Hi Laura, We have used pool compression in the past and found it to work well. We had it on 4/2 EC pool and found data ended up near 1:1 pool:raw. We were storing backup data in this cephfs pool, however we changed the backup product and as the data is now encrypted at rest by the application the bluestore compression is unnecessary overhead for zero gain so we are nolonger using it.
