+title: Apache Kudu (incubating) Weekly Update July 11, 2016
+author: Jean-Daniel Cryans
+---
+Welcome to the sixteenth edition of the Kudu Weekly Update. This weekly blog post
+covers ongoing development and news in the Apache Kudu (incubating) project.
+
+<!--more-->
+
+## Development discussions and code in progress
+
+* Todd Lipcon [changed the default](https://gerrit.cloudera.org/#/c/3517/)
+  bloom filter false positive (FP) ratio from 1% to 0.01%. The original value
+  wasn't scientifically chosen, but testing with billions of rows on a 5
+  node cluster showed a 2x insert throughput improvement at the cost of
+  some more disk space.
+
+* J-D Cryans has been fixing some recently introduced bugs in the Java client.
+  For example, see [this patch](https://gerrit.cloudera.org/#/c/3541/) and
+  [that one](https://gerrit.cloudera.org/#/c/3586/). Testability is a major
+  concern right now in the Java client since triggering those issues requires
+  a lot of time and data.
+
+* Dan Burkert has been making progress on the non-convering range partitioned
+  tables front. The Java client [now supports](https://gerrit.cloudera.org/#/c/3388/)
+  such tables and Dan is currently implementing new functionality to add and remove
+  tablets via simple APIs.
+
+* David Alves is also making a lot of progress on the replay cache, this new component
+  on the server-side which makes it possible for tablets to identify client write
+  operations and enable exactly-once semantics. The main patch is up for review
+  [here](https://gerrit.cloudera.org/#/c/3449/).
+
+* Adar Dembo is working on addressing multi-master issues, as he explained in this
+  [blog post](http://kudu.apache.org/2016/06/24/multi-master-1-0-0.html). He just put
+  up for review patches that enable tablet servers to heartbeat to all masters. Part
+  one is [available here](https://gerrit.cloudera.org/#/c/3609/).
+
+* Misty prepared a document with J-D that contains instructions on how to release a
+  new Kudu version. It is [up for review here](https://gerrit.cloudera.org/#/c/3614/)
+  if you are curious or want to learn more about this process.
+
+## Project news
+
+* The [vote](https://s.apache.org/l6Tw) to graduate Kudu from the ASF's Incubator passed!
+  The next step is for the ASF Board to vote on the resolution at their next meeting.
+
+* There's [a discussion](http://mail-archives.apache.org/mod_mbox/incubator-kudu-dev/201607.mbox/%3CCAGpTDNesxH43C-Yt5fNwpEpAxfb2P62Xpdi8AqT8jfvjeqnu0w%40mail.gmail.com%3E)
+  on the dev mailing list about having an intermediate release, called 0.10.0, before 1.0.0.
+  The current issue is that the version in the code is current "1.0.0-SNAPSHOT" which doesn't
+  leave room for another other release, but the bigger issue is that code is still churning a
+  lot which doesn't make for a stable 1.0 release.

+aware of some Kudu news we missed, let us know so we can cover it in
+a future post.
