+ <p>Welcome to the fifteenth 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>Todd Lipcon diagnosed and fixed a <a href="https://gerrit.cloudera.org/3445">tricky bug</a>
+which could cause Kudu servers to crash under load. It turned out that the bug
+was in a synchronization profiling code path related to the tcmalloc allocator.
+This allocator is used in release builds, but can’t be used in instrumented builds
+such as
+<a href="http://clang.llvm.org/docs/AddressSanitizer.html">AddressSanitizer</a> or
+<a href="http://clang.llvm.org/docs/ThreadSanitizer.html">ThreadSanitizer</a>. This made it particularly difficult
+to catch. The bug fix will be released in the upcoming 0.9.1 release.</p>
+ </li>
+ <li>
+ <p>Todd also finished and committed a fix for <a href="https://issues.apache.org/jira/browse/KUDU-1469">KUDU-1469</a>,
+a bug in which Kudu’s implementation of Raft consensus could get “stuck” not making
+progress replicating operations for a tablet. See the
+<a href="https://gerrit.cloudera.org/#/c/3228/7/src/kudu/integration-tests/raft_consensus-itest.cc">new integration test case</a>
+for more details on this bug.</p>
+ </li>
+ <li>
+ <p>Mike Percy finished implementing and committed a feature which allows
+<a href="https://gerrit.cloudera.org/#/c/3135/">reserving disk space for non-Kudu processes</a>.
+This feature causes Kudu to stop allocating new data blocks on a
+disk if it is within a user-specified threshold of being full, preventing
+possible crashes and allowing for safer collocation of Kudu with other processes
+on a cluster.</p>
+ </li>
+ <li>
+ <p>Will Berkeley finished implementing <a href="https://issues.apache.org/jira/browse/KUDU-1398">KUDU-1398</a>,
+a new optimization which reduces the amount of disk space used by
+indexing structures in Kudu’s internal storage format. This should
+improve storage efficiency for workloads with large keys, and can
+also improve write performance by increasing the number of index
+entries which can fit in a given amount of cache memory.</p>
+ </li>
+ <li>
+ <p>David Alves has completed posting a patch series that implements
+exactly-once RPC semantics. The design, as mentioned in previous
+blog posts, is described in a <a href="https://gerrit.cloudera.org/#/c/2642/">design document</a>
+and the patches can be found in a 10-patch series starting with
+<a href="https://gerrit.cloudera.org/#/c/3190/">gerrit #3190</a>.</p>
+ </li>
+ <li>
+ <p>Dan Burkert is continuing working on adding support for
+<a href="https://github.com/apache/incubator-kudu/blob/master/docs/design-docs/non-covering-range-partitions.md">tables with range partitions that don’t cover the entire key
+space</a>.
+This past week, he focused on adding <a href="https://gerrit.cloudera.org/#/c/3388/">support in the the Java client</a>
+which also necessitated some serious <a href="https://gerrit.cloudera.org/#/c/3477/">refactoring</a>. These patches
+are now under review.</p>
+ </li>
+ <li>
+ <p>Congratulations to Andrew Wong, a new contributor who committed his
+first patches this week. Andrew <a href="https://gerrit.cloudera.org/#/c/3424/">improved the build docs for OSX</a>
+and also fixed a <a href="https://gerrit.cloudera.org/#/c/3486/">crash if the user forgot to specify the master address
+in some command line tools</a>.
+Thanks, Andrew!</p>

+ <p>A Kudu 0.9.1 release candidate was posted and passed a
+<a href="http://mail-archives.apache.org/mod_mbox/incubator-kudu-dev/201606.mbox/%3CCADY20s6%3D%2BnKNgvx%3DG_pKupQGiH%2B9ToS53LqExBwWM6vLp-ns9A%40mail.gmail.com%3E">release vote</a>
+by the Kudu Podling PMC (PPMC).
+The release candidate will now be voted upon by the Apache Incubator PMC. If all goes well, we
+can expect a release late this week. The release fixes a few critical bugs discovered in 0.9.0.</p>
+ </li>
+ <li>
+ <p>Chris Mattmann, one of Kudu’s mentors from the Apache Incubator,
+started a <a href="http://mail-archives.apache.org/mod_mbox/incubator-kudu-dev/201606.mbox/%3CAD4A858D-403D-4E74-A4F4-DE2F08FB761E%40jpl.nasa.gov%3E">discussion</a>
+about the project’s graduation to a top-level project (TLP).
+Initial responses seem to be positive, so the next step will
+be to work on a draft resolution and various stages of
+voting.</p>

+<p>This latest version adds basic UPSERT functionality and an improved Apache Spark Data Source
+that doesn’t rely on the MapReduce I/O formats. It also improves Tablet Server
+restart time as well as write performance under high load. Finally, Kudu now enforces
+the specification of a partitioning scheme for new tables.</p>

