- Kudu JDK 17 upgrade
- Kudu supports JDK 17. Upgrading to JDK 17 ensures your application stays competitive and maintainable by providing improved performance, increased security, modern language features, and long-term support.
- IPv6 support for Kudu
- Starting with the 7.3.2 release, Kudu supports IPv6 with dual-stack functionality, allowing seamless communication over both IPv4 and IPv6 networks. This capability improves network scalability, future-proofs deployments, and enhances overall platform security.
- Support for one-dimensional arrays in Kudu
- Kudu now supports one-dimensional arrays for scalar types, such as integers, strings, booleans, and binaries. This feature allows you to store multiple related values in a single column, which improves query performance and simplifies your data model by removing the need for complex joins or denormalized tables.
- Replicating Kudu tables using Apache Flink
- You can now use the Apache Flink-based replication job to continuously replicate data from a source Kudu cluster to a destination Kudu table. This feature uses Kudu diff scans to efficiently capture and move only the changed rows, supporting high-availability and disaster recovery scenarios.
