    Hi everyone,
    We would like to share with you our thoughts on RocksDB in Ceph
      with main focus on efficient use of fast storage. Storage space
      provisioning for RocksDB is quite complex in Ceph as it includes
      several layers of abstraction. We highlight some problems while
      explaining how things are working under the hood. At the end, we
      propose several solutions to alleviate these problems.
