Subject [GitHub] carbondata pull request #1075: [WIP] Datamap implementation for Blocklet.
Date Thu, 22 Jun 2017 04:55:15 GMT
GitHub user ravipesala opened a pull request:

    [WIP] Datamap implementation for Blocklet. 

    Bypassed btree implementations and used datamap to get the pruned blocklets. Only driver
side datamap is maintained and all required information will be send to  executor. 
    No datamap/btree will be maintained in executor.
    Implementation classes are 
    1. org.apache.carbondata.core.indexstore.blockletindex.BlockletTableMap
    2. org.apache.carbondata.core.indexstore.blockletindex.BlockletDataMap
    Here only used unsafe storage to store data.
