About this PR / how to review
This is part 6 of 8 splitting #18140 (first-class logical
UUIDtype) into layered PRs, as requested there.The split is enabled by the v1 design:
DataType.UUIDhas stored typeBYTES, so most paths handle it automatically; each PR adds explicit UUID semantics to one subsystem. Head branch lives onxiangfu0/pinot.This PR is stacked on #18873 (branch
uuid-split/05-agg-groupby-distinct). Because GitHub PRs to apache must base onmaster, the Files-changed tab is cumulative (it includes layers 1–6) until the PRs below it merge. Review the commit titled[UUID 6/8] UUID multi-stage engine (planner + runtime)— that is this layer's change. Each parent merge shrinks this diff after a rebase.Full stack (merge bottom → top)
After #18869 lands, PRs 2/4/7 (#18870, #18872, #18875) only depend on it and can be reviewed in parallel; PRs 5/6 (#18873, #18874) also need #18871; PR 8 (#18876) needs #18874.
Full feature description, v1 design contract, scope exclusions, and benchmark numbers: #18140.
