Re: [ceph-users] Using s3 (radosgw + ceph) like a cache

[Ben Hines]

This is how we use ceph/ radosgw.  I'd say our cluster is not that
reliable, but it's probably mostly our fault (no SSD journals, etc).

However, note that deletes are very slow in ceph. We put millions of
objects in very quickly and they are verrry slow to delete again especially
from RGW because it has to update the index too.

Hi,
I thought that xfs fragmentation or leveldb(gc list growing, locking,
...) could be a problem.
Do you have any experience with this ?

[ceph]

I do not see any issue with that

[ceph-users] Using s3 (radosgw + ceph) like a cache

[Dominik Mostowiec]

Hi,
I'm curious if using s3 like a cache -  frequent put/delete in the
long term   may cause some problems in radosgw or OSD(xfs)?
