[jira] [Created] (IGNITE-4222) Document the usage of ComputeJobContinuation API

Anton Vinogradov (Jira)
Denis Magda created IGNITE-4222:
-----------------------------------

             Summary: Document the usage of ComputeJobContinuation API
                 Key: IGNITE-4222
                 URL: https://issues.apache.org/jira/browse/IGNITE-4222
             Project: Ignite
          Issue Type: Task
            Reporter: Denis Magda
             Fix For: 2.0


The usage and applicability of `ComputeJobContinuation` have to be documented on Apache Ignite Readme.io which will help out to avoid discussion like that [1]. The new page has to be created for the topic and placed here [2].

The content should consist not only of technical details but also provide use cases for this API:
- don't block a thread from the public pool if a job is waiting for some result. Put the thread back into the pool and wait for the result asynchronously.
- splitting a job into several pieces that can be executed in parallel. Refer to this example [3].
