| <div class="entry-content"> |
| <p>Welcome to the second edition of the Kudu Weekly Update. As with last week’s |
| inaugural post, we’ll cover ongoing development and news in the Apache Kudu |
| project on a weekly basis.</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> |
| |
| <h2 id="development-discussions-and-code-in-progress">Development discussions and code in progress</h2> |
| |
| <ul> |
| <li> |
| <p>Binglin Chang’s patch for <a href="http://gerrit.cloudera.org:8080/#/c/2327/">per-tablet write quotas</a>, |
| described in last week’s post, was committed this week. This new experimental feature will be |
| available in the upcoming 0.8.0 release.</p> |
| </li> |
| <li> |
| <p>Development discussion around improving the stability of the high-availability |
| Kudu master continued on the <a href="http://gerrit.cloudera.org:8080/#/c/2527/">design doc review</a>.</p> |
| </li> |
| <li> |
| <p>Dan Burkert has been working on a <a href="http://gerrit.cloudera.org:8080/#/c/2443/">design doc</a> |
| for a “scan tokens” API as described in the <a href="https://issues.apache.org/jira/browse/KUDU-1312">KUDU-1312</a> |
| JIRA. He also posted a preliminary patch series for the |
| <a href="http://gerrit.cloudera.org:8080/#/c/2592/">Java implementation</a> of the API.</p> |
| |
| <p>This work will make it easier to integrate query and execution engines such as |
| Spark, MapReduce, and Drill with Kudu. In particular, the API aims to support features |
| such as partition pruning based on Kudu’s distribution schemas. See the design document |
| for more details.</p> |
| </li> |
| <li> |
| <p>Ara Ebrahimi has been working on a Kudu sink for Flume. This will make it easier for |
| users of Flume to build streaming ingest pipelines into Kudu tables. The |
| <a href="http://gerrit.cloudera.org:8080/#/c/2600/">code review</a> is making steady progress |
| with reviews by Mike Percy and Harsh J.</p> |
| </li> |
| <li> |
| <p>Jean-Daniel Cryans was the release manager for the past couple of releases and is |
| acting as RM again for the upcoming 0.8.0 release. This week he reminded developers |
| that <a href="http://markmail.org/thread/syfg6icqhfgxlcvi">the 0.8.0 train will soon be departing the station</a>. |
| JD is trying to follow the “train” release model: if a feature is ready when the release’s |
| time comes, it will be included. Otherwise, it will have to wait for the next release |
| to depart.</p> |
| |
| <p>The thread hasn’t generated much discussion, as it’s just a reminder of the schedule |
| that JD proposed a few months back. However, the focus this coming week will likely |
| be on fixing blockers and getting the last bits and pieces of in-flight features |
| in before a release candidate is cut.</p> |
| </li> |
| </ul> |
| |
| <h2 id="upcoming-talks-and-meetups">Upcoming talks and meetups</h2> |
| |
| <ul> |
| <li>This week, O’Reilly and Cloudera will be hosting the Strata/Hadoop World |
| in San Jose. The conference will feature two talks on Kudu:</li> |
| </ul> |
| |
| <ol> |
| <li>Thu, Mar 31, 2016. <a href="http://conferences.oreilly.com/strata/hadoop-big-data-ca/public/schedule/detail/47055">Strata Hadoop World</a>. San Jose, CA, USA.<br /> |
| <em>Fast data made easy with Apache Kafka and Apache Kudu (incubating)</em>. Presented by Ted Malaska and Jeff Holoman.</li> |
| <li>Wed, Mar 30, 2016. <a href="http://conferences.oreilly.com/strata/hadoop-big-data-ca/public/schedule/detail/46916">Strata Hadoop World</a>. San Jose, CA, USA.<br /> |
| <em>Hadoop’s storage gap: Resolving transactional-access and analytic-performance tradeoffs with Apache Kudu (incubating)</em>. Presented by Todd Lipcon.</li> |
