### Purpose Linked issue: None Introduce the local file system implementation migrated from the Alibaba Paimon C++ repository. This PR adds: - local file primitives and file status wrappers - `LocalFileSystem` input/output stream support - local file system factory registration - local file unit coverage The requested migration scope was `src/paimon/fs/local` excluding `CMakeLists.txt`. No additional dependency files were required. License handling: - Replaced Alibaba-owned source headers with ASF headers. - Checked source and target `LICENSE` / `NOTICE`; no third-party declaration updates were required for these files. External contributor handling: - Re-ran blame-based contributor analysis for the final file set. - No external contributor thresholds were hit, so no `Co-authored-by` trailer or PR thank-you comment is needed. ### Tests - `python3 /home/jinli.zjw/.codex/skills/paimon-cpp-migrate/scripts/check_migration_batch.py --files src/paimon/fs/local/local_file_system_factory.h src/paimon/fs/local/local_file_test.cpp src/paimon/fs/local/local_file.h src/paimon/fs/local/local_file_system.cpp src/paimon/fs/local/local_file_system.h src/paimon/fs/local/local_file.cpp src/paimon/fs/local/local_file_system_factory.cpp src/paimon/fs/local/local_file_status.h` - `python3 /home/jinli.zjw/.codex/skills/paimon-cpp-migrate/scripts/analyze_external_contributors.py --files src/paimon/fs/local/local_file_system_factory.h src/paimon/fs/local/local_file_test.cpp src/paimon/fs/local/local_file.h src/paimon/fs/local/local_file_system.cpp src/paimon/fs/local/local_file_system.h src/paimon/fs/local/local_file.cpp src/paimon/fs/local/local_file_system_factory.cpp src/paimon/fs/local/local_file_status.h` - `clang-format -i src/paimon/fs/local/local_file_system_factory.h src/paimon/fs/local/local_file_test.cpp src/paimon/fs/local/local_file.h src/paimon/fs/local/local_file_system.cpp src/paimon/fs/local/local_file_system.h src/paimon/fs/local/local_file.cpp src/paimon/fs/local/local_file_system_factory.cpp src/paimon/fs/local/local_file_status.h` - `git diff --cached --check` - `c++ -std=c++17 -Iinclude -Isrc -fPIC -c src/paimon/fs/local/local_file_system_factory.cpp -o /tmp/paimon_local_file_system_factory_final.o` Full local build was not run because the current Apache checkout does not have a root `CMakeLists.txt`, and the existing `build/` directory does not contain generated Makefile/Ninja files. ### API and Format This adds local file system implementation classes under `src/paimon/fs/local`. It does not change public storage format or protocol. ### Documentation No documentation changes. ### Generative AI tooling Migrated-by: OpenAI Codex -- This is an automated message from the Apache Git Service.
