--------------------------------------------
Summary: VARIANT datatype aggregation
Key: SPARK-59150
URL: https://issues.apache.org/jira/browse/SPARK-59150
Project: Spark
Issue Type: Umbrella
Components: SQL
Affects Versions: 5.0.0
Reporter: Aleksandr Chernousov
Currently VARIANT datatype doesn't support aggregation functions (like GROUP BY
and DISTINCT). Doing so requires some convoluted workarounds.
It would be a great addition to implement that as a natively-supported
capability.
We should follow MapSort path, where we canonicalise a Variant before
aggregating it
