Chapter 13. Expiration

13.1. About Expiration

JBoss Data Grid uses expiration to attach one or both of the following values to an entry:
  • A lifespan value.
  • A maximum idle time value.
Both the life span and maximum idle time values are assigned the default value -1 when created.
Expired entries, unlike evicted entries, are removed globally, which removes them from memory, cache stores and the cluster.
