            <p class="lead">
                Apache Ratis is a highly customizable Raft protocol implementation in Java.</p>

                <h4>Pluggable transport</h4>
                <p>
                    Ratis provides a pluggable transport layer. By default gRPC, Netty+Protobuf and Apache Hadoop RPC based transports are provided.

                <h4>Pluggable state machine</h4>
                <p>
                    Ratis supports a log and state machine. State machine typically contains the data that you want to make highly available. Ratis makes it easy to use your own state machine.

              <h4>Pluggable raft log</h4>
              <p>RAFT log is also pluggable, users can provide their own log implementation. The default
                  implementation
                  stores log in local files.</p>
              <p>
                  Application can define the policies of how to write data and where it should be written easily.

              <p>Ratis provides a pluggable observation layer. By default (ratis-metrics-default), it uses the shaded Dropwizard 4 provided by ratis-thirdparty.
                Another implementation can be found in ratis-metrics-dropwizard3. Users can provide their own metrics implementations.
