### Purpose Linked issue: close #xxx Introduce core storage metadata components migrated from Alibaba Paimon C++: - Disk IO channel and IO manager helpers. - Writer memory manager. - Partition metadata/statistics models. - Tag metadata model and JSON serialization helpers. - View metadata model. Migration scope: - Requested and migrated files: 15 files under `src/paimon/core/disk/`, `src/paimon/core/memory/`, `src/paimon/core/partition/`, `src/paimon/core/tag/`, and `src/paimon/core/view/`. - Additional dependency files migrated in this PR: none. - Requested files skipped: none. - Known dependencies intentionally left for later migration batches include `paimon/core/snapshot.h`, `paimon/core/utils/batch_writer.h`, `paimon/core/io/compact_increment.h`, `paimon/core/io/data_increment.h`, and `paimon/core/casting/cast_executor.h`. License and contributor handling: - Converted Alibaba-owned source headers to ASF license headers. - No third-party license or NOTICE updates were required. - External contributor analysis found per-file threshold hits in `src/paimon/core/tag/*` and `src/paimon/core/view/view.h`; no `Co-authored-by` trailers were added per migration decision. ### Tests - `git diff --check` - `git diff --no-index --check <empty-dir> src/paimon/core/disk src/paimon/core/memory src/paimon/core/partition src/paimon/core/tag src/paimon/core/view` - `clang-format --dry-run --Werror src/paimon/core/disk/file_channel_manager.h src/paimon/core/disk/file_io_channel.cpp src/paimon/core/disk/file_io_channel.h src/paimon/core/disk/io_manager.h src/paimon/core/disk/io_manager_test.cpp src/paimon/core/memory/writer_memory_manager.cpp src/paimon/core/memory/writer_memory_manager.h src/paimon/core/memory/writer_memory_manager_test.cpp src/paimon/core/partition/partition_info.h src/paimon/core/partition/partition_statistics.h src/paimon/core/partition/partition_statistics_test.cpp src/paimon/core/tag/tag.cpp src/paimon/core/tag/tag.h src/paimon/core/tag/tag_test.cpp src/paimon/core/view/view.h` ### API and Format This PR adds source files under `src/paimon/core`. It does not change public headers under `include/` or storage formats by itself. ### Documentation No documentation updates. ### Generative AI tooling Migrated-by: OpenAI Codex -- This is an automated message from the Apache Git Service.
