| <h2 class="first">In-Memory MapReduce</h2> |
| <p> |
| Apache Ignite comes with in-memory implementation of Hadoop MapReduce APIs which provides |
| significant acceleration over the native Hadoop MapReduce implementation. Ignite MapReduce |
| performs much better than Hadoop due to push-based resource allocation as well as in-process |
| collocation of computations with data. |
| </p> |
| <p> |
| Additionally, since <a href="igfs.html">Ignite File System (IGFS)</a> does not need a |
| <i>Name Node</i>, when used with <i>IGFS</i>, Ignite MapReduce jobs go directly to the |
| IGFS data nodes in a single <span style="white-space: nowrap">round-trip</span>. |
