Qifan Chen resolved TRAFODION-1425.
-----------------------------------
Resolution: Fixed
> Parallel access to native HBase tables
> --------------------------------------
>
> Key: TRAFODION-1425
> URL: https://issues.apache.org/jira/browse/TRAFODION-1425
> Project: Apache Trafodion
> Issue Type: Bug
> Components: sql-cmp
> Reporter: Qifan Chen
> Assignee: Qifan Chen
> Labels: performance
>
> Trafodion does not create a range partitioning function for native HBase
> tables. As a result, access to these tables is serial which can hinder the
> query performance.
> The work will be done against the compiler and the following four sub-tasks
> are necessary to address the issue.
> 1. JNI code to fetch the start/end key per range, similar to Java code
> already in place :: getRegionsNodeName().
> 2. create desc_struct list
> 3. create the NAColumnArray to describe the row key, column family, column
> name, time stamp and the value
> 4. call help function createRangePartitioningFunction()
