Apache Drill. . Note: In Avro, GenericRecord and SpecificRecord don't have a common Record interface (just a Container interface which simply provides for a schema without any methods for accessing values), so avro4s has defined a Record trait, which is the union of the GenericRecord and SpecificRecord interfaces.Avro GenericRecord and SpecificRecord are roughly serialized at the same speed. Avro Reflect serialization is even slower than Kryo default (-45%). Tuples are the fastest, closely followed by Rows. Both leverage fast specialized serialization code based on direct access without Java reflection.Should be one of: SpecificRecord, GenericRecord. schema - writer Avro schema.

Dealing with a SR enforces to code the version of the schema into the message, generally in the first bytes. On serialization: we contact the SR to register (if not already) the Avro schema of the data we're going to write (to get a unique ID).I have also tried with an Avro schema looking like this: [ "com.zzz.yyy.Schema1", "com.zzz.yyy.Schema2" ] So that is just an UNION for the generic type object, but I can't make the avro plugin that generates the object to actually work.
