16.6. Mortal and Immortal Data
16.6.1. About Data Mortality
In addition to storing entities, JBoss Data Grid allows you to attach mortality information to data. For example, using the standard
put(key, value)
creates an entry that will never expire, called an immortal entry. Alternatively, an entry created using put(key, value, lifespan, timeunit)
is a mortal entry that has a specified fixed life span, after which it expires.
In addition to the
lifespan
parameter, JBoss Data Grid also provides a maxIdle
parameter used to determine expiration. The maxIdle
and lifespan
parameters can be used in various combinations to set the life span of an entry.
