----------------------------------------------
Summary: Residual predicates in join operator prevent vectorization
Key: HIVE-16940
URL: https://issues.apache.org/jira/browse/HIVE-16940
Project: Hive
Issue Type: Improvement
Components: Vectorization
Affects Versions: 3.0.0
Reporter: Jesus Camacho Rodriguez
With HIVE-16885, filter predicates in ON clause for INNER joins are pushed
within the join operator (residual predicates in the operator). Previously,
residual predicates were only used for OUTER join operators.
Currently, vectorization does not support the evaluation of residual predicates
that are within an INNER join, and thus, it gets disabled if the filter
expression is pushed within the join. We should implement the vectorization of
INNER join in the presence of residual predicates.
