Package geronimo-jcache-1.0-api: Information

Caching is a tried and true method for dramatically speeding
up applications. Applications often use temporary data which
are expensive to create, but have a lifetime over which they
can be reused. For example, a servlet might create a web
page from data obtained from multiple databases, network
connections, and expensive computations; the sets of data
might be reusable over the same or different periods of time.
The JCACHE specification standardizes in process caching of
Java objects in a way that allows an efficient implementation,
and removes from the programmer the burden of implementing
cache expiration, mutual exclusion, spooling, and cache
consistency.
