| <ul> |
| <li> |
| <p>Sameer Abhyankar posted a <a href="http://gerrit.cloudera.org:8080/#/c/2986/">patch</a> |
| for <a href="https://issues.apache.org/jira/browse/KUDU-1363">KUDU-1363</a> |
| that adds the ability to specify |
| <a href="http://www.w3schools.com/sql/sql_in.asp">IN</a>-like predicates on column values.</p> |
| </li> |
| <li> |
| <p>Chris George and Andy Grove have both been adding new features in Kudu’s |
| Spark module such as methods to <a href="http://gerrit.cloudera.org:8080/#/c/2981/">create/delete tables</a> |
| and <a href="http://gerrit.cloudera.org:8080/#/c/2992/">insert/update rows in the DataSource</a>.</p> |
| </li> |
| <li> |
| <p>Todd Lipcon <a href="https://issues.apache.org/jira/browse/KUDU-1437">fixed a bug</a> in RLE |
| encoding that was reported by Przemyslaw Maciolek. Thank you Przemyslaw for |
| reporting it and providing an easy way to reproduce it!</p> |
| </li> |
| <li> |
| <p>Adar Dembo is currently working on addressing the |
| <a href="https://github.com/cloudera/kudu/blob/master/docs/design-docs/multi-master-1.0.md">issues with multi-master</a> |
| and early last week he got <a href="http://gerrit.cloudera.org:8080/2879">a</a> |
| <a href="http://gerrit.cloudera.org:8080/2928">few</a> <a href="http://gerrit.cloudera.org:8080/2891">patches</a> |
| in that address some race conditions.</p> |
| </li> |
| <li> |
| <p>Zhen Zhang got <a href="http://gerrit.cloudera.org:8080/#/c/2858/">a first contribution</a> |
| in with a patch that adds statistics in the Java client. In 0.9.0 it will be |
| possible to query the client to get things like the number of bytes written or |
| how many write operations were sent.</p> |

| Apache Kudu (incubating) is an effort undergoing incubation at the Apache Software |
| Foundation (ASF), sponsored by the Apache Incubator PMC. Incubation is |
| required of all newly accepted projects until a further review |
| indicates that the infrastructure, communications, and decision making |
| process have stabilized in a manner consistent with other successful |
| ASF projects. While incubation status is not necessarily a reflection |
| of the completeness or stability of the code, it does indicate that the |
| project has yet to be fully endorsed by the ASF. |
