------------------------------------
Summary: Loop optimization for SIMD in IfExprColumnColumn.txt
Key: HIVE-10238
URL: https://issues.apache.org/jira/browse/HIVE-10238
Project: Hive
Issue Type: Sub-task
Components: Vectorization
Affects Versions: 1.1.0
Reporter: Chengxiang Li
Assignee: Jitendra Nath Pandey
Priority: Minor
The ?: operator as following could not be vectorized in loop, we may transfer
it into mathematical expression.
{code:java}
for(int j = 0; j != n; j++) {
int i = sel[j];
outputVector[i] = (vector1[i] == 1 ? vector2[i] : vector3[i]);
outputIsNull[i] = (vector1[i] == 1 ?
arg2ColVector.isNull[i] : arg3ColVector.isNull[i]);
}
{code}