+
+<ul>
+ <li>
+ <p>Todd Lipcon diagnosed and fixed a <a href="https://gerrit.cloudera.org/3445">tricky bug</a>
+which could cause Kudu servers to crash under load. It turned out that the bug
+was in a synchronization profiling code path related to the tcmalloc allocator.
+This allocator is used in release builds, but can’t be used in instrumented builds
+such as
+<a href="http://clang.llvm.org/docs/AddressSanitizer.html">AddressSanitizer</a> or
+<a href="http://clang.llvm.org/docs/ThreadSanitizer.html">ThreadSanitizer</a>. This made it particularly difficult
+to catch. The bug fix will be released in the upcoming 0.9.1 release.</p>
+ </li>
+ <li>
+ <p>Todd also finished and committed a fix for <a href="https://issues.apache.org/jira/browse/KUDU-1469">KUDU-1469</a>,
+a bug in which Kudu’s implementation of Raft consensus could get “stuck” not making
+progress replicating operations for a tablet. See the
+<a href="https://gerrit.cloudera.org/#/c/3228/7/src/kudu/integration-tests/raft_consensus-itest.cc">new integration test case</a>
+for more details on this bug.</p>
+ </li>
+ <li>
+ <p>Mike Percy finished implementing and committed a feature which allows
+<a href="https://gerrit.cloudera.org/#/c/3135/">reserving disk space for non-Kudu processes</a>.
+This feature causes Kudu to stop allocating new data blocks on a
+disk if it is within a user-specified threshold of being full, preventing
+possible crashes and allowing for safer collocation of Kudu with other processes
+on a cluster.</p>
+ </li>
+ <li>
+ <p>Will Berkeley finished implementing <a href="https://issues.apache.org/jira/browse/KUDU-1398">KUDU-1398</a>,
+a new optimization which reduces the amount of disk space used by
+indexing structures in Kudu’s internal storage format. This should
+improve storage efficiency for workloads with large keys, and can
+also improve write performance by increasing the number of index
+entries which can fit in a given amount of cache memory.</p>
+ </li>
+ <li>
+ <p>David Alves has completed posting a patch series that implements
+exactly-once RPC semantics. The design, as mentioned in previous
+blog posts, is described in a <a href="https://gerrit.cloudera.org/#/c/2642/">design document</a>
+and the patches can be found in a 10-patch series starting with
+<a href="https://gerrit.cloudera.org/#/c/3190/">gerrit #3190</a>.</p>
+ </li>
+ <li>
+ <p>Dan Burkert is continuing working on adding support for
+<a href="https://github.com/apache/incubator-kudu/blob/master/docs/design-docs/non-covering-range-partitions.md">tables with range partitions that don’t cover the entire key
+space</a>.
+This past week, he focused on adding <a href="https://gerrit.cloudera.org/#/c/3388/">support in the the Java client</a>
+which also necessitated some serious <a href="https://gerrit.cloudera.org/#/c/3477/">refactoring</a>. These patches
+are now under review.</p>
+ </li>
+ <li>
+ <p>Congratulations to Andrew Wong, a new contributor who committed his
+first patches this week. Andrew <a href="https://gerrit.cloudera.org/#/c/3424/">improved the build docs for OSX</a>
+and also fixed a <a href="https://gerrit.cloudera.org/#/c/3486/">crash if the user forgot to specify the master address
+in some command line tools</a>.
+Thanks, Andrew!</p>

-RPC system was a bottleneck, and patches have started to land which improve
-the throughput:</p>
-
- <p>The largest bottleneck was in the queue which transfers RPC calls from the
-libev “reactor” threads which perform network IO to the “worker” threads
-which service the actual requests. Binglin borrowed some ideas from Facebook’s
-<a href="https://github.com/facebook/folly">folly</a> library, and implemented an
-<a href="http://gerrit.cloudera.org:8080/#/c/2938/">improved queue</a>
-which reduces context switches and lock contention while also
-improving CPU cache locality of the worker threads.</p>
-
- <p>Todd identified that the hash function used to map connections to reactor
-threads was poor, resulting in uneven load distribution across cores.
-A <a href="http://gerrit.cloudera.org:8080/#/c/2939/">simple patch to change the hashcode implementation</a>
-improved the distribution substantially.</p>
-
- <p>With just these patches, an RPC stress benchmark was improved from about 202K RPCs/second
-to 768K RPCs/second on a 24-core machine. Further improvements are in flight
-and under review this week.</p>

- <li>
- <p>Zhen Zhang is continuing to focus on adding more visibility into
-performance and resource usage by adding the ability to propagate various
-per-operation metrics from the server side back to the client. His latest patch
-under review <a href="http://gerrit.cloudera.org:8080/#/c/3013/">exposes scanner cache hit rate metrics</a>
-to the client.</p>
- </li>
- <li>
- <p>Todd Lipcon and Sarah Jelinek continue to make progress on the
-implementation of a persistent-memory backed block cache.
-This week a <a href="http://gerrit.cloudera.org:8080/#/c/2957/">substantial refactor to the block cache interface</a>
-was committed in preparation for the <a href="http://gerrit.cloudera.org:8080/#/c/2593/">NVM cache itself</a>.</p>

- <p>Congratulations to Will Berkeley, a new contributor who has been
-contributing small fixes and improvements such as
-<a href="http://gerrit.cloudera.org:8080/#/c/3022/">exposing table partitioning information in the master web UI</a>.
-Thanks, Will!</p>

- <p>David Alves has been continuing to make progress towards his implementation of
-the <a href="http://gerrit.cloudera.org:8080/#/c/2642/">Replay Cache</a>.
-This week, he refactored and cleaned up much of the client code involving
-error handling and retrying write operations, in preparation to inserting
-unique identifiers for these and other operations.</p>

- <p>Chris George has continued to work on the Spark DataSource implementation.
-In particular, work is progressing on support for <a href="http://gerrit.cloudera.org:8080/#/c/2992/">inserting and updating
-rows via Spark</a>.</p>
- </li>
- <li>
- <p>Todd Lipcon and Mike Percy both committed improvements which will help speed up
-startup. Measurements on a cluster where each node stores a few TB of data
-showed a 3x improvement in startup time.</p>
