> 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.
