,
ideas welcome...
Some initial proposals:
- we do what we do in the current nova database -- we have a deleted
column, and we set it to true when we delete the instance.
- we have shadow tables and we move delete rows to a shadow table.
- something else super clever I haven't thought of.
Ideas?
