----------------------------------
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:
