[jira] [Created] (IGNITE-17394) Implement API for getting partition mapping

Igor Sapego created IGNITE-17394:
------------------------------------

             Summary: Implement API for getting partition mapping
                 Key: IGNITE-17394
                 URL: https://issues.apache.org/jira/browse/IGNITE-17394
             Project: Ignite
          Issue Type: New Feature
    Affects Versions: 3.0.0-alpha5
            Reporter: Igor Sapego
             Fix For: 3.0.0-alpha6


To implement Partition Awareness feature for clients, we need an internal or public API that will provide us with the following mapping: [partition => node] (or [node => partitions]).

We also need a lightweight mechanism that will allow us to discover that this distribution has changed. In 2.x we used a topology version for this purpose, assuming that if topology version has changed, partition distribution should be refreshed.
