New Redis Libraries

Silver: database cacher, indexer and searcher

Probably because Silver was released by a publisher, this new open source library got some press today:

Enter Silver. Silver is designed to be a simple, lightweight wrapper for all your calls to a database that you want to cache or index with Redis. It is completely database/web-service agnostic so you should be able to use if for anything you can imagine caching.

Couple of thoughts about this new Ruby library:

• it is not a transparent caching layer that can be used in your application. Basically you’ll have to rewrite your app to use it.
• there is not way to update the cache
• the indexer is — in their own words — “stupidly simple fuzzy text search”

Project is hosted on GitHub.

redis-store: Redis-backed Tomcat session store

Definitely not benefiting from the same media buzz, Jonathan Leibiusky pushed to GitHub a Redis-backed Tomcat session store. Plugging this into your Tomcat would require just updating the conf/server.xml:

<Manager className="org.apache.catalina.session.PersistentManager" saveOnRestart="true" maxActiveSessions="1" minIdleSwap="1" maxIdleSwap="1" maxIdleBackup="1">
    <Store className="org.apache.catalina.session.RedisStore" 
        host="localhost"
        port="6379"
        password="something"
        database="0"
    />
</Manager>

Tomcat default session store is disk, so if your app is a heavy session users, you’ll probably see a boost in performance^[1].
