In addition to the disk stores you specify, Pivotal GemFire has a default disk store
that it uses when disk use is configured with no disk store name specified. You can modify
default disk store behavior.
Designing and Configuring Disk Stores
You define disk stores in your cache, then you assign them to your regions and queues by setting the disk-store-name attribute in your region and queue configurations.
Disk Store Configuration Parameters
You define your disk stores in <disk-store> subelements of your cache declaration in cache.xml. All disk stores are available for use by all of your regions and queues.
Modifying the Default Disk Store
You can modify the behavior of the default disk store by specifying the attributes you want for the disk store named "DEFAULT".
