Example of SQL databases: MySQL, Oracle, MS-SQL, SQLite. Examples of NoSQL databases: MongoDB, Apache CouchDB, Redis, HBase. According to Purdy, for ad hoc queries, joins, updates, relational databases tend to be faster than “NoSQL type databases” for most use cases. “The reason that NoSQL is useful is that many applications can be built avoiding those particular use cases, and can instead focus on using a very small set of database functionality; for example, applications can perform all data access and modification using primary key-based operations in order to optimize for a NoSQL K/V store,” he noted Speaking at QCon New York on Wednesday Jeff Johnson, from the core data group at Facebook, announced Apollo, Facebook’s Paxos-like NoSQL database. Written in C++11 on top of the Apache Thrift 2 NoSQL databases often make tradeoffs by relaxing some of the ACID properties of relational databases for a more flexible data model that can scale horizontally. This makes NoSQL databases an excellent choice for high throughput, low-latency use cases that need to scale horizontally beyond the limitations of a single instance. Performance A NoSQL database provides a mechanism for storage and retrieval of data that is modeled in means other than the tabular relations used in relational databases.
