I think the integration between Apache Ignite and storm should be in making sure that the data that is being streamed through Storm ends up in Apache Ignite cache. For that you should simply put the data into Ignite cache. The best way to add high volumes of data into a cache is to use org.apache.ignite.IgniteDataLoader.addData(...) API.

  • Thanks Dmitriy.. How do I access the config.xml inside storm ? Storm is unable to parse the config.xml file even though all the dependency jars are available in the classpath. – user3072054 Jan 06 '15 at 23:55
  • If you are talking about GridGain config, then GridGain should parse it. Try setting GRIDGAIN_HOME environment variable to point to GridGain installation folder. – Dmitriy Jan 07 '15 at 04:04
