Hi K T,

I tried to explain the optimization for small ranges in non-ranged partitioning in the bug you created:
Bug#72600: similar query ranges involve different partitions

So I am basically verifying what Rick said, with the exception for smaller ranges.

If the range is larger than 2 * <number of partitions> and larger than 32 it will not be used for pruning of non range/list partitioning (also know as interval walking)..
