Deprecated feature: The partitioning facility (WPF) feature is deprecated. You can configure partitioning with WebSphere eXtreme Scale.


Partition activation reaction times

A coordinator manages the route tables of all the partitions it is designated to host (based upon a hashing algorithm). Assume there is a single coordinator for 20,000 partitions. When the set of running Java™ Virtual Machine (JVM) changes, the lone coordinator will evaluate the policy for all 20,000 partitions. It will then send activation and deactivation messages to the surviving set of JVMs in the cell depending on the policy, which, with a single coordinator, could take an inordinate amount of time. More coordinators allow for this work to be performed by multiple machines in parallel, thereby improving the reaction time of the cell in the event of partition failures.
