------------------------------------
Summary: Include start of record when RecordIsTooLarge
Key: KAFKA-6207
URL: https://issues.apache.org/jira/browse/KAFKA-6207
Project: Kafka
Issue Type: Bug
Components: producer
Affects Versions: 0.10.1.1
Reporter: Tadhg Pearson
Priority: Minor
When a message is too large to be send (at
org.apache.kafka.clients.producer.KafkaProducer#doSend), the
RecordTooLargeException should carry the start of the record (for example, the
first 1KB) so that the calling application can debug which message caused the
error.
For example: one common use case of Kafka is logging. The
RecordTooLargeException is thrown due to a large log message being sent by the
application. How do you know which statement in your application logged this
large message? If your exception has thousands of logging statements, it will
be very tough to find which one is the cause today.... but you include the
start of the message, this could prove a very strong hint as to the cause!
