InfoQ: グラフデータベース、NOSQL、Neo4j
VoldemortやTokyo Cabinetといったキー/バリューシステムにおけるモデリングの最小単位はキー/バリューペアになる。そして、BigTableやそのクローンでは可変数の属性をもつタプルに、CouchDBやMongoDBといったドキュメントデータベースではドキュメントになる。これに対しグラフデータベースでは、データセット全体をひとつの巨大な高密度ネットワーク構造としてモデル化する。 ここではNOSQLデータベースにおける2つの興味深いポイント、スケーラビリティと複雑さについて詳しく説明する。 1. スケーラビリティ CAP: ACID 対 BASE 従来のデータベースシステムのほとんどは、トランザクションに基づいてデータの完全性を保証する。トランザクションを使うことで、データ管理のあらゆる状況において、データの一貫性を確保している。こうしたトランザクションの性質は、ACID（A
Apache Cassandra | Apache Cassandra Documentation
What is Apache Cassandra? Apache Cassandra is an open source NoSQL distributed database trusted by thousands of companies for scalability and high availability without compromising performance. Linear scalability and proven fault-tolerance on commodity hardware or cloud infrastructure make it the perfect platform for mission-critical data.
GitHub - etolabo/kumofs: kumofs is a scalable and highly available distributed key-value store.
Kumofs is a simple and fast distributed key-value store. You can use a memcached client library to set, get, CAS or delete values from/into kumofs. Backend storage is Tokyo Cabinet and it will give you great performance. Data is partitioned and replicated over multiple servers. Extreme single node performance; comparable with memcached. Both read and write performance got improved as servers added
GitHub - voldemort/voldemort: An open source clone of Amazon's Dynamo.
Data is automatically replicated over multiple servers across multiple datacenters. Data is automatically partitioned so each server contains only a subset of the total data Server failure is handled transparently Pluggable serialization is supported to allow rich keys and values including lists and tuples with named fields, as well as to integrate with common serialization frameworks like Protoco
