Why do we need such great number of parameters instead of having 1 on IgniteConfiguration - nodeResponseThreshold (or failureDetectionThreshold - can anyone propose better name?). > All other parameters will be calculated automatically (I think user can still set some of them for full control over situation - need to decide if this is needed.) -- This message was sent by Atlassian JIRA (v6.3.4#6332)
