convertAggregateExpressions(agg: Aggregation, schema: StructType): Seq[StructField]
Converts a spark aggregation into a sequence of fields.
Converts a spark aggregation into a sequence of fields. If empty the aggregation is not supported or something else went wrong.
- agg
the aggregation to convert.
- returns
a non-empty sequence if supported and present.
