following stores are currently supported:
The interface CountableStore is supported by the following classes:
The interface SortableStore is supported by the following classes:
The decorator CachingDecorator exists for caching another store instance
in a Doctrine cache.
FAQ
Why not use Doctrine Cache?
Caching is not key-value storage. When you use a cache, you accept that keys may disappear for various reasons:
- Keys may expire.
- Keys may be overwritten when the cache is full.
- Keys may be lost after shutdowns.
- ...
In another word, caches are volatile. This is not a problem, since the cached data is usually stored safely somewhere else. The point of a cache is to provide high-performance access to frequently needed data.
Key-value stores, on the other hand, are persistent. When you write a key to a key-value store, you expect it to be there until you delete it. It would be a disaster if data would silently disappear from a key-value store (or any other kind of database).
Hence the two libraries fulfill two very different purposes, even if their interfaces and implementations are often similar.
The CachingDecorator actually uses a Doctrine Cache object to cache the data
of a persistent KeyValueStore.
