It will be great to have this ported to 1.6 release as well.

> RocksDB contains a number of metrics at the column family level about current memory usage, open memtables,  etc that would be useful to users wishing greater insight what rocksdb is doing. This work is inspired heavily by the comments on this rocksdb issue thread (https://github.com/facebook/rocksdb/issues/3216#issuecomment-348779233)
