+1 (binding) Verified Apache Paimon 2.1.0 and PyPaimon 2.1.0 RC4. API compatibility is outside this vote's agreed verification scope.
Checks completed: - Both signed source archives: GPG/RSA4096 and SHA-512 pass. - Signed tag resolves to 3a5ffe7870697e2c2605e63413fb5ac5800aae7e. - Archive files match the tag; release versions, LICENSE/NOTICE, and RAT checks pass. - Paimon source core reactor builds; 73 selected Java tests pass. - PyPaimon source sdist/wheel build; 387 selected Python tests pass, 1 skipped, and 10 Lance tests are deselected because that optional dependency is absent. - Source-built wheel and exact TestPyPI 2.1.0rc4 both pass partitioned Parquet write/commit/read, null-handling, and predicate-filtering smoke tests. - TestPyPI package contents match the source-built wheel except the expected RC version in _full_version. - Nexus is closed/read-only; all 78 published modules have the required listed POM/JAR/source/signature/checksum files. - Verified representative staged API and Flink 2 common JAR signatures, checksums, legal resources, and class-file targets 52 and 55. - Release workflow provenance matches RC4 and all packaging/publishing jobs pass. Platform: macOS 26.3.1 arm64, Corretto JDK 8u432, Maven 3.9.9, Python 3.11.12, pytest 7.4.4. This was a focused verification, not a full engine/Python/JDK test matrix. The staged Spark 4 class-file target and the entire 1.9GB combined workflow repository image were not independently checked. No confirmed release blocker was found within the agreed verification scope.
