Subject: [EXTERNAL] Propose an Avro format optional schema
Hi,
I would like to propose that we have an optional schema property on the Avro
format. This would be a String of the Avro schema and should be supplied as the
correct schema to be supplied in the format. This is required because the
schema that is inferred from the table definition is not always accurate; for
example with nested objects with child objects that have different nullability
to the parent.
Confluent Avro schema format has this option already.
This will be used as the writeSchema [1] for Avro format.
I am happy to implement this,
Kind regards, David.
