> Support a wider range of expressions in Iceberg predicate pushdowns
> -------------------------------------------------------------------
>
> Key: IMPALA-14517
> URL: https://issues.apache.org/jira/browse/IMPALA-14517
> Project: IMPALA
> Issue Type: Improvement
> Reporter: Zoltán Borók-Nagy
> Assignee: Nándor Kollár
> Priority: Major
> Labels: impala-iceberg
>
> Currently Impala expects the exact type for Iceberg predicate pushdown.
> E.g. we have the following table:
> {noformat}
> CREATE TABLE ice_t (i int, d date)
> PARTITIONED BY SPEC (month(d))
> STORED BY ICEBERG;{noformat}
> The following pushes down the predicate:
> {noformat}
> SELECT * FROM ice_t
> WHERE d = DATE '2012-10-10';{noformat}
> The following does not:
> {noformat}
> SELECT * FROM ice_t
> WHERE d = '2012-10-10';{noformat}
> I.e. even implicit casts are not supported right now.
> We should support more expressions in our predicate pushdown logic.
