General Region Data Management

This topic links to documentation about general region data management in VMware Tanzu GemFire.

For all regions, you have options to control memory use, back up your data to disk, and discard stale data from 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. Eviction actions are triggered by space-based thresholds.

• Expiration

  Use expiration to keep data current and to reduce region size by removing stale entries. Expiration actions are triggered by time-based thresholds.

• Keeping the Cache Synchronized with Outside Data Sources

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