| <p>Welcome to the twelfth edition of the Kudu Weekly Update. This weekly blog post |
| covers ongoing development and news in the Apache Kudu (incubating) project.</p> |
| |
| <!--more--> |
| |
| <p>If you find this post useful, please let us know by emailing the |
| <a href="mailto:user@kudu.incubator.apache.org">kudu-user mailing list</a> or |
| tweeting at <a href="https://twitter.com/ApacheKudu">@ApacheKudu</a>. Similarly, if you’re |
| aware of some Kudu news we missed, let us know so we can cover it in |
| a future post.</p> |

| |
| <ul> |
| <li> |
| <p>Jean-Daniel Cryans, put up <a href="http://mail-archives.apache.org/mod_mbox/incubator-kudu-dev/201606.mbox/%3CCAGpTDNduoQM0ktuZc1eW1XeXCcXhvPGftJ%3DLRB8Er5c2dZptvw%40mail.gmail.com%3E">0.9.0 RC1</a> |
| for vote on the dev mailing list and it passed. The Incubator PMC (IPMC) will also need |
| to vote on it before it can officially be released.</p> |
| </li> |
| <li> |
| <p>Mike Percy is working on removing LocalConsensus which is currently used for |
| single node Kudu deployments. We will instead use the Raft consensus implementation |
| with a replication factor of 1. This is to simplify development since we need to maintain two |
| consensus implementations. It will also provide a way to migrate from single node to multi-node |
| deployments. See the discussion in this <a href="http://mail-archives.apache.org/mod_mbox/kudu-dev/201605.mbox/%3CCADXBggeE6RUYchv5fa=J2geHGE8Mw4SOeoi=LjXjdfmYYSqyhQ@mail.gmail.com%3E">dev thread</a>.</p> |
| </li> |
| <li> |
| <p>Zhen Zhang got a patch in for <a href="https://issues.apache.org/jira/browse/KUDU-1444">KUDU-1444</a> |
| that adds resources usage monitoring to scanners in the C++ client. In the future this could |
| be leveraged by systems like Impala to augment the query profiles.</p> |
| </li> |
| <li> |
| <p>Longer term efforts for 1.0 are making good progress. Dan Burkert <a href="https://gerrit.cloudera.org/#/c/3255/">added support</a> |
| in the C++ client for non-covering range partitioned tables, and David Alves has a few |
| patches in for the <a href="https://gerrit.cloudera.org/#/c/2642/">Replay Cache</a>.</p> |
