>                 URL: https://issues.apache.org/jira/browse/IGNITE-10920
>             Project: Ignite
>          Issue Type: Improvement
>            Reporter: Alexei Scherbakov
>            Assignee: Konstantin Bolyandra
>            Priority: Major
>
> With large topology and large amount of caches/partitions many server discovery events may quickly produce large affinity history, eating gigabytes of heap.
> Solution: implement some kind of a compression for affinity cache map.
> On example, affinity history could be stored as delta to some previous version.
