An Oracle White Paper February 2011 Hadoop and NoSQL Technologies and the Oracle Database Hadoop and NoSQL Technologies and the Oracle Database Dis claimer The following is intended to outline our general product direction. It is intended for information purposes only, and may not be incorporated into any contract. It is not a commitment to deliver any material, code, or functionality, and should not be relied upon in making purchasing decisions. The development, release, and timing of any features or functionality described for Oracle‟s products remains at the sole discretion of Oracle. Hadoop and NoSQL Technologies and the Oracle Database 2 Introdu ction Innovation in the database software industry continues to be extremely vibrant. In just the last couple of years, new scalability capabilities have revolutionized the performance that database systems can deliver. These include the use of very large, multi-terabyte flash memories; compression which can dramatically increase the amount of data cached in memory and the speed of disk scans for large queries; and the movement of select database logic into storage to speed functions such as row selection, compression, encryption, and more. For Oracle, this has culminated in Exadata which is an integrated software and hardware product incorporating all of these new innovations in a scale-out architecture that effectively provides unlimited scalability for all types of applications. The world of open source database technology has also been evolving rapidly. In this paper we will focus on two relatively new developments: Hadoop (MapReduce) and NoSQL. The common goal for both is massive scalability and support for what is called “Big Data”, i.e., environment...
