NoSQL Data Modeling Techniques
NoSQL databases are often compared by various non-functional criteria, such as scalability, performance, and consistency. This aspect of NoSQL is well-studied both in practice and theory because specific non-functional properties are often the main justification for NoSQL usage and fundamental results on distributed systems like the CAP theorem apply well to NoSQL systems. At the same time, NoSQL
NoSQLとしてMySQLを使うDeNAが、memcachedよりも高速な75万クエリ／秒を実現
モバゲーで知られるDeNAは、バックエンドデータベースにNoSQLを使っていません。なぜか？ それはMySQL/InnoDB 5.1の環境で秒間75万クエリという、多くのNoSQLでも実現できないような高性能を実現しているから。DeNAの松信嘉範（まつのぶよしのり）氏は、自身のブログにこんな内容のエントリ「Using MySQL as a NoSQL - A story for exceeding 750,000 qps on a commodity server」（英語）をボストしています。 Yoshinori Matsunobu's blog: Using MySQL as a NoSQL - A story for exceeding 750,000 qps on a commodity server 松信氏が指摘するように、大規模なネットサービスを提供している企業の多くは分散環境で
NoSQL Databases List by Hosting Data - Updated 2025
In April 2020, NoSQL-Database.org joined forces with hostingdata.co.uk. These two websites and the teams responsible for their creation will now work together. The decision was made after the owners recognized that they have a common objective – helping people in the UK (and beyond) understand web hosting and all its intricacies, including NoSQL databases. This list is updated monthly. We’ve teste
NoSQL Twitter Applications
Everyone is building these days a Twitter-like or Twitter-related project using some NoSQL solution. I guess they can use as a ‘scientific’ explanation for these experiments Nati Shalom’s (Gigaspaces) great ☞ post on the common principles behind NoSQL alternatives (the post was inspired by his talk at QCon on building a scalable Twitter application. The presentation is embedded below). MusicTweets
Learning NoSQL from Twitter's Experience
Leaving aside the tons of NoSQL Twitter applications — and if that is not enough here are more NoSQL-based Twitter apps and even more, Twitter seems to be having a lot of fun (nb read work and innovation) in the NoSQL space. It all started with the problem of handling big data in real-time. Nick Kallen’s (@nk) slides below are explaining the problems faced and the way Twitter tackled them: Then it
NoSQL at Twitter (NoSQL EU 2010)
The document discusses Twitter's use of NoSQL databases and big data analytics, detailing the challenges of managing and analyzing the massive amounts of data generated by its users, which can reach 7 TB per day. It highlights the implementation of technologies like Scribe for data collection, Hadoop for storage and analysis, and Pig for simplifying data processing tasks. The presentation emphasiz

NoSQLの本命となるか？ memcachedの開発者らが新たなオープンソースプロジェクト「membase」を立ち上げ | OSDN Magazine
Webインフラ企業の米NorthScaleは6月23日（米国時間）、オープンソースのNoSQLプロジェクト「membase.org」を立ち上げたことを発表した。プロジェクトのサイトでは、「Membase 1.6」ベータ1のバイナリとソースコードを公開している。 NorthScaleは分散メモリキャッシュシステム「memcached」の主要開発者が立ち上げたベンチャー企業で、memcachedをベースにした「NorthScale Membase Server」や「NorthScale Memcached Server」などの製品を開発・提供している。今回、membaseの早期ユーザーである米Zynga、韓国NHNの2社と共に、オープンソースプロジェクトとしてmembase.orgを立ち上げた。今後は、membase.orgをオープンソースプロジェクトとし、商用版としてMembase Serv
Four Reasons to Love CouchDB, Part 1 | A.J. Brown's Blog
Other articles in this series: Part 2 I’ve been sensing a lot of hype around CouchDB lately, and I recently decided to give it a try. After about ~30 hours of working with it, and a successful prototype of a project driven by CouchDB (and special shout-out to Zend Framework and Phly), I think I may have found a favorite new toy to share it with you. This will be a multi-part series with each artic

NoSQL - Wikipedia
"Structured storage" redirects here. For the Microsoft technology, see COM Structured Storage. NoSQL (originally meaning "Not only SQL" or "non-relational")[1] refers to a type of database design that stores and retrieves data differently from the traditional table-based structure of relational databases. Unlike relational databases, which organize data into rows and columns like a spreadsheet, No
Cassandra @ Twitter: An Interview with Ryan King
There have been confirmed rumors[1] about Twitter planning to use Cassandra for a long time. But except the mentioned post, I couldn’t find any other references. Twitter is fun by itself and we all know that NoSQL projects love Twitter. So, imagine how excited I was when after posting about Cassandra 0.5.0 release, I received a short email from Ryan King, the lead of Cassandra efforts at Twitter s
