You can persist data on disk for backup purposes and overflow it to disk to free up memory without completely removing the data from your cache.
Note: This supplements the general steps for managing data regions provided in Basic Configuration and Programming.
All disk storage uses VMware Tanzu GemFire Disk Storage.
To use Tanzu GemFire persistence and overflow, you should understand how they work with your data.
Plan persistence and overflow for your data regions and configure them accordingly.
cache.xml examples show configuration of region and server subscription queue overflows.
