Replace RocksDB with pebble?

[absolute8511]

You can use pebble by config engine type. However, currently, pebble is not stable enough to make it as default.
For example:

        "rocksdb_opts": {
            "use_shared_cache":true,
            "max_write_buffer_number":10,
            "engine_type":"pebble"
        }
