I have a record in which one of the elements is a bitmap which can be about
a 100 bits long. Is it more efficient to store the bitmap as a binary or as
a number in Mnesia. I will be storing millions of these records.
The only operation I will be doing on these bitmaps is checking whether
certain bits are set. If using numbers I can use the "band" operator. Is
there any computation overhead when dealing with big numbers compared to
dealing with binaries in this aspect.
