Hi, A node has to join the cluster to receive/register for messages/events.
You can store events: https://ignite.apache.org/releases/latest/javadoc/org/apache/ignite/spi/eventstorage/memory/MemoryEventStorageSpi.html On every node join, replay the events stored. see: https://ignite.apache.org/features/messaging.html https://apacheignite.readme.io/docs/events example: https://github.com/apache/ignite/blob/master/examples/src/main/java/org/apache/ignite/examples/datagrid/CacheEventsExample.java Thanks, Alex -- Sent from: http://apache-ignite-users.70518.x6.nabble.com/
