Apache Fluss™ C++ Bindings (Incubating)

C++ bindings for Fluss, built on top of the fluss-rust client. The API is exposed via a C++ header (include/fluss.hpp) and implemented with Rust FFI.

Requirements

• Rust (see rust-toolchain.toml at repo root)
• C++17-capable compiler
• CMake 3.18+ and/or Bazel
• Apache Arrow (for Arrow-based APIs)

Build

From the repository root or from bindings/cpp:

With CMake:

cd bindings/cpp
mkdir build && cd build
cmake ..
cmake --build .

By default, CMake now uses Release when CMAKE_BUILD_TYPE is not specified.

With Bazel:

cd bindings/cpp
bazel build //...

ci.sh defaults to optimized builds via -c opt (override with BAZEL_BUILD_FLAGS if needed). See ci.sh for the CI build sequence.

TODO

• [] How to introduce fluss-cpp in your own project, https://github.com/apache/opendal/blob/main/bindings/cpp/README.md is a good reference
• [ ] Add CMake/Bazel install and packaging instructions.
• [ ] Document API usage and minimal example in this README.
• [ ] Add more C++ examples (log scan, upsert, etc.).
