ray-doris 1.0

ray-doris 1.0

Highlights

• Initial public release of the independent, community-maintained Apache Doris read connector for
  Ray Data.
• Read exact Doris internal-catalog tables through tablet planning and streamed MySQL transport.
• Keep Flight SQL available as an explicitly selected experimental read transport.
• Provide explicit configuration, schema validation, credential redaction, and fail-closed error
  classification for the read path.

Compatibility and limitations

• Python 3.9, 3.10, and 3.12 are covered by the release compatibility matrix.
• Ray 2.49.2, 2.55.1, and 2.56.1 are the tested matrix points.
• Doris 4.0.6 is the fixed real-infrastructure target for required and distributed integration
  tests.
• MySQL is the production-candidate read transport. Flight SQL and automatic transport selection
  remain experimental.
• The read connector does not provide DDL, arbitrary SQL queries, cross-task snapshot isolation, or
  automatic replay of failed reads.

Validation

• Ruff, mypy, pre-commit, documentation, package, and Twine checks.
• Python/Ray unit and public contract tests, required Doris integration tests, and the exact-SHA
  distributed slow evidence required by the release workflow.
