Depends on rapidsai/cudf#13635. This commit adds support for floating point order-by columns in RANGE based window functions. Prior to this commit, when the `GpuWindowExec` was presented with an order-by column of floating-point type, the entire window operation would fall back to CPU execution. This should now execute entirely on the GPU. Example query: ```sql SELECT COUNT(1) OVER (PARTITION BY grp ORDER BY float_column RANGE BETWEEN 1.023 PRECEDING AND 3.14159 FOLLOWING) FROM my_float_table; ``` Signed-off-by: MithunR <[email protected]>
