> Exchange queue is not used properly

> Key: IGNITE-5100
> URL: https://issues.apache.org/jira/browse/IGNITE-5100
> Project: Ignite
> Issue Type: Bug
> Components: general
> Affects Versions: 1.6
> Reporter: Alexei Scherbakov
> Assignee: Stanilovsky Evgeny
> Priority: Critical
> Fix For: 2.1
>
>
> Currently exchange futures share same queue for pending(incomplete) and completed exchanges.
> The queue has fixed hardcoded size of 1000.
> This leads to a problem when > 1000 nodes try to enter grid.
> In such case oldest exchanges will be removed by ExchangeFutureSet size limit, leading to whole exchange hanging.
> Solution:
> 1. Use separate queues for pending and completed exchanges.
> 2. Pending exchange queue must be unbounded.
> 3. Add system property to control exchange history.
