You want to send a complex nested data structure with Kafka using Avro serialization. Which step is essential before sending the data?
AConvert the nested data to a JSON string manually
BDefine and register the Avro schema for the nested structure in the schema registry
CUse StringSerializer for the nested data
DFlatten the nested data into a single-level map

  1. Step 1: Understand Avro schema requirement

    Avro requires a schema that describes the data structure, including nested fields.

  2. Step 2: Register schema in schema registry

  3. Final Answer:

    Define and register the Avro schema for the nested structure in the schema registry -> Option B

  4. Quick Check:

    Avro nested data needs schema registration [OK]
Quick Trick: Register Avro schema before sending nested data [OK]
