Maintain the prefix_itr between calls to SnapMapper::get_next_objects_to_trim() to prevent searching depleted prefixes. We got 8 distinct hash prefixes used for searching objects owned by a given PG. On each call to SnapMapper::get_next_objects_to_trim() we start from the first prefix even after all objects mapped to it were depleted. This means that we will be searching for 1 non-existing prefix after the first prefix was depleted, 2 after the first two prefixes were depleted... and so on until we will search 7 non-existing prefixes after the first 7 prefixes were depleted. This is a performance improvement PR only! It maintains the existing behavior and does not try to fix/change any of the TRIM logic. I added an extra step after the last object is trimmed doing a full scan of the DB and only if no object was found it will return ENOENT. This should make the new code no-worse than existing code which returns ENOENT after a full scan found no object. It should not impact performance in real life snaps as it should only happen once per-snap. added snap-mapper tests to rados-test-suite disabled osd_debug_trim_objects when running (SnapMapperTest, prefix_itr) to prevent asserts(as this code does illegal inserts into DELETED snaps) Code beautifing Signed-off-by: Gabriel BenHanokh <gbenhano@redhat.com> |
