> URL: https://issues.apache.org/jira/browse/IGNITE-2264
> Project: Ignite
> Issue Type: Sub-task
> Components: cache
> Affects Versions: ignite-1.4
> Reporter: Vladimir Ozerov
> Assignee: Vladimir Ozerov
> Priority: Critical
> Fix For: 1.6
>
>
> This class has two methods: reads() and writes(). Together they return the
> whole set of entries.
> The problem is that each call creates collection wrapper over entries + 1
> additional iterator per each traverse over collection. This seen as a garbage
> "hotspot" in flight recorder.
> Actually there is no need for these methods. Instead, we can pass entries
> collection directly and filter entries manually.
