Mark, Please find the Bluestore + ZS integrated code synced with today's master in the following location. https://github.com/somnathr/ceph/tree/wip-bluestore-zs As discussed in the standup , this is with single kv_sync_thread. I am still cleaning up multi kv_sync_thread version and will send out a pull request for Sage to review hopefully by tomorrow. Here is the steps you need to follow to use this. 1. ./do_cmake.sh -DWITH_ZS=1 2. make and make install 3. In the ceph.conf , use the following option. enable experimental unrecoverable data corrupting features = bluestore zs rocksdb bluestore_sync_submit_transaction = false bluestore_kvbackend=zs With smaller volumes you will be seeing rocks outperforming ZS , but, for bigger volumes ZS is catching up fast. The code (shim layer and thus BlueStore) is no way optimally using ZS yet and we are in process of optimizing it further (with multi kv_sync, more batching etc. etc.). Will keep community posted on this.
