> IndexScan node creates partitions array from BitSet, to pass it to other
> methods, where this array converted to BItSet again. It also iterates over
> partitions array to fill reserved partitions list, but this list is never
> used in IndexScan (used only in TableScan).
> Also, rowType are created each time for IndexScan, can be cached.
