----------------------------------
Summary: support grouping set operation in dataframe api
Key: SPARK-45929
URL: https://issues.apache.org/jira/browse/SPARK-45929
Project: Spark
Issue Type: Improvement
Components: SQL
Affects Versions: 3.4.1
Reporter: JacobZheng
I am using spark dataframe api for complex calculations. When I need to use the
grouping sets function, I can only convert the expression to sql via
analyzedPlan and then splice these sql into a complex sql to execute. In some
cases, this operation generates an extremely complex sql. executing this
complex sql, antlr4 continues to consume a large amount of memory, similar to a
memory leak scenario. If you can and rollup, cube function through the
dataframe api to calculate these operations will be much simpler.
