------------------------------------
Summary: Predicate pushdown for complex types to scan node instead
of unnest node
Key: IMPALA-9595
URL: https://issues.apache.org/jira/browse/IMPALA-9595
Project: IMPALA
Issue Type: New Feature
Components: Backend, Frontend
Reporter: Gabor Kaszab
Instead of evaluating predicates inside an unnest it would be better to push
the predicates directly into the scanner that fills the “list of tuples” slot
consumed by the unnest. For example, the predicate evaluation could be
integrated into the scanner’s DFA for projecting complex input data to the
minimal output tuple.
