Hi all, In iot-benchmark experiment[1], we found that LZ4 outperformed SNAPPY in terms of (de)compression time and compression ratio in most scenarios. In the VLDB2022 paper[2], we also found that LZ4 performs no worse than SNAPPY on real-world datasets.
Therefore, we consider changing the default compressor of IoTDB from SNAPPY to LZ4. How do you think about it? option 1: Change LZ4 to the default compressor option 2: Keep SNAAPY as the default compressor [1] https://apache-iotdb.feishu.cn/docx/ThmHdPKw9oJv95xvLhWco2WnnLh [2] https://sxsong.github.io/doc/22vldb-encoding.pdf -- Yanze Chen School of Software, Tsinghua University
