Horizontal scalability and distributed workloads brings enterprise 
functionality to the database that kickstarted the NoSQL movement.

At ApacheCon Europe 2014, the Apache CouchDB™ project today announced a 
Developer Preview release of its CouchDB 2.0 document database. The Developer 
Preview release brings all-new clustering technology to the Open Source NoSQL 
database, enabling a range of big data capabilities that include being able to 
store, replicate, sync, and process large amounts of data distributed across 
individual servers, data centers, and geographical regions in any deployment 
configuration, including private, hybrid, and multi-cloud. 

"The Developer Preview release of CouchDB 2.0 delivers on our goal of bringing 
Apache CouchDB to the enterprise," said Jan Lehnardt, Vice President of Apache 
CouchDB. "Flexibility and scalability are becoming increasingly important, and 
it's crucial that data can be stored wherever, accessed whenever, and processed 
however. Combined with the success of our unique sync protocol that enables 
flawless mobile-first and offline work capabilities, clustering promises to 
propel CouchDB into the core of many business." 

Apache CouchDB is the database that kickstarted the NoSQL movement. It has been 
built from the ground up with high performance and fault-tolerance in mind. 
Unlike SQL, NoSQL frees developers from having to make any decisions in 
advance, allowing data to be captured in any form, with structuring, filtering, 
and querying being done after the fact. 

In earlier versions of CouchDB, databases could be replicated across as many 
individual servers as needed, but each server was limited by vertical scaling. 
With the clustering introduced in the Developer Preview, databases can now be 
distributed across many servers, adding horizontal scaling capability to 
CouchDB. This technology works by borrowing many principles from Amazon's 
Dynamo paper, and improves the overall performance, durability, and 
high-availability of large-scale CouchDB deployments. 

Also in the Developer Preview 
Other additions in the Developer Preview include a faster database compactor, a 
faster replicator, easier setup, re-organised code for easier contributions, a 
global changes feed, and improved test coverage. This version of CouchDB also 
includes a new Web dashboard admin interface called Fauxton, with improved user 
experience design, rich query editors, and a management interface for 
replication. (A screenshot of Fauxton is available at

Beyond CouchDB 2.0 
Also announced today are plans for upcoming new features, including a 
declarative ad-hoc querying system that standardises around the de facto 
MongoDB query syntax. This feature promises to open up CouchDB to a whole new 
segment of developers familiar with SQL who want to use something that feels 
familiar and allows for casual use. 

Get Involved 
The Apache CouchDB community encourages feedback as it works towards the 2.0 
General Availability release, which is expected early 2015. Those interested in 
becoming involved with Apache CouchDB are invited to participate in or 
contribute to any of the project's three IRC channels, eight mailing lists, or 
45 Git repositories. 

Governance and Oversight 
As with all Apache products, CouchDB software is released under the Apache 
License v2.0, and is overseen by a self-selected team of active contributors to 
the project. The Apache CouchDB Project Management Committee (PMC) guides the 
Project's day-to-day operations, including community development and product 
releases. 

About Apache CouchDB™ 
Apache CouchDB is the database that kickstarted the NoSQL movement. It has been 
built from the ground up with high performance and fault-tolerance in mind. 
CouchDB enables users to easily store, replicate, sync, and process large 
amounts of data, distributed across mobile devices, servers, data centers, and 
geographical regions in any deployment configuration, including private, 
hybrid, and multi-cloud environments. 

CouchDB entered the Apache Incubator in February 2008 and became an Apache 
Top-level Project in November of the same year. Visit
