----------------------------------------

             Summary: Provide an interface to mark user attributes used in affinity calculation
                 Key: IGNITE-5853
                 URL: https://issues.apache.org/jira/browse/IGNITE-5853
             Project: Ignite
          Issue Type: New Feature
          Components: persistence
    Affects Versions: 2.1
            Reporter: Alexey Goncharuk
             Fix For: 2.2


Since an affinity function may use user attributes to calculate affinity distribution, we need to save these attributes to the metastore. However, storing all the attributes is not very effective, so we need to have a way to determine which attributes should be stored.
