Serialization InferAvroSchemaFromIon
Infer an Avro schema from an ION file
Scans up to numberOfRowsToScan rows of an ION file and infers a compatible Avro schema, writing the result as an .avsc file in Kestra's internal storage. The output URI can be passed directly to IonToAvro or IonToParquet as a schema reference.
