Ravindra Pesala updated CARBONDATA-117: --------------------------------------- Fix Version/s: 0.1.1-incubating > 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 > Fix For: 0.2.0-incubating, 0.1.1-incubating > > > *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. > -- This message was sent by Atlassian JIRA (v6.3.4#6332)
