Description

Metadata entries and their versions are being archived in the metadata_heap pool (.rgw.meta), but nothing is actually consuming this data. This archival should be made optional so that users can avoid paying the cost of creating and storing this data.

Example of metadata pool constantly increasing in size and number of objects:

NAME                          ID     USED      %USED     MAX AVAIL     OBJECTS
...
    default.rgw.buckets.data      17     3092G      0.86          345T     2013585
...
    default.rgw.meta              25      743M         0          172T     1975937

This is in 10.2.2-508-g9bfc0cf (9bfc0cf178dc21b0fe33e0ce3b90a18858abaf1b)

I'm not Abhishek, but AFAIK 10.2.3 has already been approved and release is imminent.
