What's New in Apache Phoenix

New features and functional updates for Phoenix are introduced in Cloudera Runtime 7.3.2, its service packs, and cumulative hotfixes.

Cloudera Runtime 7.3.2:

IPv6 support for Phoenix

Starting with the 7.3.2 release, Phoenix 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.

For more information, see Enabling IPv6 support for Phoenix.

Phoenix supports cluster-wide metadata upgrade blocks

Phoenix now provides the ability to block cluster-wide metadata auto-upgrades. To prevent an upgrade from occurring, you must add a BLOCK_UPGRADE row in the SYSTEM.MUTEX or SYSTEM:MUTEX HBase table (depending on whether namespace mapping is enabled), in the 0:MUTEX_VALUE column family, before you start Phoenix with the upgraded versions. To add the row by using the HBase shell, run the following command:

put 'SYSTEM:MUTEX','BLOCK_UPGRADE','0:MUTEX_VALUE','MUTEX_LOCKED'

For a Java code example, see the LoadSystemTableSnapshotBase.java file in the Apache Phoenix repository.

Phoenix JDK 17 upgrade

Phoenix supports JDK 17 starting with the 7.3.2 release; upgrading to JDK 17 ensures your application stays competitive and maintainable by providing improved performance, increased security, modern language features, and long-term support.

Deprecation of OMID service

The OMID service is removed from the Cloudera on cloud installation of Cloudera Runtime 7.3.2. This change is implemented because OMID appears to be unused in these environments. Consequently, the OMID service is no longer automatically deployed, effective immediately.

Users who still require OMID are not losing access to the service. You can still install OMID manually through Cloudera Manager if needed for your operations.

Apache Phoenix component upgraded to 5.2.1

The Phoenix runtime component upgrades from 5.1.3 to 5.2.1. This release delivers performance enhancements and introduces cluster-wide metadata upgrade blocks, providing you with greater control during upgrades and increasing stability in modern environments.
