Go library with various caching functionality

Interface

The Cache interface defines Get, Set, and Del operations, allowing cache objects to be interchanged easily.

For each of these functions, the key is a string and the value is the Object type, which contains a []byte slice with the data and a timestamp.

Functionality

MemoryCache

This is a simple cache that stores objects in memory. It has an optional object size limit and a total size limit, and will evict items when the total memory usage exceeds the limit.

DiskCache

This is a cache that stores objects on disk under a given directory. The key passed to the cache forms the path, and any subdirectories present in the path are created.

The DiskCache.ScanExisting function populates the cache's item list from the existing files in the cache directory, if desired.

MultiLevel

MultiLevel is a wrapper for multiple Caches. It starts with the first cache, and on a miss queries the upper levels. When an upper-level cache hits, the item is filled into the lower-level caches.

SplitSize

SplitSize is a wrapper for multiple Caches that delegates objects of different sizes to different caches. This can be used, for example, with two MemoryCache objects to ensure that a few large objects will not evict the smaller objects in the cache.
