> BlockLet distribution for optimum resource usage

> Key: CARBONDATA-117
> URL: https://issues.apache.org/jira/browse/CARBONDATA-117
> Project: CarbonData
> Issue Type: Improvement
> Components: data-query
> Reporter: Mohammad Shahid Khan
> Assignee: Mohammad Shahid Khan
>
> *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.
