I started to work with Apache Storm recently. I use Storm with Clojure Storm DSL and Leiningen.
There is a very cool tool for storm topology management: Storm Flux.
My question is: How can I use flux when I am coding in storm with clojure?
I found a solution:
(ns your.namespace.boltname
(:use
[org.apache.storm clojure config])
(:gen-class :implements [org.apache.storm.topology.IRichBolt]))
(defbolt my-bolt
["data"]
[tuple collector]
(emit-bolt! collector [(f (.getString tuple 0))] :anchor tuple)
(ack! collector tuple))
(defn -execute [this tuple]
(.execute my-bolt tuple))
(defn -prepare [this conf context collector]
(.prepare my-bolt conf context collector))
(defn -cleanup [this]
(.cleanup my-bolt))
(defn -declareOutputFields [this output]
(.declareOutputFields my-bolt output))
(defn -getComponentConfiguration [this]
(.getComponentConfiguration my-bolt))
don't forget to add :aot :all
to your project.clj
.
And in your flux topology.yaml
something like:
...
bolts:
- id: "myBolt"
className: "your.namespace.boltname"
parallelism: 1
...
That's all :)
