​
network_compression_method

The codec for compressing the client/server and server/server communication over the native protocol. The setting does not apply to the streaming-exchange channel of distributed queries, which always uses the server default codec: every compressed frame is self-describing, so the receiver detects the codec automatically. Possible values:
  • NONE — no compression.
  • LZ4 — use the LZ4 codec.
  • LZ4HC — use the LZ4HC codec.
  • ZSTD — use the ZSTD codec.

network_zstd_compression_level
