Couchbase Server 2.0 combines the power of CouchDB with the elasticity and performance of Membase Server to create the next generation of clustered NoSQL solutions. Membase Server, with its integrated memcached caching technology, provides technology enabling dynamic cluster elasticity and sustained low-latency, high-throughput data operations. CouchDB adds indexing and querying capabilities with its incremental MapReduce views, as well as its proven append-only storage format for highly reliable data persistance. This session will show a hand-on tour of the product and explain the underlying architecture.
Package managers. Opaque bits of magic maintained by sysadmin heros no more! The registry for the node package manager (npm) is completely built in CouchDB with ease of replication in mind. This talk will explore how npm and the node.js community uses the npm-registry CouchApp and replication to make package management (and associated customization)a breeze.
MapReduce represents the way you write queries, aka 'views', in CouchDB. In this session, we will demonstrate writing map and reduce functions in Javascript, show how to call them from a client, and discuss how CouchDB executes and updates the views as the queried documents are being updated.
This session covers how to build quality MapReduce functions in practice. Using examples that leverage complex keys, groupings, you'll see this in both JavaScript with common-js modules and how to use alternate view engines.
Couchbase is schemaless, but knowing a bit about what you want in and from a document will make a world of difference when writing your MapReduce queries, designing your application, and planning for your permissions architecture. We'll dig into the beautiful freedom that comes with a schemaless database, and how to bring order to the chaos with a little pre-planning, some map/reduce view tricks, and the occasional documentation validation function.

In this talk we'll see how to build CouchApps using CouchDB, Javascript, and HTML5. We'll look at related tools such as the couchapp command ine tool, the Evently jQuery plugin, the CouchDB API jQuery plugin, the CouchApp Loader, Pathbinder, and the Mustache templating framework.
