In the case queue size > becomes large it's useful to have the ability to know what tasks are waiting > for execution in the thread pool. > Especially, for dealing with failover scenarios. > We should create a system views to expose information about striped executor > services queue. -- This message was sent by Atlassian Jira (v8.3.4#803005)
