Text to vote on: -------------------------------------------------------------------------------------- *[New LTS JDK Adoption]* • When a new JDK goes LTS, we prioritize: • Moving trunk to build, run, pass CI, and support language level of that JDK, dropping others • Adding support to *run* on that JDK to all supported GA releases, passing all CI using that JDK • These 2 operations must merge atomically. This allows us to preserve the contract of allowing like-to-like JDK's for a live C* upgrade *[Build, run, language level, Pre Commit CI, EOL]* • trunk builds, runs, has CI on, and supports the language level of 1 JDK at any given time (ideally latest LTS JDK) • Supported non-trunk GA branches: • build, run, pass CI, and support the language level of *the oldest JDK they are certified for* • Are supported to *run* on all LTS JDK's between their oldest supported and newest LTS supported by trunk • In the very rare case a feature would have to be removed due to JDK change (think UDF's scripting engine), we instead keep the maximum allowable JDK for that feature supported on trunk and subsequent releases. The feature is flagged for deprecate-then-remove or re-implementation based on dev ML discussion. If removed, we drop the required older JDK across all branches when the feature is removed. Supporting new LTS JDK's is considered higher priority than supporting features that JDK's are no longer compatible with, pending debate on the dev ML. • Dropping JDK support happens naturally as old releases go EOL. *[Post Commit JDK validation CI]* • Periodically we will run all CI pipelines for all *runtime* supported JDK's for that branch (cadence TBD) • We will add basic perf testing across all GA branches + their supported runtime JDK's with reference workloads from easy-cass-stress for a simple performance-based smoke test -------------------------------------------------------------------------------------- Vote structure: • Roll call <https://cwiki.apache.org/confluence/display/CASSANDRA/Cassandra+Project+Governance> is 25. • Quorum: 13 (min required votes to qualify results) • Super-majority of participating votes in favor required to pass (9 in favor at 13 min votes, etc) Will leave the vote open for a week.
