I have a data that is persisted in Avro format. Each record has a certain schema and it contains 10 fields while it is persisted.
When I read the same record(s) from other process, i also specify a schema with a subset of fields (5). Will only 5 columns be read from disk? or Will all the columns be read but 5 are later discarded? or Are all the columns read but only five are accessible since the schema used to read contain only five columns? Please suggest. Regards, Deepak
