EugeneYushin opened a new pull request #8187: [FLINK-12197] [Formats] Avro row deser for Confluent binary format
URL: https://github.com/apache/flink/pull/8187
 
 
   ## What is the purpose of the change
   
   Currently, the following avro deserializators are available:
   
   - Core avro binary layout for both Specific/Generic and Row
   - Confluent Specific/Generic record layout
   
   The intention of this task is to fill the gap and provide Confluent avro deser for Row type.
   This will allow to harness Table API to pipelines that work with avro and Confluent schema registry.
   
   ## Brief change log
   
     - Add ConfluentRegistryAvroRowDeserializationSchema
     - Extract utilities from AvroRowDeserializationSchema
     - Use the same approach as for AvroRowDeserializationSchema, extending AbstractDeserializationSchema instead of AvroDeserializationSchema cause' the latter works with Generic/SpecificRecord abstractions from avro libs 
   
   
   ## Verifying this change
   
   This change added tests and can be verified running JUnit tests for `flink-avro` and `flink-avro-confluent-registry` modules.
