Phabricator updated HIVE-4381:
------------------------------
Attachment: HIVE-4381.D10551.1.patch
rusanu requested code review of "HIVE-4381 [jira] Implement vectorized
aggregation expressions".
Reviewers: JIRA
Vector aggregate operators. Vectorized implementation for sum, min, max,
average, count and variance (std, var, samp, pop).
Introduce a skeleton VectorGroupByOperator. This does not yet address actual
group by (work onyl for full table).
Vectorized aggregate expressions are generated using the CodeGen templates
ql/src/java/org/apache/hadoop/hive/ql/exec/vector/expressions/templates/
TEST PLAN
TestVectorGroupByOperator added for JUnit
