Ziggurat is a framework built to simplify Stream processing on Kafka. It can be used to create a full-fledged Clojure app that reads and processes messages from Kafka. Ziggurat is built with the intent to abstract out
from a clojure application such that a user only needs to pass a function that will be mapped to every message received from Kafka.
Ziggurat also sets up a HTTP server by default and you can pass in your own routes that it will serve. The above example demonstrates how you can pass in your own route.
Feature implementation of issue #56. Stop and start streams on a running process using nREPL. A nREPL server starts at port 7011(default) when an actor using ziggurat starts. Check ZIGGURAT_NREPL_SERVER_PORT in your config.
Version 3.0.0 of Ziggurat introduces the support of Middleware. Old versions of Ziggurat (< 3.0) assumed that the messages read from kafka were serialized in proto-format and thus it deserialized them and passed a clojure map to the mapper-fn. We have now pulled the deserialization function into a middleware and users have the freedom to use this function to deserialize their messages or define their custom middlewares. This enables ziggurat to process messages serialized in any format.
The handler-fn gets a serialized message from kafka and thus we need a deserialize-message function. We have provided default deserializers in Ziggurat
