----------------------------------
Summary: Cleanup column type dependencies in vectorization
aggregate code
Key: HIVE-4604
URL: https://issues.apache.org/jira/browse/HIVE-4604
Project: Hive
Issue Type: Sub-task
Components: Query Processor
Affects Versions: vectorization-branch
Reporter: Remus Rusanu
Assignee: Remus Rusanu
Priority: Minor
The vectorized aggregates code is sprinckled with checks of the primitive types
(int, bigin, long, double, string etc), eg:
VectorHashKeyWrapperBatch.compileKeyWrapperBatch
VectorizedRowBatch.createObjectInspector
VectorizationContext.mapObjectInspectors
VectorizationContext.columnTypes
VectorizationContext.allocateColumnVector
more?
This is unmaintainable. We need to centralize and abstract all these type
checks into a single place.
