Med NoSQL-databaser blir det enklare för IT-experter och utvecklare att hantera den aldrig sinande strömmen av nya datatyper och modeller. Databaserna är extremt effektiva på att hantera oförutsägbara data – ofta med blixtsnabb frågekörning – och förenklar databasmigreringen av befintliga NoSQL-arbetsbelastningar till molnet.

NoSQL databases fall into four main categories: Key value Stores — Riak, Voldemort, and Redis. Wide Column Stores — Cassandra and HBase. Document databases — MongoDB. Graph databases — Neo4J and HyperGraphDB. The words to the right hand side are examples of the types of NoSQL database types.
In March 2009 it became an Apache Incubator project. On February 17, 2010 it graduated to a top-level project. Facebook developers named their database after the Trojan mythological prophet Cassandra, with classical allusions to a curse on an oracle. Facebook’s latest project is a NoSQL database called Apollo that provides online low latency hierarchical storage. The details of the database project were revealed at QCon New York on Wednesday by Jeff Johnson, a software engineer in Facebook’s Core Data group.
The Apache Cassandra database is the right choice when you need 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. Cassandra's support for replicating across multiple datacenters is best-in-class, providing lower latency for your

Is it SQL or NoSQL? How has FB database architecture evolved over the last 15+ years? So, FB used its significant engineering might to essentially create a custom database query layer that abstracted the underlying sharded MySQL databases. In doing so, it forced its developers to completely give up on SQL as a flexible query API and adopt TAO’s custom NoSQL API. MySQL is the primary database used by Facebook for storing all the social data. It started with the InnoDB MySQL database engine & then wrote MyRocksDB, which was eventually used as the MySQL Database engine.

The benefits of NoSQL databases (NoSQL DBs) NoSQL databases help IT pros and developers manage the new challenges of ever-expanding diversity of data types and models and are highly effective at handling unpredictable data, often with blazing-fast query speeds. They also provide a smooth database migration to the cloud for existing NoSQL workloads. There are a variety of NoSQL data stores in use at Facebook. Of the well known public NoSQL solutions: * HBase is used for messages and monitoring * Hadoop/hive is the primary big data analytical store * Memcached is still heavily used as well Back in 2014, Jeff Johnson, a Facebook representative announced the introduction of Apollo at the QCon New York.
