-----------------------------------------
Summary: Presto Stream Readers performance Enhancement
Key: CARBONDATA-2656
URL: https://issues.apache.org/jira/browse/CARBONDATA-2656
Project: CarbonData
Issue Type: Improvement
Components: presto-integration
Affects Versions: 1.5.0
Environment: Presto 0.187
Reporter: Sourabh Verma
Assignee: Sourabh Verma
Fix For: 1.5.0
*Background*:
In the present system, we create carbonColumnVectorImpl object in
carbonVectorbatch where carbon core fill up vector data (one by one) in column
matched data type array, later which at the time presto block builder call,
read by stream readers (based on data type) and iterated to fill up in block
and returned to presto.
*Solution*:
We can eliminate the extra iteration over the carbonColumnVectorImpl object ->
vectorArray, by extending it to create a directStreamReaders which will fill up
carbon-core vector data (one by one) directly to the block(presto), and on the
call of block builder it will return the block to the Presto.
