+title: Apache Kudu (incubating) Weekly Update May 3, 2016
+author: Todd Lipcon
+---
+Welcome to the seventh 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.
+
+## Development discussions and code in progress
+
+* Chris George completed his
+ [improved Spark DataSource implementation for Kudu](http://gerrit.cloudera.org:8080/#/c/2848/)
+ and the new feature will be available in the upcoming 0.9.0 release.
+ The improved DataSource supports features such as predicate pushdown
+ and Chris reports that it is able to perform subsecond queries on
+ millions of rows of data.
+
+* As mentioned last week, Binglin Chang has been working on and off
+ on a new [Get API](https://issues.apache.org/jira/browse/KUDU-1235) for
+ Kudu. The purpose of this new API is to provide an optimized path for
+ looking up a single row.
+
+ In some initial benchmarking of the feature, it became apparent that Kudu's
+ RPC mechanism was a scalability bottleneck on servers with 12 or more CPU
+ cores. With some more prototype optimizations of the RPC system, Binglin
+ has been able to push approximately 220K random reads per second on a single
+ server.
+
+ It may be a few more weeks before this work progresses from prototype stage
+ to completion, but initial results are looking quite promising.
+
+* Discussion continued on the design document for the upcoming
+ [http://gerrit.cloudera.org:8080/#/c/2642/](Replay Cache) feature. This feature
+ was previously introduced in an [earlier weekly update
+ post](http://getkudu.io/2016/04/11/weekly-update.html)
+ and development is now fully under way.
+
+## On the Kudu blog
+
+* Todd Lipcon wrote a post about [benchmarking Kudu insert performance with
+ YCSB](http://getkudu.io/2016/04/26/ycsb.html). This post was quite popular,
+ so Todd is currently working on a follow-up which will include more experiments
+ around Kudu configuration tuning.
+
+## Upcoming talks and meetups
+
+* ApacheCon Big Data will be next week in Vancouver. As always, you can check
+ the [Kudu Community page](http://getkudu.io/community.html) for an up-to-date
+ list of conferenace sessions and meetups near you.
