---------------------------------------
Summary: Update Spark Dialect to support ROLLUP & CUBE aggregate
functions.
Key: CALCITE-5411
URL: https://issues.apache.org/jira/browse/CALCITE-5411
Project: Calcite
Issue Type: Task
Affects Versions: 1.32.0
Reporter: Leonid Chistov
Assignee: Leonid Chistov
Support for standard
GROUP BY \{ group_expression | { ROLLUP | CUBE | GROUPING SETS } (grouping_set
[ , ...]) } [ , ... ]
syntax was added to Spark several releases ago in addition to the previously
supported non-standard syntax
GROUP BY group_expression [ , group_expression [ , ... ] ] [ WITH \{ ROLLUP |
CUBE } ]
See:
[https://spark.apache.org/docs/latest/sql-ref-syntax-qry-select-groupby.html]
We need to update `SparkSqlDialect` implementation to reflect these changes in
supported SQL syntax.
