| <h4 id="trident">Trident</h4> |
| |
| <p>Trident is an alternative interface to Storm. It provides exactly-once processing, "transactional" datastore persistence, and a set of common stream analytics operations.</p> |

| |
| <h4 id="streams-api">Streams API</h4> |
| |
| <p>Stream APIs is another alternative interface to Storm. It provides a typed API for expressing streaming computations and supports functional style operations.</p> |
| |
| <p>NOTE: Streams API is an <code>experimental</code> feature, and further works might break backward compatibility. |
| We're also notifying it via annotating classes with marker interface <code>@InterfaceStability.Unstable</code>. </p> |

| <li><a href="Stream-API.html">Streams API</a></li> |
| </ul> |
| |
| <h4 id="sql">SQL</h4> |
| |
| <p>The Storm SQL integration allows users to run SQL queries over streaming data in Storm. </p> |
| |
| <p>NOTE: Storm SQL is an <code>experimental</code> feature, so the internals of Storm SQL and supported features are subject to change. |
| But small change will not affect the user experience. We will notify the user when breaking UX change is introduced.</p> |
