----------------------------------------------------------------
Dmitriy, affinityCall/Run over a partition is useful, I agree.
But dealing with partitions manually is also error-prone and not obvious at all.
Invoke over all cache entries is a simple common task, why not provide a simple
method of doing it?
What kind of memory issues do you expect?
Returning EntryProcessorResult for each entry on a huge cache is an obvious
problem, same as calling getAll on QueryCursor, for example. We can't protect
users from such things.

> Key: IGNITE-3222
> URL: https://issues.apache.org/jira/browse/IGNITE-3222
> Project: Ignite
> Issue Type: Task
> Components: cache
> Affects Versions: 1.1.4
> Reporter: Pavel Tupitsyn
> Fix For: 1.7
>
>
> Implement an invokeAll overload that processes all cache keys (not some
> specific set).
> Proposed signature:
> {code}
> public void invokeAll(CacheEntryProcessor<K, V, T> entryProcessor, Object...
> args);
> public <T> Map<K, EntryProcessorResult<T>> invokeAll(CacheEntryProcessor<K,
> V, T> entryProcessor, boolean returnAffectedOnly, Object... args);
> {code}
> This will apply the specified processor to all cache entries.
> First method does not return anything.
> Second method either returns all results for all entries, or only for entries
> that have been changed by the processor in any way.
