| <p>Gearpump is a real-time big data streaming engine. |
| It is inspired by recent advances in the <a href="http://akka.io/">Akka</a> framework and a desire to improve on existing streaming frameworks. |
| Gearpump is event/message based and featured as low latency handling, high performance, exactly once semantics, |
| dynamic topology update, <a href="https://storm.apache.org/">Apache Storm</a> compatibility, etc.</p> |
| <p>The name Gearpump is a reference to the engineering term "gear pump," which is a super simple |
| pump that consists of only two gears, but is very powerful at streaming water.</p> |
| <h3 id="gearpump-technical-highlights">Gearpump Technical Highlights</h3> |
| <p>Gearpump's feature set includes:</p> |
| <ul> |
| <li>Extremely high performance</li> |
| <li>Low latency</li> |
| <li>Configurable message delivery guarantee (at least once, exactly once).</li> |
| <li>Highly extensible</li> |
| <li>Dynamic DAG</li> |
| <li>Storm compatibility</li> |
| <li>Samoa compatibility</li> |
| <li>Both high level and low level API</li> |
| </ul> |
| <h3 id="gearpump-performance">Gearpump Performance</h3> |
| <p>Per initial benchmarks we are able to process 18 million messages/second (100 bytes per message) with a 8ms latency on a 4-node cluster.</p> |
