Support for NTILE Window Function

Why it matters

The ntile window function allows users to divide ordered data into a specified number of buckets or tiles, enabling better data segmentation and ranking within partitions. This helps in analytical queries that require percentile or quantile-based grouping.

How to use it

Use the ntile function as a window function in your SELECT statements with an OVER clause to specify the partitioning and ordering. For example:

SELECT column1, ntile(4) OVER (PARTITION BY column2 ORDER BY column3) AS tile_group
FROM table_name

This will divide the rows within each partition defined by column2 into 4 buckets based on the ordering of column3.
