Hi, The heap metrics that you see in topology message shows the max heap value that your cluster can use:
Math.max(m.getHeapMemoryInitialized(), m.getHeapMemoryMaximum() Initial heap size (-Xms ) is different from the maximum (-Xmx). Your JVM will be started with Xms amount of memory and will be able to use a maximum of Xmx amount of memory. Looks like Ignite has the recommendation to set Xms to at least 512mb. About JVM tunning you can read here: https://apacheignite.readme.io/docs/jvm-and-system-tuning BR, Andrei -- Sent from: http://apache-ignite-users.70518.x6.nabble.com/
