node-lru-addon's Introduction

node-lru-addon

This is an implementation of a simple in-memory cache for node.js, supporting LRU (least-recently-used) eviction and TTL expirations.

It was developed as an alternative to the (excellent) node-lru-cache library for use with hashes with a very large number of items. V8 normally does a good job of optimizing the in-memory representation of objects, but it isn't optimized for an object that holds a huge amount of data. When you add a very large number of properties (particularly with non-integer keys) to an object, performance begins to suffer.

Rather than rely on V8 to figure out what we're trying to do, node-lru-native is a light wrapper around std::unordered_map from C++11. A std::list is used to track accesses so we can evict the least-recently-used item when necessary.

Based on the node-hashtable library by Issac Wagner.

Because original code is no longer maintained, I update this code and publish it as a new name lru-addon

Usage

Install via npm:

$ npm install lru-addon

Then:

var LRUCache = require('lru-addon');
var cache = new LRUCache({ maxElements: 1000 });
cache.set('some-key', 42);
var value = cache.get('some-key');

If you'd like to tinker, you can build the extension using node-gyp:

$ npm install -g node-gyp
$ node-gyp configure
$ node-gyp build

Benchmark

See benchmark folder for a extremly simple test. You can do it by yourself aslo.

Configuration

To configure the cache, you can pass a hash to the LRUCache constructor with the following options:

var cache = new LRUCache({

  // The maximum number of items to add to the cache before evicting the least-recently-used item.
  // Default: 0, meaning there is no maximum.
  maxElements: 10000,

  // The maximum age (in milliseconds) of an item.
  // The item will be removed if get() is called and the item is too old.
  // Default: 0, meaning items will never expire.
  maxAge: 60000,

  // The initial number of items for which space should be allocated.
  // The cache will resize dynamically if necessary.
  size: 1000,

  // The maximum load factor for buckets in the unordered_map.
  // Typically you won't need to change this.
  maxLoadFactor: 2.0

});

API

set(key, value)

Adds the specified item to the cache with the specified key.

get(key)

Returns the item with the specified key, or undefined if no item exists with that key.

remove(key)

Removes the item with the specified key if it exists.

keys([subkey])

Get all keys from cache. If subkey parameter is present, then it returns only keys that contain subkey.

clear()

Removes all items from the cache.

size()

Returns the number of items in the cache.

stats()

Returns a hash containing internal information about the cache.

node-lru-addon's Issues

Module not working

Example given in readme not working:

var LRUCache = require('lru-addon');
var cache = new LRUCache({ maxElements: 1000 });
cache.set('some-key', 42);
var value = cache.get('some-key');

Node version 6.8.1. The original implementation https://www.npmjs.com/package/lru-native working well.

Fails with error:

node index.js
(node) v8::ObjectTemplate::Set() with non-primitive values is deprecated
(node) and will stop working in the next major release.
