[jira] [Created] (SPARK-33015) Compute the current date only once

Maxim Gekk created SPARK-33015:
----------------------------------

             Summary: Compute the current date only once
                 Key: SPARK-33015
                 URL: https://issues.apache.org/jira/browse/SPARK-33015
             Project: Spark
          Issue Type: Bug
          Components: SQL
    Affects Versions: 3.0.2, 3.1.0
            Reporter: Maxim Gekk


According to the doc for current_date(), it must compute the current date at the start of query evaluation: http://spark.apache.org/docs/latest/api/sql/#current_date but it can compute it multiple times: https://github.com/apache/spark/blob/0df8dd60733066076967f0525210bbdb5e12415a/sql/catalyst/src/main/scala/org/apache/spark/sql/catalyst/optimizer/finishAnalysis.scala#L85
