    Description

      Simple8b blocks containing the skip bit pattern in all its slots can easily be determined by masking out the selector bits and checking if all remaining bits are set to 1.

      When this case is detected the BSONColumn decompressor can avoid unpacking every individual slot which should be a performance improvement.
