Zstd vs LZ4 #76

Have you considered the possibility of offering Zstd to users? So they can decide between the two compression algorithms. Zstd with parameters for faster compression may offer better compression, with a little extra compression time.

We have considered allowing users the option of specifying a different compression algorithm. I'm not familiar with Zstd, but it appears to be integrated into the Linux kernel, so it should be possible without too much difficulty.

We don't currently have a solid schedule for when this feature might become available, though.
