Ivan Sadikov updated SPARK-46930:
---------------------------------
Description: {{enableStableIdentifiersForUnionType}} allows to enable
stable identifiers in Avro. We need to add another config to allow configuring
the custom prefix used in stable identifiers. Currently the value is
{{{}member_{}}}, e.g. member_int, member_string, but we should be able to
change to any value or even leave empty.
> Add support for a custom prefix for fields of Avro union type when
> enableStableIdentifiersForUnionType is enabled
