-----------------------------------------
Summary: 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
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.
