> if filter condition `And` has non-determined sub function it does not do partition prunning
> -------------------------------------------------------------------------------------------
>
> Key: SPARK-26736
> URL: https://issues.apache.org/jira/browse/SPARK-26736
> Project: Spark
> Issue Type: Improvement
> Components: SQL
> Affects Versions: 3.0.0
> Reporter: roncenzhao
> Priority: Minor
>
> Example:
> A partitioned table definition:
> _create table test(id int) partitioned by (dt string);_
> The following sql does not do partition prunning:
> _select * from test where dt='20190101' and rand() < 0.5;_
>
> I think it should do partition prunning in this case.
