Pioneering Open Source database that scales from Big Data to Mobile in use at 
Apple, Deutsche Telekom, DHL, and IBM, among many others. 

Forest Hill, MD —20 September 2016— The Apache Software Foundation (ASF), the 
all-volunteer developers, stewards, and incubators of more than 350 Open Source 
projects and initiatives, announced today the availability of Apache® CouchDB™ 
v2.0, the database that scales from Big Data to Mobile. 

Apache CouchDB is widely recognized as the pioneering NoSQL database that first 
brought the simplicity of JSON and HTTP to the database world. CouchDB's 
seamless multi-master synchronisation make it ideal for Big Data applications 
and mobile devices. 

"CouchDB 2.0 finally fulfills the project’s original vision to bring reliable 
data sync to Big Data and Mobile in one seamless solution," said Jan Lehnardt, 
Vice President of Apache CouchDB. "The team has been working tirelessly to make 
that vision a reality, and we're extremely proud of the resulting 2.0 release." 

Apache CouchDB 2.0 is the result of the donation and subsequent merger of IBM 
Cloudant's BigCouch project to The Apache Software Foundation, giving the 
project significant features and production-ready code in one go. CouchDB 2.0 
features include: 

- Built-in clustering for Big Data-scale and high-availability (based on the 
Amazon Dynamo paper); 
- 99% API compatibility with previous versions (most applications will continue 
to just work); 
- "Mango", the new, developer-friendly querying language; 
- Significant performance improvements in all areas, specifically replication 
and compaction; and 
- Completely rewritten and modern admin interface. 

Apache CouchDB is in use at an array of global organizations such as Apple, 
Deutsche Telekom, and DHL, among many others. It is at the core of the emerging 
Offline First movement (as identified on the ThoughtWorks Radar in November 
2015) with its cross-project Couch Replication Protocol implemented by 
independent sister-projects such as a) PouchDB (targeting in-browser as well as 
Node.js JavaScript environments), b) Couchbase Lite (for iOS and and Android), 
and c) Cloudant Mobile Sync. This ecosystem of projects and products allows 
developers to build offline capable Web- and native applications that provide a 
superior user experience, even in the face adverse network connectivity. 

CouchDB was instrumental in providing offline-first applications in the 
2014-2015 Ebola outbreak in West Africa, allowing first-responders to help more 
people more efficiently, including launching an Ebola vaccination trial in 
Sierra Leone. No other technology was suited to face the adversity of the lack 
of network infrastructure and a challenging human crisis spanning five 

In addition, CouchDB drives innovation at industry giants like IBM, through 
their Cloudant acquisition as the core of its Cloud Data Services portfolios, 
solving Big Data as a Service for startups and the enterprise. 

"CouchDB 2.0 is the result of several years of hard work, bringing Cloudant's 
clustering code back into the project from which it sprang," said Robert 
Newson, member of the Apache CouchDB Project Management Committee and Senior 
Database Engineer for Cloudant, IBM. "2.0 reinvigorates the CouchDB project 
with new features and better performance. I hope the CouchDB community is as 
thrilled as I am to reach this milestone in our journey and hope many of you 
will be active participants in the journey ahead." 

"CouchDB 2.0 really takes CouchDB to the next level. The new Fauxton interface 
is gorgeous, and the long-awaited debut of real clustering should satisfy any 
scaling needs," said Nolan Lawson, Web Platform PM at Microsoft Edge and 
PouchDB project maintainer. "And of course, we've been making a lot of effort 
on PouchDB to ensure it stays compatible – CouchDB 2.0 and PouchDB are a solid 
combination for modern Web development." 

"Using Apache CouchDB we can focus developing features on our cross platform 
scenario, without the high and unpredictable cost of implementing our own 
sync," said Dr. Marten Schönherr, CTO of immmr GmbH, 100% subsidiary of 
Deutsche Telekom AG. "With CouchDB 2.0, replication performance will be vastly 

"We encourage everyone interested in CouchDB to have a look what we have to 
offer with version 2.0, and we are looking forward to many success stories of 
existing users upgrading," added Lehnardt.
