| <p>Writing a new feature is just one way to contribute to the Cassandra |
| project. |
| In fact, making sure that supporting tasks, such as quality testing, |
| documentation, and helping users are completed is just as important. |
| Tracking the development of new features is an ongoing challenge for this project, |
| like most open source projects. |
| We suggest learning how this project gets things done before tackling a new feature. |
| Here are some suggestions for ways to contribute:</p> |
| </div> |
| <div class="ulist"> |
| <ul> |
| <li> |
| <p>Update the documentation</p> |
| </li> |
| <li> |
| <p>Answer questions on the user list</p> |
| </li> |
| <li> |
| <p>Review and test a submitted patch</p> |
| </li> |
| <li> |
| <p>Investigate and fix a reported bug</p> |
| </li> |
| <li> |
| <p>Create unit tests and d-tests</p> |
| </li> |
| </ul> |
| </div> |
| </div> |
| <div class="sect2"> |
| <h3 id="updating-documentation"><a class="anchor" href="#updating-documentation"></a>Updating documentation</h3> |
| <div class="paragraph"> |
| <p>The Cassandra documentation is maintained in the Cassandra source |
| repository along with the Cassandra code base. |
| To submit changes to the documentation, follow the standard process for |
| submitting a <a href="patches.html" class="page">patch</a>.</p> |
| </div> |
| </div> |
| <div class="sect2"> |
| <h3 id="answering-questions-on-the-user-list"><a class="anchor" href="#answering-questions-on-the-user-list"></a>Answering questions on the user list</h3> |
| <div class="paragraph"> |
| <p>Subscribe to the user list, look for some questions you can answer and write a reply. |
| Simple as that! See the <a href="http://cassandra.apache.org/community/">community</a> page |
| for details on how to subscribe to the mailing list.</p> |
| </div> |
| </div> |
| <div class="sect2"> |
| <h3 id="reviewing-and-testing-a-submitted-patch"><a class="anchor" href="#reviewing-and-testing-a-submitted-patch"></a>Reviewing and testing a submitted patch</h3> |
| <div class="paragraph"> |
| <p>Reviewing patches is not the sole domain of committers. |
| If others review a patch, it can reduce the load on the committers. |
| Less time spent reviewing patches means committers can more great features |
| or review more complex patches. |
| Follow the instructions in <a href="how_to_review.html" class="page">How to review</a> or alternatively, create a build with the patch and test it with your own workload. |
| Add a comment to the JIRA ticket to let others know you’ve reviewed and tested, |
| along with the results of your work. |
| For example:</p> |
| </div> |
| <div class="exampleblock"> |
| <div class="content"> |
| <div class="paragraph"> |
| <p>"I tested this performance enhancement on our application’s standard production |
| load test and found a 3% improvement."</p> |
| </div> |
| </div> |
| </div> |
| </div> |
| <div class="sect2"> |
| <h3 id="investigate-andor-fix-a-reported-bug"><a class="anchor" href="#investigate-andor-fix-a-reported-bug"></a>Investigate and/or fix a reported bug</h3> |
| <div class="paragraph"> |
| <p>Often, the hardest work in fixing a bug is reproducing it. |
| Even if youdon’t have the knowledge to produce a fix, figuring out a way to |
| reliably reproduce an issue can be a massive contribution. |
| Document your method of reproduction in a JIRA comment or, |
| better yet, produce an automated test that reproduces the issue and |
| attach it to the ticket. |
| If you go as far as producing a fix, follow the process for submitting a <a href="#:patches.adoc" class="page unresolved">patch</a>.</p> |
| </div> |
| <div class="paragraph"> |
| <p>To create a JIRA account, please request it on <a href="../community.html#discussions" class="page">the #cassandra or #cassandra-dev channels on ASF Slack</a>, or on <a href="../community.html#discussions" class="page">the user or dev mailing list</a>.</p> |

| <div class="sect2"> |
| <h3 id="create-unit-tests-and-dtests"><a class="anchor" href="#create-unit-tests-and-dtests"></a>Create unit tests and Dtests</h3> |
| <div class="paragraph"> |
| <p>Test coverage for Cassandra will always benefit from more automated test |
| coverage, as with most code bases. |
| Before starting work on a particular area of code, consider reviewing and |
| enhancing the existing test coverage. |
| You’ll both improve your knowledge of the code before you start on an |
| enhancement, and reduce the chance introducing issues with your change. See <a href="testing.html" class="page">testing</a> and <a href="patches.html" class="page">patches</a> for more detail.</p> |
