| The `cache.xml` examples show configuration of region and server subscription queue overflows. |
| |
| <a id="overflow_config_examples__section_FD38DA72706245C996ACB7B23927F6AF"></a> |
| 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: |
| |
| ``` pre |
| <!-- Overflow when the region goes over 10000 entries --> |
| <region-attributes> |
| <eviction-attributes> |
| <lru-entry-count maximum="10000" action="overflow-to-disk"/> |
| </eviction-attributes> |
| </region-attributes> |
| ``` |
| |
| Configuration of server's client subscription queue overflow: |
| |
| ``` pre |
| <!-- Overflow the server's subscription queues when the queues reach 1 Mb of memory --> |
| <cache> |
| <cache-server> |
| <client-subscription eviction-policy="mem" capacity="1"/> |
| </cache-server> |
| </cache> |
| ``` |
