high-performance C++ implementation of Apache Paimon that provides native access to the Paimon datalake format.

Always check return statuses. - -2. **Builder Pattern**: Common pattern for constructing contexts - - `WriteContextBuilder` → `WriteContext` - - `ScanContextBuilder` → `ScanContext` - - `ReadContextBuilder` → `ReadContext` - -3. **Factory Pattern**: Creation through static factory methods - - `FileStoreWrite::Create()` - - `TableScan::Create()` - - `TableRead::Create()` - -4. **Two-Phase Operations**: - - **Write**: Prepare data → Generate commit messages → Commit - - **Read**: Scan table → Create plan → Read batches - -5. **Arrow Integration**: All data interchange uses Arrow Columnar format. Batches are represented as `RecordBatch` objects wrapping Arrow arrays. - -6. **Plugin Architecture**: File formats and filesystems are pluggable through interfaces in `common/`. - -### Core Abstractions - -- **FileStoreWrite**: Writes data to Paimon tables -- **TableScan**: Scans table metadata and creates read plans -- **TableRead**: Reads data files according to plan -- **FileStoreCommit**: Commits write operations -- **Catalog**: Manages databases and tables -- **FileFormat**: Abstracts different file formats (ORC, Parquet, Avro, Lance) -- **FileSystem**: Abstracts storage backends (Local, Jindo) - -## Development Workflow - -1. **Before making changes**: Run `pre-commit run -a` to ensure code passes linting -2. **For new features**: Add unit tests alongside implementation (`*_test.cpp`) -3. **For bug fixes**: Add regression tests -4. **Before committing**: Ensure all tests pass with `ctest -j8` -5. **Architecture decisions**: Follow existing patterns for consistency - -## Important Notes - -- The codebase only supports x86_64 architecture -- Java Paimon format compatibility is maintained for commit messages, data splits, and manifests -- C++11 ABI is enabled by default (can be disabled, but some features like Lance and Lumina require it) -- Use the provided macros (`PAIMON_ASSIGN_OR_RAISE`, `PAIMON_RETURN_NOT_OK`) for error handling -- Pre-commit hooks must pass before commits can be made \ No newline at end of file diff --git a/docs/branch-management.md b/docs/branch-management.md deleted file mode 100644 index 8e873f008..000000000 --- a/docs/branch-management.md +++ /dev/null @@ -1,153 +0,0 @@ -# paimon-cpp 分支管理规范 -
