-----------------------------------------
Summary: Metrics collection must be removed from discovery thread.
Key: IGNITE-5644
URL: https://issues.apache.org/jira/browse/IGNITE-5644
Project: Ignite
Issue Type: Bug
Components: cache
Reporter: Mikhail Cherkasov
Assignee: Mikhail Cherkasov
Fix For: 2.1
Cache metrics are copied in discovery worker threads. This looks a bit risky
because in case of metrics collection may stall the whole cluster. We need to
make sure that when the heartbeat message is processed, we already have a
metrics snapshot enabled
