I have tested these codecs on the metrics data (like CPU usage). One experiment is detailed here: https://www.youtube.com/live/0fSp9SF8N8A?feature=share&t=1764

Another experiment is described in the linked blog post: https://clickhouse.com/blog/optimize-clickhouse-codecs-compression-schema https://clickhouse.com/blog/optimize-clickhouse-codecs-compr... It compares codes on the weather dataset (NOAA). The comment about "DoubleDelta" codec from the ClickHouse codebase: /** NOTE DoubleDelta is surprisingly bad name. The only excuse is that it comes from an academic paper. * Most people will think that "double delta" is just applying delta transform twice. * But in fact it is something more than applying delta transform twice. */
