+## Installing Apache Cassandra
+There are multiple ways to bring up a Cassandra instance on local machine:
+
+1. Follow the instructions from [Cassandra Getting Started
page](http://cassandra.apache.org/doc/latest/getting_started/index.html).
+2. Launch a container running Cassandra from [Official Docker

Flink's Cassandra sink are created by using the static
CassandraSink.addSink(DataStream<IN> input) method.
-This method returns a CassandraSinkBuilder, which offers methods to
further configure the sink.

The following configuration methods can be used:
