GPU-Accelerated Parquet Compaction and Index Construction for High-Cardinality Time-Series Databases

Time-series databases commonly employ LSM-Tree with Parquet columnar storage, where compaction and index construction act as major performance bottlenecks in high-cardinality IoT and cloud monitoring scenarios. Traditional CPU-only compaction suffers from low parallelism and high computation overhead, while mainstream...
