This is because msg_size_too_large and topic_authorization_failed error codes should be treated as an unrecoverable error. In Fluentd, we need to mark as unrecoverable with raise Fluent::Unrecoverable. But current implementation does not handle them as unrecoverable errors.

There was a problem hiding this comment.
Thanks for this fix!
I have confirmed that this feature works as intended.
Sample config:
<source>
@type tcp
tag test
<parse>
@type none
</parse>
</source>
<match test.**>
@type rdkafka2
brokers localhost:9092
topic fluentd-test
<format>
@type json
</format>
<inject>
time_key time
</inject>
<buffer []>
flush_mode immediate
chunk_limit_size 100M
</buffer>
</match>Send 10M characters:
$ echo $(base64 -w0 /dev/urandom | head -c 10000000) | nc localhost 5170
Then, msg_size_too_large error occurs, and it is handled as an unrecoverable error.
