+The Cassandra sink connector pulls messages from Pulsar topics to Cassandra clusters.
+
+## Configuration
+
+The configuration of the Cassandra sink connector has the following properties.
+
+### Property
+
+| Name | Type|Required | Default | Description 
+|------|----------|----------|---------|-------------|
+| `roots` | String|true | " " (empty string) | A comma-separated list of Cassandra hosts to connect to.|
+| `keyspace` | String|true| " " (empty string)| The key space used for writing pulsar messages. <br><br>**Note: `keyspace` should be created prior to a Cassandra sink.**|
+| `keyname` | String|true| " " (empty string)| The key name of the Cassandra column family. <br><br>The column is used for storing Pulsar message keys. <br><br>If a Pulsar message doesn't have any key associated, the message value is used as the key. |
+| `columnFamily` | String|true| " " (empty string)| The Cassandra column family name.<br><br>**Note: `columnFamily` should be created prior to a Cassandra sink.**|
+| `columnName` | String|true| " " (empty string) | The column name of the Cassandra column family.<br><br> The column is used for storing Pulsar message values. |

-The Cassandra Sink connector is used to write messages to a Cassandra Cluster.
-
-The tutorial [Connecting Pulsar with Apache Cassandra](io-quickstart.md) shows an example how to use Cassandra Sink
-connector to write messages to a Cassandra table.

-## Sink Configuration Options
-
-All the Cassandra sink settings are listed as below. All the settings are required to run a Cassandra sink.
-
-| Name | Default | Required | Description |
-|------|---------|----------|-------------|
-| `roots` | `null` | `true` | Cassandra Contact Points. A list of one or many node address. It is a comma separated `String`. |
-| `keyspace` | `null` | `true` | Cassandra Keyspace name. The keyspace should be created prior to creating the sink. |
-| `columnFamily` | `null` | `true` | Cassandra ColumnFamily name. The column family should be created prior to creating the sink. |
-| `keyname` | `null` | `true` | Key column name. The key column is used for storing Pulsar message keys. If a Pulsar message doesn't have any key associated, the message value will be used as the key. |
-| `columnName` | `null` | `true` | Value column name. The value column is used for storing Pulsar message values. |
