GitHub user adp2201 created a discussion: Q2 2026 roadmap planning
## Q2 2026 roadmap planning Hi all, Q2 is coming up, so it seems like a good time to start a fresh roadmap discussion building on the Q1 thread: - Q1 roadmap: https://github.com/apache/datafusion/issues/18494 The goals here are simple: 1. Identify what should carry forward from Q1 into Q2 2. Identify what new projects we think should be prioritized in Q2 ## Likely carry-forward themes >From the Q1 discussion, these seem like the clearest themes to continue: - **Performance** - ClickBench / Parquet leaderboard - Parquet pushdown / late materialization - planning speed - sort / join / spilling improvements - **Developer experience / coordination** - CI reliability - contributor workflow - better coordination across active efforts - **Extensibility / SQL surface** - extension types / UDTs - `VARIANT` - lambda syntax / array functionality - async UDF / UDTF work - datetime / timezone improvements ## Some concrete Q2 candidates A few open epics / proposal epics that seem especially relevant: - **Improve query planning speed**: #19795 - **ClickBench Parquet leaderboard**: #18489 - **Improve NUMA-awareness**: #20902 - **Sort-merge join execution improvements**: #20910 - **Support `VARIANT`**: #16116 - **Support Extension Types / UDTs**: #12644 - **Improve developer / CI speed**: #13813 - **Dynamic filtering**: #15512 - **Statistics improvements**: #8227 ## Questions - Which Q1 themes should clearly carry into Q2? - Which open epics feel most important right now? - What important Q2 projects are missing? - Which efforts need more implementation help, benchmarking, or design work? If you already plan to work on something in Q2, please comment with the issue / epic and the kind of help you’d welcome from others.
