Overview

Capped

Experimental

Capped backend for MongoCacheStore

Description

Experimental do not use… yet.

This should only be used if limiting the size of the cache is of great concern. Entries are flushed from the cache on a FIFO basis, regardless of the entries expiration time.

Delete operations set an entry to expired, but it will not be flushed until it is automatically removed by MongoDB.
