Lite Cluster Members
Since Payara Micro 184.108.40.206
You may specify on the command line using
--lite option, or through the API,
that a Payara Micro Community instance is a lite instance. Then the Payara Micro instance
will join the cluster but will not store any clustered data; for example web
session data or JCache data. This is very useful for a number of scenarios.
You can create a cluster topology whereby a web application is hosted in a number of Payara Micro instances and the garbage collection ergonomics for these instances are tuned for throughput. In addition, a number of Payara Micro instances can be in the cluster with no applications deployed and these instances can be tuned for long-lived web session data. In this case, the web application instances could be designated as lite cluster members to make sure no web session data is stored within their JVMs.
|Lite members can also be used purely if you want a clustered Payara Micro Community instance to join the same cluster and receive CDI events or clustered events, but without storing any data.|
