Adjust to current > topology. > So, I propose 3 new parameters which would be responsible to tune this > feature. > 1. Flag autoAdjustEnabled - true/false. Easy. Manual baseline control or auto > adjusting baseline. > 2. autoAdjustTimeout - time which we would wait after the actual topology > change. But it would be reset if new discovery event happened. (node > join/exit). > 3. autoAdjustMaxTimeout - time which we would wait from the first dicovery > event in the chain. If we achieved it than we would change BLAT right away > (no matter were another node join/exit happened or not). > We need to change API next way: > 1. org.apache.ignite.IgniteCluster > *Add* > isBaselineAutoAdjustEnabled() > setBaselineAutoAdjustEnabled(boolean enabled); > setBaselineAutoAdjustTimeout(long timeoutInMs); > setBaselineAutoAdjustMaxTimeout(long timeoutInMs); > 2. org.apache.ignite.configuration.IgniteConfiguration > *Add* > IgniteConfiguration setBaselineAutoAdjustEnabled(boolean enabled); > IgniteConfiguration setBaselineAutoAdjustTimeout(long timeoutInMs); > IgniteConfiguration setBaselineAutoAdjustMaxTimeout(long timeoutInMs); > Also, we need to ensure that all nodes would have the same parameters. > And we should be able to survive coordinator left during parameters changes. -- This message was sent by Atlassian JIRA (v7.6.3#76005)
