We should consider switching to lz4 as a default compression algorithm. ClickHouse compresses gzip in a single thread, which is slower than alternatives.

java client uses lz4 by default python client switched to lz4 in v0.5.0 https://github.com/ClickHouse/clickhouse-connect/pull/95

LZ4 is blocked:

  • https://github.com/pierrec/node-lz4 does not support modern Node.js versions
  • https://github.com/antoniomuso/lz4-napi lacks streaming support
