--------------------------------------
Summary: Move CRC32 to AFTER the payload
Key: KAFKA-1532
URL: https://issues.apache.org/jira/browse/KAFKA-1532
Project: Kafka
Issue Type: Improvement
Components: core, producer
Reporter: Julian Morrison
Assignee: Jun Rao
Priority: Minor
To support streaming a message of known length but unknown content, take the
CRC32 out of the message header and make it a message trailer. Then client
libraries can calculate it after streaming the message to Kafka, without
materializing the whole message in RAM.
