--------------------------------------------
> Push down date literals to Kudu scanner
> ---------------------------------------
>
> Key: IMPALA-11496
> URL: https://issues.apache.org/jira/browse/IMPALA-11496
> Project: IMPALA
> Issue Type: Improvement
> Components: Backend, Frontend
> Reporter: Csaba Ringhofer
> Assignee: Peter Rozsa
> Priority: Major
> Labels: ramp-up
>
> To reproduce:
> explain select * from functional_kudu.date_tbl where date_col = DATE
> "1970-01-01";
> 00:SCAN KUDU [functional_kudu.date_tbl]
> predicates: date_col = DATE '1970-01-01'
> We should see "kudu predicates" instead of "predicates" if it was pushed down.
> date is missing from the following switch case, so FE doesn't create kudu
> predicates for them:

> Not sure whether backend changes are also needed
