General Region Data Management

For all regions, you have options to control memory use, back up your data to disk, and keep stale data out of your cache.

  • Persistence and Overflow

    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.

  • Eviction

    Use eviction to control data region size.

  • Expiration

    Use expiration to keep data current by removing stale entries. You can also use it to remove entries you are not using so your region uses less space. Expired entries are reloaded the next time they are requested.

  • Keeping the Cache in Sync with Outside Data Sources

    Keep your distributed cache in sync with an outside data source by programming and installing application plug-ins for your region.
