It doesn't block under normal circumstances, it returns a ListenableFuture which can be used to either block (get()) or get the reply asynchronously with a listenable.

It will, however, block waiting for topic metadata when the first message is sent so it's not reactive.

There is the reactor-kafka project, but Spring Kafka does not currently use it.

There is a pull request that we plan to look at for the next (2.3) release.
