Add a property in the blosc compressor map for the number of threads argument passed to the blosc dll. This PR will only affect write operations where the user creates their own compressor as this is a fairly straighforward change.

Usage: CompressorFactory.create("blosc", "cname", "zstd", "clevel", 1, "nthreads", 4);

A second PR will contain a further update that allows for setting the number of threads when a read operation is creating the compressor automatically. This is slightly more invasive and could be accomplished in more than one way.

Dear Patric,
for the time being, we have stopped further maintenance of the library.
The people at zarr-developers plan to take over further development on Java.
Please contact @joshmoore for this.
Best Regards
Sabine

Hi, @pedson.
Thanks for working on this PR.

Currently, jzarr is not under active development, and we at Zarr will be actively maintaining the library over here.

I see that your PR has been taken care of here → zarr-developers#6, thanks, @joshmoore. We'll be doing a release soon with the changes in this PR.

More details to follow. Thanks!

Best,
Sanket Verma
