+If you want to use the `RocksDBStateBackend` in your IDE or configure it programmatically in your Flink job, you will have to add the following dependency to your Flink project.

 <dependency>

+  <strong>Note:</strong> Since RocksDB is part of the default Flink distribution, you do not need this dependency if you are not using any RocksDB code in your job and configure the state backend via `state.backend` and further [checkpointing]({{ site.baseurl }}/ops/config.html#checkpointing) and [RocksDB-specific]({{ site.baseurl }}/ops/config.html#rocksdb-state-backend) parameters in your `flink-conf.yaml`.
