Word Aligned Hybrid (WAH) Compression for BitArrays.After much searching the internet for a .net implementation for WAH compressed BitArray and not finding one, I decided to write and publish an article here so we the .net community are not left out as all the implementations are in the java language. This ties into a pretty advanced topic of bitmap indexing techniques for databases and I needed this for my upcoming RaptorDB Document data-store database engine. -After much searching the internet for a .net implementation for WAH compressed BitArray and not finding one, I decided to write and publish an article here so we the .net community are not left out as all the implementations are in the java language.　This ties into a pretty advanced topic of bitmap indexing techniques for databases and I needed this for my upcoming RaptorDB Document data-store database engine.
