Package org.apache.polygene.cache.memcache Description

Memcache EntityStore CachePool.

Memcache has no namespace support. In addition to that, the protocol disallow key listing.

The CachePool contract is to drop a cache once all of its references have been returned.

Therefore, all keys are prefixed, that way;

cacheId.cacheInstanceId.key

In other words and for a given cacheId, once all references of the Cache are returned to the CachePool, the next fetchCache(..) invocation will generate a new Cache instance identifier and hence use different prefixed keys.

All this allow the Memcache EntityStore CachePool to conform to the CachePool contract despite limitations of the Memcache protocol.
