Description
In compression.rs, there is a metadata called COMPRESSION_META_KEY used for override check.
Being marked as legacy support, it's set in multiple tests as fsst but seems only serving the needs to return early when set to none.
While in compression_config.rs, the field compression is allowed to take lz4,std or none.
