I highly recommend against storing data structures like this in C*. That
really isn't it's sweet spot.  For instance, if you were to use the blob
type which will give you the smallest size, you are still looking at a cell
size of (90,000,000/8/1024) = 10,986 or over 10MB in size, which is
prohibitively large.

Additionally, there is no way to modify the bitmap in place, you would have
to read the entire structure out and write it back in.

You could store one bit per cell, but that would essentially defeat the
purpose of the bitmap's compact size.
