Igniters, Long time ago we updated the logic in discovery SPI that issues heartbeats messages from one node to another. Presently, heartbeats frequency is calculated basing on IgniteConfiguration.failureDetectionTimeout meaning that TcpDiscoverySpi.heartbeatsFrequency has nothing to do with heartbeats frequency at all.
TcpDiscoverySpi.heartbeatsFrequency defines a frequency for metrics message. So, I propose to rename this method in Apache Igntie 2.0 to something more meaningful like TcpDiscoverySpi.metricsUpdateFrequency? Do you agree? Alternatives thoughts? — Denis
