Description

The default compression level of 5 for Zstandard is too high for the majority
of use cases since it requires too many CPU cycles. The upstream Zstandard
project uses 3 as the default, but I feel like a default of 1 will work for
many more clusters. I have another patch in the works which will make this a
configurable option (#43377).
