Generally speaking, I love randomized algorithms, but there is one I love particularly since even after you understand how it works, it still remains magical from a programmer point of view. It accomplishes something that is almost illogical given how little it asks for in terms of time or space. This algorithm is called HyperLogLog, and today it is introduced as a new data structure for Redis. Co
Super easy setup Provisioning an instance with openredis is fast and easy. We handle all the heavy lifting for you. Automated backups Data storage is always painful: you have to make sure that you run backups and that backups are always working. We offer hourly backups that are stored in S3, and you can access them anytime from your dashboard. Disaster recovery plan For cases when imminent storms—
Learn several Redis patterns by building a Twitter clone This article describes the design and implementation of a very simple Twitter clone written using PHP with Redis as the only database. The programming community has traditionally considered key-value stores as a special purpose database that couldn't be used as a drop-in replacement for a relational database for the development of web applic
Part of my work on Redis is reading blog posts, forum messages, and the twitter time line for the "Redis" search. It is very important for a developer to have a feeling about what the community of users, and the community of non users, think about the product he is developing. And my feeling is that there is no Redis feature that is as misunderstood as its persistence. In this blog post I'll do an
前回、多機能高速なキーバリューストアRedisをインストールして、本体ソースについてきたクライアントで値を保存したり取得したりしてみました。 前回の記事 今回は同じ事をRubyからやってみたいと思います。 あと、最後の方でRuby+Redisでツイッターのタイムライン的なものを表現してみたり。 インストール ライブラリはgemで提供されています。 $ gem install redis使い方 Redis.newでオブジェクトを生成して、あとはRedisのコマンド(http://redis.shibu.jp/commandreference/index.html)にならってメソッドが実装してあるようです。 ローカルホストの標準ポートでRedisが動いている場合 redis = Redis.new ホストとポートを指定する場合 redis = Redis.new(:host => "10.0.
