Runtime Encoding Execution in AnalyticDB: Efficient Query Executor for Cloud Database
Summary: Proposes Runtime Encoding Execution (REE): apply lightweight, operator-aware encodings inside the Query Executor (decoupled from storage) to accelerate higher-level operators (sort/agg/join) and intermediate results without redesigning storage. Encodings applied opportunistically when compute/memory/cache savings exceed coding overhead, leveraging order-preserving/uniqueness-friendly schemes to enable delayed-decompression-like benefits in cloud/open-store analytical DBs.
