> CacheGroupMetrics spams to heap with java.lang.Integer
> ------------------------------------------------------
>
> Key: IGNITE-15781
> URL: https://issues.apache.org/jira/browse/IGNITE-15781
> Project: Ignite
> Issue Type: Bug
> Affects Versions: 2.11
> Reporter: Maksim Timonin
> Assignee: Maksim Timonin
> Priority: Major
> Time Spent: 0.5h
> Remaining Estimate: 0h
>
> Check GridDhtPartitionMap.get() and similar methods that expect Integer, but
> CacheMetrics uses prmitive types. Autoboxing pollutes heap much if metrics
> asks frequently.
>
> Metrics to check: getMinimumNumberOfPartitionCopies()
> this metrics iterates over all nodes and partitions and invokes get(int) on
> every iteration.
