VUS Core Design Todo

Todo

1. Camel to consume messages off ActiveMQ produced with ActiveMQ example (producer)

• configure multiple camel consumers in single vm to consume messages via ActiveMQ
• Set up Akka
• Point Camel to Akka with Akka-Camel
• Pass message from Client - [Camel endpoint] -> ActiveMQ -> [Camel enpoint] -> Akka
• Explore different setting with ActiveMQ producer/consumer example. e.g. try durable, reply to, etc - determine different categories by looking at the source code, also try ByteMessage instead of TextMessage
  • I think the dicision on message body type needs to be a part of Integration stream (then the core assume what format?)

Backlog

1. Confirm thread model for both
   • Camel (http://camel.apache.org/threading-model.html)
   • Akka

• Set up Neo4j
• Set up basic structure, try both server tool and program
• Invoke query via using
  • Spring Data Neo4j
  • Cypher

Done

1. Finish Spring Data Neo4j chapter
   • Need to consider if to use GraphDB
   • Need to consider between Spring Data or direct
   • Related to above, think about the use cases in terms of "object" model vs more "graphy" approach, i.e. is object-to-graph mapping a requirements?
   • Consider Spring Data use without OG mapping. Is it possible to just use "Repository"? (I don't think so but not 100% sure)
   • Think about transactions (JTA) in the context of non-application server
   • Think about the use of "Live View" use, AspectJ adds more complexity?
   • Weigh out the choice between "embedded" mode vs. "server" mode
     • how to scale out if "embedded"? - I don't think it's possible so "server" mode is needed in that case?
2. Try ActiveMQ set up
   • Installed and ran example code, producer and consumer
     • according to this
   • and checked out web console
     • it also has nice descriptions on how to run the console for embedded activeMQ, which I think it'll be useful for integration tests
   • also check out JMX, JConsole description
