             Summary: Improve predicate pushdown to Iceberg
                 Key: IMPALA-11243
                 URL: https://issues.apache.org/jira/browse/IMPALA-11243
             Project: IMPALA
          Issue Type: Improvement
          Components: Frontend
            Reporter: Zoltán Borók-Nagy


Iceberg provides a rich API to push down predicates, e.g. we could push down complex predicates with OR, NOT, etc.

Also, currently we only push down predicates in the form:

{noformat}
COL <bin-operator> LITERAL_EXPR
E.g.:
col_ts <= '2021-01-01 12:01:00'
{noformat}

Instead of only allowing literal expressions, we could evaluate any constant expression and push down the result to Iceberg.
