Developing a memcached Application

A number of language interfaces let applications storę and retrieve information with

memcached

sen/ers. You can write memcached applications in popular languages such as Perl, PHP, Python,

Ruby, C, and Java.

Data stored into a memcached server is referred to by a single string (the key), with storage into the

cache and retrieval from the cache using the key as the reference. The cache therefore operates

like a large associative array or hash table. It is not possible to structure or otherwise organize the

information stored in the cache. To emulate database notions such as multiple tables or composite

key values, you must use encode the extra information into the strings used as keys. For example, to

storę or look up the address corresponding to a specific latitude and longitude, you might turn those

t\MD numeric values into a single comma-separated string to use as a key.
