----------------------------------
Summary: Java producer default max message size does not align
with broker default
Key: KAFKA-4203
URL: https://issues.apache.org/jira/browse/KAFKA-4203
Project: Kafka
Issue Type: Bug
Affects Versions: 0.8.1
Reporter: Grant Henke
Assignee: Grant Henke
Priority: Critical
The Java producer sets max.request.size = 1048576 (the base 2 version of 1 MB
(MiB))
The broker sets max.message.bytes = 1000012 (the base 10 value of 1 MB + 12
bytes for overhead)
This means that by default the producer can try to produce messages larger than
the broker will accept resulting in RecordTooLargeExceptions.
There were not similar issues in the old producer because it sets
max.message.size = 1000000 (the base 10 value of 1 MB)
I propose we increase the broker default for max.message.bytes to 1048588 (the
base 2 value of 1 MB (MiB) + 12 bytes for overhead) so that any message
produced with default configs from either producer does not result in a
RecordTooLargeException.
