| <p>The API to Cassandra is <a class="reference internal" href="../cql/index.html#cql"><span class="std std-ref">CQL</span></a>, the Cassandra Query Language. To use CQL, you will need to connect to the |
| cluster, which can be done:</p> |
| <ul class="simple"> |
| <li>either using cqlsh,</li> |
| <li>or through a client driver for Cassandra.</li> |
| </ul> |
| <div class="section" id="cqlsh"> |
| <h2>CQLSH<a class="headerlink" href="#cqlsh" title="Permalink to this headline">¶</a></h2> |
| <p>cqlsh is a command line shell for interacting with Cassandra through CQL. It is shipped with every Cassandra package, |
| and can be found in the bin/ directory alongside the cassandra executable. It connects to the single node specified on |
| the command line. For example:</p> |
| <div class="highlight-default notranslate"><div class="highlight"><pre><span></span>$ bin/cqlsh localhost |
| Connected to Test Cluster at localhost:9042. |
| [cqlsh 5.0.1 | Cassandra 3.8 | CQL spec 3.4.2 | Native protocol v4] |
| Use HELP for help. |
| cqlsh> SELECT cluster_name, listen_address FROM system.local; |
| |
| cluster_name | listen_address |
| --------------+---------------- |
