# Cassandra

You can use the Cassandra connector from the CData Sync application to move data
from any supported source to the Cassandra destination. To do so, you need to add
the connector, authenticate to the connector, and complete your connection.

## Add the Cassandra Connector

To enable Sync to use data from Cassandra, you first must add the
connector, as follows:

<ol>
  <li>Open the **Connections** page of the Sync dashboard.</li>
  <li>Click **Add Connection** to open the **Select Connectors** page.</li>
  <li>Click the **Destinations** tab and locate
  the **Cassandra** row.</li>

  <li>
    Click the **Configure Connection** icon at the end of that row to open
    the **New Connection** page. This action opens the
    **Add Connection** dialog.

    **Note:** If the **Configure Connection** icon is not
    available, click the **Download Connector** icon to install
    the Cassandra connector.
  </li>

  <li>Enter a name for your connection in the **Add Connection** dialog.</li>
  <li>Click **Add** to open the **Settings** tab for your connector.</li>
</ol>

For more information about installing new connectors, see
[Connections](https://docs.sync.cdata.com/26.4/en/connections/connections.md).

## Authenticate to Cassandra

After you add the connector, you need to set the required properties.

* **Server:** Enter the host name or the IP address of the server that hosts the Cassandra database. The default host name is **localhost**.
* **Port:** Enter the port number of the server that hosts the Cassandra database. The default port value is **9042**.

CData Sync supports authenticating to Cassandra in several ways. Select your authentication method below to proceed to the relevant section that contains the authentication details.

* [**Basic**](#basic) (default)
* [**DataStax Enterprise**](#datastax-enterprise)
* [**Kerberos**](#kerberos)
* [**LDAP**](#ldap)

### Basic

To connect with your user credentials, set the following properties:

<ul><li>**Auth Scheme:** Select **Basic**.</li>
<li>**User:** Enter the username that you use to authenticate to your Cassandra account.</li>
<li>**Password:** Enter the password that you use to authenticate to your Cassandra account.</li></ul>

**Note:** In the cassandra.yaml file, you also need to set the **authenticator** property to **PasswordAuthenticator**.

### DataStax Enterprise

To connect with DataStax Enterprise credentials, specify the following properties:

* **Auth Scheme:** Select **DSE**.
* **User:** Enter the username that you use to authenticate to the Cassandra database.
* **Password:** Enter the password that you use to authenticate to the Cassandra database.

**Note:** In the cassandra.yaml file, you also need to set the **authenticator** property to **com.datastax.bdp.cassandra.auth.DseAuthenticator**.

### Kerberos

To connect with Kerberos, specify these settings:

<ul><li>**Auth Scheme:** Select **Kerberos**.</li>
<li>**User:** Enter the username that you use to authenticate to your Cassandra account.</li>
<li>**Password:** Enter the password that you use to authenticate to your Cassandra account.</li>
<li>**Kerberos KDC:** Enter the host name or IP address of your Kerberos Key Distribution Center (KDC) machine.</li>
<li>**Kerberos Realm:** Enter the Kerberos realm that you use to authenticate to Kerberos.</li>
<li>**Kerberos SPN:** Enter the service principal name (SPN) for the Kerberos domain controller.</li>
<li>**Kerberos User:** Enter the principal name for the Kerberos Domain Controller. The name should be in the form ***Host*/*User*@*Realm***.</li>
<li>(Optional) **Kerberos Keytab File:** Enter the full file path to your Kerberos keytab file.</li>
<li>(Optional) **Kerberos Ticket Cache:** Enter the full file path to an MIT Kerberos credential cache file.</li></ul>

**Note:** In the cassandra.yaml file, you also need to set the **authenticator** property to **com.datastax.bdp.cassandra.auth.DseAuthenticator**.

### LDAP

To connect with LDAP credentials, specify the following properties:

* **Auth Scheme:** Select **LDAP**.

* **LDAP Server:** Enter the host name or the IP address of your LDAP server.

* **User:** Enter the username that you use to authenticate to the Cassandra database.

* **Password:** Enter the password that you use to authenticate to the Cassandra database.

* **LDAP Password:** Enter the password of the default LDAP user.

  **Note:** You must set the password if the LDAP server does not allow anonymous bind.

* **LDAP Port:** Enter the port for your LDAP server. The default port is **389**.

* **Default LDAP User:** Enter the default LDAP user used to connect to and communicate with the server, it must be set if the LDAP server do not allow anonymous bind.

* **Search Base:** Enter the user-lookup search base for your LDAP server.

* **Search Filter:** Enter the search filter that you want to use to look up usernames in LDAP. The default setting is **(uid=)**

**Note:** In the cassandra.yaml file, you also need to set the **authenticator** property to **com.datastax.bdp.cassandra.auth.DseAuthenticator**.

## Complete Your Connection

To complete your connection:

1. Specify the following properties:
   * (Optional) **Database:** Enter the name of the Cassandra keyspace that contains your tables.
   * **Use SSL** Select whether you want to enable Secure Sockets Layer (SSL). By default, the **Enable** checkbox is not selected.
   * **Consistency Level:** Select the level that determines the number of the replicas from which you want to enforce a response before queries are considered a success. The default level is **ONE**.
2. Define advanced connection settings on the **Advanced** tab. (In most cases, though, you should not need these settings.)
3. Click **Create & Test** to create your connection.
