Caching database queries with Node.js

Question

Is there an implementation of database (mysql) query caching written purely in Node.js?

I\'m writing a Node web app and was planning on caching queries with memcache

Answer 1

I went ahead and wrote a caching solution for private use that stored the data in a shared object. This wasn't really query caching, it stores specific results instead of raw sql results ordered by hashes, but it kept what I needed in memory and was ridiculously easy to write.

Since I originally asked this question a number of node caching solutions have emmerged:

1. ptarjan/node-cache
2. tcs-de/nodecache
3. vxtindia/node-cache
4. mape/node-caching

I haven't used any of these but one of them might well be of use to someone else.

There are now also redis and memcached clients for node.

Answer 2

You can definitely implement something like this in node, and it could be an interesting project, but it depends on your needs. If you're just doing this for a hobby project, by all means, build a caching layer in node and try it out. Let us know how it goes!

If this is for production use, then I would recommend sticking to the established caching layers (memcached, redis, etc) as they have already gone through all of the growing pains associated with building a scalable caching system.

Answer 3

I have written a node.js module that performs MySQL query caching using memcached.

The module is named Memento and is available at https://www.npmjs.com/package/memento-mysql

Enjoy!
