`I` am wondering if the default for BEST_SPEED should be using preset dict as that compromises speed for compression` It appears that certain scenarios might not be entirely appropriate for LZ4WithPresetDict. In principle, the read I/O may does indeed increase by double, particularly for small documents. For instance, if the size of small document is 1kb, while the dictionary is 4 KB, the read I/O will increase fourfold. I'm attempting to implement dictionary reuse by current buffer. it's lossless. It functions effectively when reading some documents from one chunk(8*10*1024). However, if the read document from different chunk, we have to rebuild the dictionary. -- This is an automated message from the Apache Git Service.
