             Summary: Confusing construction of AvroSerializers for generic records
                 Key: FLINK-9569
                 URL: https://issues.apache.org/jira/browse/FLINK-9569
             Project: Flink
          Issue Type: Improvement
          Components: Type Serialization System
            Reporter: Tzu-Li (Gordon) Tai
            Assignee: Tzu-Li (Gordon) Tai


The {{AvroSerializer}} currently has a {{AvroSerializer(Class<T> type, Schema schema)}} public constructor when used for generic records.

This is a bit confusing, because when using the \{{AvroSerializer}}, the type to be serialized should always be a {{GenericData.Record}} type.

We should either:

- have a separate subclass of {{AvroSerializer}}, say {{GenericRecordAvroSerializer}} that is a {{AvroSerializer<GenericRecord>}}, or
- follow a similar approach to the instantiation methods in the {{AvroDeserialiationSchema}}.
