| <p>Welcome to the eleventh 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, the release manager for 0.9.0, <a href="http://mail-archives.apache.org/mod_mbox/incubator-kudu-dev/201605.mbox/%3CCAGpTDNe_gV5TTsJQSjx_Q-hSGjK9TesWkyP-k9rnhd0mBtYAYg%40mail.gmail.com%3E">indicated</a> |
| that the release is almost ready and the first release candidate will be put up for vote this |
| week.</p> |
| </li> |
| <li> |
| <p>Dan Burkert pushed <a href="http://gerrit.cloudera.org:8080/3131">a change</a> that disallows default |
| partitioning when creating a new table. This is due to many reports from users experiencing bad |
| performance because their table was created with only one tablet. Kudu will now force users to |
| partition their tables.</p> |
| </li> |
| <li> |
| <p>Todd Lipcon ran YCSB stress tests on a cluster and discovered that compactions were taking hours |
| instead of seconds. He pushed <a href="http://gerrit.cloudera.org:8080/#/c/3221/">a change</a> that solves |
| the issue as part of our <a href="https://issues.apache.org/jira/browse/KUDU-749">general effort</a> to |
| improve performance for zipfian update workloads.</p> |
| </li> |
| <li> |
| <p>Todd also <a href="http://gerrit.cloudera.org:8080/#/c/3186/">changed</a> some flush-related defaults to |
| encourage parallel IO and larger flushes. This is based on his previous work that he documented |
| in this <a href="http://kudu.apache.org/2016/04/26/ycsb.html">blog post</a>.</p> |
| </li> |
| <li> |
| <p>Will Berkeley made a few improvements last week, but <a href="http://gerrit.cloudera.org:8080/3199">one</a> |
| we’d like to call out is that he removed the Java’s kudu-mapreduce module dependency on Hadoop’s |
| hadoop-common test jar. This solved build issues while also removing a nasty dependency.</p> |
