Hi!

I'm very interested in this project, although I (personally) have no use case right now. But I really like the idea of this concept and that existing standards (like HTTP GET range requests) are being used.

I was wondering if it is possible to create a java-only port. From what I see in the spec, I'd say: Yes, this should be possible.

The only thing which may be a bit tricky is the zstd part. As for now, there is no native java implementation (only a jni binding).
Hint: If you were going to add more compression algorithms (brotli, lz4 and lz5/lizard might be good candidates): There are at least JNI-bindings for brotli and lz4 available. lz4 is also available in plain java.

So, I'm still looking for use cases and hope that a java port would be feasible. If you do have any suggestions and/or ideas, I'd love to hear them!
