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

             Summary: Document partition-aware data loading
                 Key: IGNITE-13746
                 URL: https://issues.apache.org/jira/browse/IGNITE-13746
             Project: Ignite
          Issue Type: Improvement
          Components: documentation
            Reporter: Pavel Tupitsyn
            Assignee: Denis A. Magda


Document the fact that CacheStore.loadCache discards non-primary entries, and how to deal
with that properly. Old documentation has this section:
https://apacheignite.readme.io/docs/data-loading#partition-aware-data-loading

And a callout:
{code}
In case of partitioned caches and 3rd party persistence such as a relational database, keys
that are not mapped to this node, either as primary or backups, will be automatically discarded.

This is not relevant for Ignite Persistent Store where every node stores only that data for
which the node is either a primary or backup.
{code}

Additionally, it would be great to mention non-primary entries being discarded in CacheStore
Javadoc (and .NET XMLDoc):

* https://github.com/apache/ignite/blob/master/modules/platforms/dotnet/Apache.Ignite.Core/Cache/Store/ICacheStore.cs
