Parallel Compression Revamp: Dramatically Reduced CPU Overhead

The upcoming RocksDB 10.7 release includes a major revamp of parallel compression that dramatically reduces the feature’s CPU overhead by up to 65% while maintaining or improving throughput for compression-heavy workloads. We expect this to broaden the set of workloads that could benefit from parallel compression, especially for bulk SST generation and remote compaction use cases that are less sen
