Starburst Enterprise Support Updates: Java 21

Starburst Enterprise Platform (SEP) is set to transition to Java 21 in 2024, with the Trino SQL query engine running exclusively on Java 21 as of release 436. While SEP will support both Java 17 and Java 21 through the February 2024 Long Term Support (LTS) release, Java 21 will become mandatory by the May 2024 LTS release. This transition aims to harness the performance improvements and optimizations offered by Java 21, aligning with Trino’s strategy of adopting new Java LTS versions. To facilitate a smooth transition, SEP will support dual Java versions for various deployment mechanisms, encouraging users to test Java 21 in advance. The company has conducted extensive testing to assure robust support, and recommends the Eclipse Temurin OpenJDK distribution from Adoptium for users.
