comphead opened a new issue, #2382:
URL: https://github.com/apache/datafusion-comet/issues/2382
### What is the problem the feature request solves?
Currently `BaseAggregateExec` doesn't support some scenarios, like grouping
on maps or filtering.
```
if (aggregateExpressions.exists(_.filter.isDefined)) {
withInfo(op, "Aggregate expression with filter is not supported")
return None
}
if (groupingExpressions.exists(expr =>
expr.dataType match {
case _: MapType => true
case _ => false
})) {
withInfo(op, "Grouping on map types is not supported")
return None
}
val groupingExprs = groupingExpressions.map(exprToProto(_,
child.output))
if (groupingExprs.exists(_.isEmpty)) {
withInfo(op, "Not all grouping expressions are supported")
return None
}
```
- [ ] Support map types for aggregation
- [ ] Support agg expr with filter
