Release 12cR126.96.36.199 Enterprise Edition, 2014-07-14 01:11:18 UTC
Oracle NoSQL Database is a distributed key-value store capable of scaling horizontally to handle very large amounts of data.
Oracle NoSQL Database is compatible with Java SE 7 and later, and has been tested and certified against Oracle JDK 7u51. We encourage you to upgrade to the latest Java releases to take advantage of the latest bug fixes and performance improvements.
Attempting to use this release with a version of Java earlier than Java 7 will produce an error message similar to:
Exception in thread "main" java.lang.UnsupportedClassVersionError: oracle/kv/impl/util/KVStoreMain : Unsupported major.minor version 51.0
This is release 12cR188.8.131.52 Enterprise Edition of Oracle NoSQL Database. It follows major release 3.0.5, patch release 3.0.9, previous major release 2.0.23, minor release 2.1.8, and patch releases 2.1.19, 2.1.24, 2.1.54, and 2.1.57.
This release of Oracle NoSQL Database adds several new features including user/password authentication and network security, secondary zones, and support for typed data, a tabular data model, and secondary indexes on table fields. For a complete listing of all the changes made to Oracle NoSQL Database for this release (including all bug fixes) see the change log.
Support for password-based authentication of NoSQL clients and for secure communications using SSL to both the CE and EE versions of the product. New features include:
- A security configuration utility to configure and add security to a new or existing Oracle NoSQL Database installation.
- Authentication methods to provide password authentication for users and systems.
- Encryption of data on the network to prevent unauthorized access to that data.
- External password storage to support unattended application start-up. Passwords may be stored on disk. The EE version of the product also includes the ability to use the Oracle Wallet mechanism for password storage.
- Security policies for ensuring a secure environment.
This feature is described in greater depth in the Security Guide, as well as in the Administrators Guide and product Javadoc.
Support for secondary zones has been added.
Zone is the new name for datacenter, with the new name meant to clarify that these node groupings may not always coincide with physical data centers. A zone is a collection of nodes that have good network connectivity with each other and have some level of physical separation from nodes in other zones.
The new secondary zone feature permits the deployment of zones which can be used to make a copy of the data available at a distant location, or to maintain an extra copy of the data to increase redundancy or read capacity.
This feature is described in greater depth in the Administrators Guide.
The new Table API includes a set of data types and a tabular data model using those types. It lets you manipulate data using a tables metaphor, which organizes data in columns. An unlimited number of subtables are supported by this API. It is possible to create secondary indices to improve query speeds against your tables.
Tables and indexes are defined using the administrative CLI and accessed via programmatic API. The data CLI has been enhanced to perform operations on tables and indexes as well. The API is documented in the Oracle NoSQL Database javadoc, and is found primarily in the oracle.kv.table package.
It is possible to define tables that overlay data created with NoSQL DB Release 2 if that data was created using a conforming Avro schema. This overlay is required in order to create secondary indexes on conforming Release 2 data.
This feature is described in greater depth in the Getting Started with the Tables API guide.
This release of Oracle NoSQL Database comes in three distributions: Community Edition (CE), Enterprise Edition (EE), and Client.
The CE version is open source. It ships with source code and is released under the Affero General Public License (aGPL v3). It includes the client and server distribution, but does not include some server features.
The EE version does not include source code and it ships with an Oracle license. The EE version includes the client and server distribution, and includes several features not found in the CE version: SNMP support for monitoring the store, Oracle External Tables support, and Oracle Wallet support for external password storage.
The Client version is open source. It ships with source code and is released under the Apache 2.0 License (Apache 2.0). The Client version only contains the implementation of the client API, which may be used to access servers running under either CE or EE.
In the Community Edition, the build.xml file is known to not work properly for building from source.Copyright (c) 1996, 2014 Oracle and/or its affiliates. All rights reserved.
