Run a Pinot JMH benchmark twice — once on a baseline commit, once with the current changes — and report both sets of results side by side. Uses a git worktree so the user's working tree is never disturbed.

| description | Run a Pinot JMH benchmark twice — once on a baseline commit, once with the current changes — and report both sets of results side by side. Uses a git worktree so the user's working tree is never disturbed. |
Procedure: see kb/skills/bench-compare.md. Read it first, then follow it.
Pull recent GitHub Actions failures for a Pinot test class and analyze whether they share a root cause. Uses the gh CLI. Surfaces stack traces, failure patterns, and a candidate hypothesis — does not auto-fix.
Run Pinot's mandatory pre-commit checks (spotless, license, checkstyle) and compiler warning checks on only the modules affected by the current diff. Auto-fixes what it can, reports what it can't.
Launch a local Pinot quickstart cluster (batch, hybrid, streaming, upsert, etc.) with the right script, building the binary distribution first if needed.
Review Apache Pinot diffs for architectural concerns — module boundaries, SPI vs. impl separation, circular deps, misplaced logic (broker code in server, server code in controller), abstraction choice (interface vs. abstract class), plugin layering, and layering violations between pinot-spi / pinot-common / pinot-core / pinot-segment-spi / pinot-segment-local. Trigger keywords — new interface, abstract class, package move, module, SPI, broker-server boundary, plugin, shaded.
Review Apache Pinot diffs for concurrency, state management, visibility, atomic state transitions, lock changes, Helix IdealState updates, upsert metadata safety, consumer/stream ingestion races, and shared-observer correctness. Trigger keywords — synchronized, volatile, AtomicReference, ConcurrentHashMap, ReentrantLock, StampedLock, Helix, IdealState, ZkClient, version-checked write, upsert metadata, consumer coordinator, stream partition.
Review Apache Pinot diffs for configuration and backward-compatibility risks. Covers config key renames, SPI signature changes, schema/enum additions, feature-flag defaults, multi-level config override validation, rolling-upgrade safety, REST/JSON/Protobuf field evolution, and segment/DataTable format versioning. Trigger keywords — config key, config rename, SPI, feature flag, enum, schema type, DataTable version, segment version, Protobuf, Thrift, REST endpoint, @Deprecated, mixed-version, rolling upgrade, ZooKeeper schema.
