Add support for 64-bit Roaring Bitmaps in ClickHouse.
Why it matters
This feature extends ClickHouse's bitmap index capabilities by allowing the use of 64-bit Roaring Bitmaps. It addresses the limitation of 32-bit bitmap representations, enabling efficient handling of larger datasets and wider integer ranges, thereby improving performance and scalability for bitmap operations.How to use it
Users can leverage 64-bit Roaring Bitmaps transparently when working with bitmap functions and data types that support the extended range. Existing bitmap-related queries will benefit automatically from this enhancement without requiring syntax changes.
