----------------------------------

             Summary: if filter condition has rand() 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: 2.4.0
            Reporter: roncenzhao


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.
