StarRocks Integrates Paimon C++ for 1.4–3.4x Faster Lake Queries via Native Execution

StarRocks adopts Apache Paimon's C++ implementation (paimon-cpp) to replace JNI calls for primary-key merges and delete-vector handling, cutting cross-language overhead and reusing StarRocks' cache, memory management, and Query Profile; benchmarks show 1.4–3.4× speedups on primary-key counts and wide-table aggregations.
