> *Problem: *
> In present scenario during querying data, the data scan can be done minimum at the block level.
> Suppose if the system can execute 10 parallel task and number of blocks to be scanned is 3, then only 3 cores could be utilised remaining 7 will be un-utilized.
> *Solution:*
> To optimize the resouce usage the blocks can be further divided into multiple blocks.
> A block consist of multiple blocklets, these blocklet could be distributed into multiple logical blocks by assigning the  startBlockletNumber and no of BlockLetsTobeScanned.
