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.

  • 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.
