dawidwys edited a comment on issue #8187: [FLINK-12197] [Formats] Avro row deser for Confluent binary format URL: https://github.com/apache/flink/pull/8187#issuecomment-485867174 By wrapper I meant actual wrapper, by composition not through inheritance. I am pretty sure you can have. `AvroRowDeserializationSchema` that accepts e.g. ``` interface AvroDeserializationSchemaProvider { DeserializationSchema<GenericRecord> get(Schema schema); } ``` This is to ensure the same schema is used for both the inner deserialization schema as well as for transforming from `GenericRecord` to `Row`. Then in the `AvroRowDeserializationSchema` you would have sth like: ``` class AvroRowDeserializationSchema { private final DeserializationSchema<GenericRecord> innerDeserializationSchema; ..... @Override public Row deserialize(byte[] message) throws IOException { GenericRecord row = innerDeserializationSchema.deserialize(message); return convertAvroRecordToRow(row); } .... } ```
