[jira] [Commented] (IGNITE-4799) Remove TcpDiscoverySpi.heartbeatsFrequency parameter

["Yakov Zhdanov (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/IGNITE-4799?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15962738#comment-15962738 ] 

Yakov Zhdanov commented on IGNITE-4799:
---------------------------------------

Although I have finished the initial removal of the property and fixed tests logic and xml configs to use igniteCfg.metricsUpdateFreq, there is still a lot to do:
# we need to fix documentation to reflect the changes ([~dmagda], can you please take a look and propose changes?)
# need to decide what to do with "maxMissedHeartbeats" property and respective property for client
# should we rename and refactor TCP disco messages and logic to remove all "heartbeat mentions"?

The changes are in origin/ignite-4799

> {{TcpDiscoverySpi.heartbeatsFrequency}} is no longer used to adjust the heartbeats frequence. It affects the frequency of metrics messages sent over the cluster ring.
> The following has to be done as a part of 2.0 release:
> * Remove {{TcpDiscoverySpi.heartbeatsFrequency}} parameter.
> * Use {{IgniteConfiguraion.getMetricsUpdateFrequency}} to adjust the rate of metrics messages.
> * Make sure {{IgniteConfiguraion.getMetricsUpdateFrequency}} and metrics messages are not participated in the failure detection process. We have to clean up legacy code in {{ServerImpl}}.
> Refer to this discussion for more details:
