Apache Kudu 1.5.0 released

The Apache Kudu team is happy to announce the release of Kudu 1.5.0!

Apache Kudu 1.5.0 is a minor release which offers several new features, improvements, optimizations, and bug fixes.

Highlights include:

• optimizations to improve write throughput and failover recovery times
• the Raft consensus implementation has been made more resilient and flexible through “tombstoned voting”, which allows Kudu to self-heal in more edge-case scenarios
• the number of threads used by Kudu servers has been further reduced, with additional reductions planned for the future
• a new configuration dashboard on the web UI which provides a high-level summary of important configuration values
• a new kudu tablet move command which moves a tablet replica from one tablet server to another
• a new kudu local_replica data_size command which summarizes the space usage of a local tablet
• all on-disk data is now checksummed by default, which provides error detection for improved confidence when running Kudu on unreliable hardware

The above list of changes is non-exhaustive. Please refer to the release notes for an expanded list of important improvements, bug fixes, and incompatible changes before upgrading.

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