> There are many uses cases for setting bits flags and being able filter on
> those seems like a good idea.
> The BitComparator would take a byte[] and a bitwise operator for its
> constructor. It would perform the bitwise operation on the column value bytes
> with the specified byte[]. Then return whether the result was non-zero.
> Only the CompareOp.EQUAL and CompareOp.NOT_EQUAL would make sense with this
> comparator.
> The binary bitwise operators that apply are AND, OR, and XOR.
