             Summary: Consistent toString implementations for byte arrays in generated messages
                 Key: KAFKA-14166
                 URL: https://issues.apache.org/jira/browse/KAFKA-14166
             Project: Kafka
          Issue Type: Improvement
            Reporter: Jason Gustafson


In the generated `toString()` implementations for message objects (such as protocol RPCs), we are a little inconsistent in how we display types with raw bytes. If the type is `Array[Byte]`, then we use Arrays.toString. If the type is `ByteBuffer` (i.e. when `zeroCopy` is set), then we use the corresponding `ByteBuffer.toString`, which is not often useful. We should try to be consistent. By default, it is probably not useful to print the full array contents, but we might print summary information (e.g. size, checksum).
