Thank you for the kind words, very much appreciated!

Basically there are two cache modes (you specify it when you create the
cache tier via "ceph osd tier cache-mode {cachepool} {cache-mode}") and
when you use the writeback mode, yes the cache helps with writes as
well. See [1] (at the beginning) for details on the different cache modes.
