Positional factory function for class franzy.clients.producer.callbacks.NoOpSendCallback.

Creates a Kafka Java compatible callback for use with a producer send function.

The callback will execute when the request is complete. This callback will generally execute in the background I/O thread so it should be fast, taking minimal time to execute.

You may pass a Clojure function to create this callback, however it must be of 2 arity. The first argument will be record metadata as a map (converted from Java), and the second argument will be an exception. Your callback will receive one or the other as a value and should respond accordingly.

Example: (send-callback (fn naming-me-might-help-debug [record-metadata e] (println “Record metadata:” record-metadata) (println “Kafka said no, here’s why:” e))
