Using async producers with Kafka

It's often useful to not wait for a Kafka producer to complete before moving on to the next task. In cases like this, you can use an async producer. These producers take Sarama messages on a channel and have methods to return a success/error channel that can be checked separately.

In this recipe, we'll create a go routine that will handle success and failure messages while we allow a handler to queue messages to send regardless of the result.

Getting ready

Refer to the Getting ready section of the Using Kafka with Sarama recipe.
