Couchbase Issues Developer Preview

NoSQL database specialist Couchbase has released a developer preview of the Couchbase Server 2.0 document-oriented NoSQL database. The new release combines the "elastic data management" capabilities of its own Membase Server technology with the distributed indexing and querying capabilities of Apache CouchDB.

Claiming to have produced "the most widely deployed" open source document database, Couchbase describes its offering as "bullet-proof" NoSQL database technology.

As the new foundational data storage technology for Couchbase 2.0, CouchDB is said to store data without risk of corruption, with indexing and distributed query capabilities.

Also in this stack are Membase components; these contribute towards cluster management technology, which enables linear scale-out of the data layer from one to 50 to hundreds of nodes.

"The demand for NoSQL software continues to rise and we are thrilled to be at the forefront of this dramatic shift in database technology. Today's release of Couchbase Server 2.0 provides an even more compelling solution for interactive web and mobile applications, and we're excited to get it into the hands of our users," said Bob Wiederhold, Couchbase CEO.

Forming an additional element in this product set's equation is Memcached. Built into Couchbase Server, Memcached powers in-memory caching that enables consistently low-latency and high throughput, with sub-millisecond data reads and writes.

Couchbase Server 2.0 is a member of the Couchbase family of interoperable database servers — which includes Couchbase Single Server and Couchbase Mobile.

Couchbase also announced its new Certification Program to help developers and administrators demonstrate proficiency in NoSQL database technology. The first certification exams for the new program were administered last week in conjunction with CouchConf San Francisco, the company's developer conference.
