| <p>Welcome to the fourteenth edition of the Kudu Weekly Update. This weekly blog post |
| covers ongoing development and news in the Apache Kudu (incubating) project.</p> |
| |
| <!--more--> |
| |
| <h2 id="development-discussions-and-code-in-progress">Development discussions and code in progress</h2> |
| |
| <ul> |
| <li> |
| <p>Dan Burkert posted a series of patches to <a href="https://gerrit.cloudera.org/#/c/3388/">add support in the Java client</a> |
| for non-covering range partitions. At the same time he improved how that client locates tables by |
| leveraging the tablets cache.</p> |
| </li> |
| <li> |
| <p>In the context of making multi-master reliable in 1.0, Adar Dembo posted a <a href="https://gerrit.cloudera.org/#/c/3393/">design document</a> |
| on how to handle permanent master failures. Currently the master’s code is missing some features |
| like <code>remote bootstrap</code> which makes it possible for a new replica to download a snapshot of the data |
| from the leader replica.</p> |
| </li> |
| <li> |
| <p>Tsuyoshi Ozawa refreshed <a href="https://gerrit.cloudera.org/#/c/2162/">a patch</a> posted in February that |
| makes it easier to get started contributing to Kudu by providing a Dockerfile with the right |
| environment.</p> |
| </li> |
| </ul> |
| |
| <h2 id="on-the-blog">On the blog</h2> |
| |
| <ul> |
| <li>Mike Percy <a href="http://kudu.apache.org/2016/06/17/raft-consensus-single-node.html">wrote</a> about how Kudu |
| uses Raft consensus on a single node, and some changes we’re making as Kudu is getting more mature.</li> |
| </ul> |

| Apache Kudu (incubating) is an effort undergoing incubation at the Apache Software |
| Foundation (ASF), sponsored by the Apache Incubator PMC. Incubation is |
| required of all newly accepted projects until a further review |
| indicates that the infrastructure, communications, and decision making |
| process have stabilized in a manner consistent with other successful |
| ASF projects. While incubation status is not necessarily a reflection |
| of the completeness or stability of the code, it does indicate that the |
| project has yet to be fully endorsed by the ASF. |
