This library is no longer actively developed and has been superseded by librdkafka via rdkafka-ruby bindings. While this library may still receive security patches and bug fixes, it is no longer recommended for production usage. There needs to be a concerted effort to keep up with Kafka features. There is no point in trying to keep up with Kafka development when other languages use a well-established C binding and get more official support.
