Thanks, so librdkafka has already supported Kafka 1.0.0, right ? If Yes, I will close this issue.

It depends on what you mean, librdkafka is compatible with broker 1.0.0, but it might not support all features of Kafka 1.0.0 - Idempotent and EOS in particular are not supported.

Is there a specific feature you are looking for?

We are going to upgrade our Kafka server version to 1.0.0 to mitigate Jackthon Databind security vunerability, but we are not sure whether the latest librdkafka lib has supports Kafka 1.0.0. We are using 0.9.2 version librdkafka. Can we upgrade librdkafka lib the lastest version to keep compatible with Kafka 1.0.0. ?

Brokers are backwards compatible with old clients (>=0.8) and librdkafka is backwards compatible with older brokers (>=0.8), so both combinations are fine and yes you can (and should) upgrade to the latest release of librdkafka (0.11.3) regardless of your broker version.

Make sure to read the broker version compatibility wiki page lined above.

Thanks for all your answers, I think we can close this issue now.
