Overflow Configuration Examples

The cache.xml examples show configuration of region and server subscription queue overflows.

Configure overflow criteria based on one of these factors:

  • Entry count
  • Absolute memory consumption
  • Memory consumption as a percentage of the application heap (not available for server subscription queues)

Configuration of region overflow:

<!-- Overflow when the region goes over 10000 entries -->
    <lru-entry-count maximum="10000" action="overflow-to-disk"/>

Configuration of server’s client subscription queue overflow:

<!-- Overflow the server's subscription queues when the queues reach 1 Mb of memory -->
    <client-subscription eviction-policy="mem" capacity="1"/>
