Public bug reported:
The nova-manage db archive_deleted_rows command from Queens started
archiving instance_mappings and request_specs records when moving the
soft_deleted instances records to the shadow tables. However since the
api tables do not have the concept of soft deletion, the
instance_mapping and request_spec tables are linked to instances table
while doing the archival. Hence the --max_rows parameter that is
specified does not count/include the count of instance_mapping and
request_spec rows that are removed. So the --verbose output of the
command may not look right when the number are really large.
We need to either update the documentation saying two more records per
instance record will be archived or stop showing the output of the
archived tables from the API db. I guess same applies for the recent
patch where we archive instance_group_members.
