------------------------------------
Summary: Support SYSTEM.BUILTIN and SYSTEM.SESSION for function
resolution
Key: SPARK-54807
URL: https://issues.apache.org/jira/browse/SPARK-54807
Project: Spark
Issue Type: Sub-task
Components: Spark Core
Affects Versions: 4.2.0
Reporter: Serge Rielau
We should be able to reference builtin functions with builtin.foo or
system.builtin.foo.
Similarly temporary functions should be resolvable using session.foo or
system.session.foo().
This allows protection against shadowing, as well as add clarity in SQL
statements.
