Review Comment:
   Small thing, but I think this looks a bit simpler:
   ```java
   public static Compression compressionAlgorithm() {
       if (!compressionEnabled()) {
           return Compression.NONE;
       }
       return useLZ4() ? LZ4_INSTANCE : Compression.GZIP;
   }
   ```
   
   Perhaps we could also add a comment like: `LZ4 takes precedence over GZIP if 
both are enabled.`
