// Package lru provides three different LRU caches of varying sophistication.
|
|
//
|
|
// Cache is a simple LRU cache. It is based on the
|
|
// LRU implementation in groupcache:
|
|
// https://github.com/golang/groupcache/tree/master/lru
|
|
//
|
|
// TwoQueueCache tracks frequently used and recently used entries separately.
|
|
// This avoids a burst of accesses from taking out frequently used entries,
|
|
// at the cost of about 2x computational overhead and some extra bookkeeping.
|
|
//
|
|
// ARCCache is an adaptive replacement cache. It tracks recent evictions as
|
|
// well as recent usage in both the frequent and recent caches. Its
|
|
// computational overhead is comparable to TwoQueueCache, but the memory
|
|
// overhead is linear with the size of the cache.
|
|
//
|
|
// ARC has been patented by IBM, so do not use it if that is problematic for
|
|
// your program.
|
|
//
|
|
// All caches in this package take locks while operating, and are therefore
|
|
// thread-safe for consumers.
