👍 I would find this feature quite useful. I also use BGZF. |

👍 for compatibility with bgzip! |

This patch adds the ability for pigz to compress and uncompress the Blocked GNU Zip Format (BGZF) variant of gzip whose specification can be found here in the SAM specification. http://samtools.github.io/hts-specs/SAMv1.pdf
This format uses an extra field in the gzip header to encode each independent block's length, thereby allowing parallel decompression and even fast random access of the compressed archive (with indexing or other tricks)
I hope that people interested in parallel compression will be willing to sacrifice a small amount of compression-space efficiency for the ability to greatly accelerate the speed and parallelism of decompression.
