Igniters, We have the ticket about broken randomEntry() method: https://issues.apache.org/jira/browse/IGNITE-512
This method can return null even if cache is not empty. And it is even impossible to return an entry in constant time provided that concurrent deletes and expirations could occur. Do we really need this method? As for me it is better to deprecate it and do not spend any efforts trying to make it work. Thoughts?
