Description

~~HIVE-10238~~ showed that ?: operator can be optimized with bitwise operators when it only handles LongColumnVectors. There are more similar cases as following.

IfExprLongColumnLongScalar:

outputVector[i] = (vector1[i] == 1 ? vector2[i] : arg3Scalar);

IfExprLongScalarLongColumn:

outputVector[i] = (vector1[i] == 1 ? arg2Scalar : vector3[i]);

IfExprLongScalarLongScalar:

outputVector[i] = (vector1[i] == 1 ? arg2Scalar : arg3Scalar);
