资 源 简 介
Pcompress is a high-performance utility to do compression/decompression and deduplication in parallel by splitting input data into chunks and providing strong integrity checking. Chunk splitting can happen at fixed points or variable content-defined boundaries based on a rolling hash. It has a modular structure and includes support for multiple algorithms like LZMA, Bzip2, PPMD, LZ4, LZFX etc., with KECCAK, BLAKE2, SHA-256/512 chunk checksums. SSE optimizations for the bundled LZMA are included. Performance scales with the number of cores. Depending on the size of the data and the number of chunks it can scale to hundreds of cores.
It also implements chunk-level Content-Aware Deduplication and Delta Compression features with variable block splitting based on a polynomial rolling hash. It has low metadata overhead and overlaps I/O and compression to achieve maximum parallelism. It support
