Looks like a few changes based on the git log:
https://gist.github.com/4fa3ccc3b9be787227fed89c1bd42837

as well as a number of changes to the Java client (which gets pulled into
the Spark jar):
https://gist.github.com/e2a8ca78e51773fabb70aae34207199f


In particular, I think the partition pruning work in the Java client should
reduce the number of Spark partitions if you have predicates on your data
frames. (though I haven't personally verified it)

This is awesome!!! Great!!!

Do you know if any improvements were also made to the Spark plugin jar?

[ANNOUNCE] Apache Kudu 1.0.0 release

[Todd Lipcon]

The Apache Kudu team is happy to announce the release of Kudu 1.0.0!

Kudu is an open source storage engine for structured data which supports
low-latency random access together with efficient analytical access
patterns. It is designed within the context of the Apache Hadoop ecosystem
and supports many integrations with other data analytics projects both
inside and outside of the Apache Software Foundation.

This latest version adds several new features, including:

- Removal of multiversion concurrency control (MVCC) history is now
supported. This allows Kudu to reclaim disk space, where previously Kudu
would keep a full history of all changes made to a given table since the
beginning of time.

- Most of Kudu’s command line tools have been consolidated under a new
top-level "kudu" tool. This reduces the number of large binaries
distributed with Kudu and also includes much-improved help output.

- Administrative tools including "kudu cluster ksck" now support running
against multi-master Kudu clusters.

- The C++ client API now supports writing data in AUTO_FLUSH_BACKGROUND
mode. This can provide higher throughput for ingest workloads.

This release also includes many bug fixes, optimizations, and other
improvements, detailed in the release notes available at:
http://kudu.apache.org/releases/1.0.0/docs/release_notes.html

Download the source release here:
http://kudu.apache.org/releases/1.0.0/

Convenience binary artifacts for the Java client and various Java
integrations (eg Spark, Flume) are also now available via the ASF Maven
repository.

Enjoy the new release!

- The Apache Kudu team
