Chapter 9. The Memcached Interface
9.1. About the Memcached Protocol
Memcached is an in-memory caching system used to improve response and operation times for database-driven websites. The Memcached caching system defines a text based protocol called the Memcached protocol. The Memcached protocol uses in-memory objects or (as a last resport) passes to a persistent store such as a special memcached database.
JBoss Data Grid offers a server that uses the Memcached protocol, removing the necessity to use Memcached separately with JBoss Data Grid. Additionally, due to JBoss Data Grid's clustering features, its data failover capabilities surpass those provided by Memcached.
