[jira] [Created] (TRAFODION-1425) Parallel access to native HBase
tables
Qifan Chen created TRAFODION-1425:
-------------------------------------
Summary: 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
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()
