Subject: [PATCH v2 0/5] libceph: support for replica reads
Date: Sat, 30 May 2020 17:34:34 +0200	[thread overview]
Message-ID: <20200530153439.31312-1-idryomov@gmail.com> (raw)

Hello,

This adds support for replica reads (balanced and localized reads)
to rbd and ceph.  crush_location syntax is slightly different, see
patch 3 for details.

v1 -> v2:
- change crush_location syntax
- rename read_policy to read_from_replica, add read_from_replica=no
- crush_location and read_from_replica are now overridable

Thanks,

                Ilya
