+title: Apache Kudu (incubating) Weekly Update May 23, 2016
+author: Todd Lipcon
+---
+Welcome to the tenth edition of the Kudu Weekly Update. This weekly blog post
+covers ongoing development and news in the Apache Kudu (incubating) project.
+
+<!--more-->
+
+If you find this post useful, please let us know by emailing the
+[kudu-user mailing list](mailto:user@kudu.incubator.apache.org) or
+tweeting at [@ApacheKudu](https://twitter.com/ApacheKudu). Similarly, if you're
+aware of some Kudu news we missed, let us know so we can cover it in
+a future post.
+
+## Kudu related podcast
+
+* Two committers, Mike Percy and Dan Burkert, appeared on the
+ [IBM New Builders podcast](https://developer.ibm.com/tv/apachecon-apache-projects/)
+ to talk about Apache Kudu, how they got involved, and what sort of
+ workloads it is best suited for.
+
+## Development discussions and code in progress
+
+* Jean-Daniel Cryans is again acting as the release manager for the upcoming
+ 0.9.0 release. The git branch for 0.9 has now been cut, and only bug fixes
+ or small improvements will be committed to that branch between now and the
+ first release candidate.
+
+* Since Kudu's initial release, one of the most commonly requested features
+ has been support for the `UPSERT` operation. `UPSERT`, known in some other
+ databases as `INSERT ... ON DUPLICATE KEY UPDATE`. This operation has the
+ semantics of an `INSERT` if no key already exists with the provided primary
+ key. Otherwise, it replaces the existing row with the new values.
+
+ This week, several developers collaborated to add support for this operation.
+ Todd Lipcon implemented
+ [support on the server side](http://gerrit.cloudera.org:8080/#/c/3101/),
+ C++ client, and [Python client](http://gerrit.cloudera.org:8080/#/c/3128/).
+ Jean-Daniel Cryans added support in the
+ [Java client](http://gerrit.cloudera.org:8080/#/c/3123/). Ara Ebrahimi
+ and Will Berkeley have started working on
+ [integrating upsert support into the Flume sink](http://gerrit.cloudera.org:8080/#/c/3145/).
+
+* Mike Percy started working on support for [basic disk
+ space reservations](http://gerrit.cloudera.org:8080/#/c/3135/)
+ in the tablet server. This feature will cause the tablet server to stop
+ writing to a disk before it's full, preventing crashes due to running
+ out of space.
+
+* Chris George and Andy Grove collaborated on support for [insertions and
+ updates in the Spark DataSource](http://gerrit.cloudera.org:8080/#/c/2992/),
+ and the patch was committed towards the end of the week. Brent Gardner
+ has also been helping with the Spark integration, and fixed an important
+ [connection leak bug](https://issues.apache.org/jira/browse/KUDU-1453)
+ in the initial implementation.
+
+* David Alves worked on reviving a 7-month old patch by Jingkai Yuan which
+ implements a [integer delta encoding scheme](http://gerrit.cloudera.org:8080/#/c/1210/)
+ that is meant to be efficient both in terms of CPU and disk space. This
+ encoding scheme is also designed to take advantage of modern CPU instruction sets
+ such as AVX and AVX2.
+
+
+## Upcoming talks and meetups
+
+* Ryan Bosshart will be presenting Kudu at the [Dallas/Fort Worth
+ Cloudera User Group](http://www.meetup.com/DFW-Cloudera-User-Group/events/230547045/).
