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.
