Kicking the tires of reactive-kafka.
Get nice Reactive Streams interface to dealing with Kafka 0.9.0.
- with string keys
- with custom payload objects
Learn to write tests for Akka Streams.
You will need Zookeeper and Kafka 0.9.0 running, locally.
To get them on OS X, with Homebrew (note: Kafka 0.9.0 is not yet officially available in Homebrew):
$ brew install zookeeper
...
$ zkServer start
$ brew install https://raw.githubusercontent.com/iostat/homebrew2/master/Library/Formula/kafka.rb
...
$ kafka-server-start.sh /usr/local/etc/kafka/server.properties
This will launch Kafka 0.9.0 in the terminal, allowing you to see its logs.
Note: If you have an earlier, Kafka 0.8.x installed, uninstall it and also remove the /usr/local/etc/kafka folder, before
installing Kafka 0.9.0.
Reactive-kafka doesn't have a 0.9.0 release, yet (230216) so let's build and publish one locally.
$ git clone https://github.com/softwaremill/reactive-kafka.git
...
$ cd reactive-kafka
$ sbt publishLocal
Then, in the reactive-kafka-workbench folder:
$ sbt test
