A little extra context here. Currently the metadata pool looks like it is
on track to exceed the number of objects in the data pool, over time. In a
brand new cluster, we¹re already up to almost 2 million in each pool.
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
We¹re concerned this will be unmanageable over time.
