Java: How can I read Struct type data in Java

Question

I'm reading avro data from kafka and the value is of type org.apache.kafka.connect.data.Struct and the value itself looks like this Struct{f1=value3} .

How can I read just the key(f1) and value(value3)?

Answer 1

If you know the name of the field, you can do this:

Object value = struct.get("f1");

If you don't know the name of the field, you have to get all fields:

for (Field field : struct.schema().fields())
{
    String name = field.name();
    Object value = struct.get(field);
}
