Incorrect remote chunking sample in documentation [BATCH-2721]

[spring-projects-issues]

Mahmoud Ben Hassine opened BATCH-2721 and commented

There are some minor errors in the remote chunking section of the documentation:

• First, the diagram shows an item reader on the worker side, but in remote chunking, the reading happens on the master side and items are sent over the wire
• The Step4 label is better if it was Step3
• The chunkJob method of the code example takes an ItemReader as parameter but uses a method call/reference in the stepBuilderFactory.reader method
• The chunkHandler bean is not needed on the master side
• According to the documentation, the middleware has to be durable, but in the code example, we declare the JMS subscription as non durable: .configureListenerContainer(c -> c.subscriptionDurable(false))
• The term "slave" is better renamed to "worker"

It would be also great to add a remote chunking sample to the spring-batch-samples module.
