> TAJO-1950 is a ticket to improve the planning for the range shuffling. The proposed solution for TAJO-1950 is to create even and fine-grained partitions using the histogram. 
> Creating partitions require frequent tuple range calculations. Implementing add and subtract methods will be helpful to facilitate these calculations.
