| <p>Pulsar bundles several <a href="/docs/en/2.8.0/io-overview#working-with-connectors">builtin connectors</a> that should be used for moving data in and out |
| of commonly used systems such as databases, messaging systems. Getting set up to use these builtin connectors is simple. You can follow |
| the <a href="/docs/en/2.8.0/getting-started-standalone#installing-builtin-connectors">instructions</a> on installing builtin connectors. After setup, all |
| the builtin connectors will be automatically discovered by Pulsar brokers (or function-workers), so no additional installation steps are |
| required.</p> |

| <p>Configuring Pulsar IO connectors is straightforward. What you need to do is to provide a yaml configuration file when your <a href="#running-connectors">run connectors</a>. |
| The yaml configuration file basically tells Pulsar where to locate the sources and sinks and how to connect those sources and sinks with Pulsar topics.</p> |
| <p>Below is an example yaml configuration file for Cassandra Sink:</p> |
| <pre><code class="hljs css language-shell">tenant: public |
| namespace: default |
| name: cassandra-test-sink |
| ... |
| <span class="hljs-meta">#</span><span class="bash"> cassandra specific config</span> |
| configs: |
| roots: "localhost:9042" |
| keyspace: "pulsar_test_keyspace" |
| columnFamily: "pulsar_test_table" |
| keyname: "key" |
| columnName: "col" |
| </code></pre> |
| <p>The example yaml basically tells Pulsar which Cassandra cluster to connect, what is the <code>keyspace</code> and <code>columnFamily</code> to be used in Cassandra for collecting data, |
| and how to map a Pulsar message into Cassandra table key and columns.</p> |
| <p>For details, consult the documentation for <a href="/docs/en/2.8.0/io-overview#working-with-connectors">individual connectors</a>.</p> |

| <p>You can submit a source to be run in an existing Pulsar cluster using a command of this form:</p> |

| <p>Here’s an example command:</p> |

| <p>Instead of submitting a source to run on an existing Pulsar cluster, you alternatively can run a source as a process on your local machine:</p> |

| </code></pre> |
| <p>If you are submitting a built-in source, you don't need to specify <code>--classname</code> and <code>--archive</code>. |
| You can simply specify the source type <code>--source-type</code>. The command to submit a built-in source is |
| in following form:</p> |
