Developing with Couchbase: Exploring Common Models and Integrations

Michael Nitschinger

Engineer, Developer Solutions

JVM Integrations

Spring Data Couchbase

• Integration with Spring Data

­ Templates

­ Repositories

­ Exception Mapping

­ also @Cacheable

• Maps POJO Entities to JSON (and back)

• Under development, M2 released (RC1 soon).

Repositories – Do this

Repositories – Get this

Repositories – Backed by Views

findByFirstname()

findAll(), count()

JavaConfig

Putting it together

There is more!

• Entity mapping (Alias keys, TTLs, @Version for optimisticconcurrency,...)

• JavaConfig and XML support

• CouchbaseTemplate for lower level access

• @View to customize Views and DesignDocuments

• @Cacheable suport for transparent caching

• Spring Boot and Spring XD integration in the works

ReactiveCouchbase

• ReactiveCouchbase

­ integrates Scala, Play and Akka

­ Very sophisticated

• i.e. Capped Collections

• N1QL Support

• Maintained by the community

• http://reactivecouchbase.org/

.NET Integrations

couchbase-aspnet

• SessionState Provider­ Allows for storing session state in Couchbase, where it will be fast to

access, replicated, persisted

Session["Message"] = "Couchbase is awesome!”;

• OutputCache Provider­ Allows for retrieving some content directly from Couchbase as a cache,

rather than executing code each time.

[OutputCache(Duration = 60, VaryByParam="foo")]

public ActionResult Time(string foo)

{

return Content(DateTime.Now.ToString());

}

General Infrastructure for ASP.NET Applications

couchbase-glimpse

• CouchbaseGlimpse package available on NuGet or listed off of getglimpse.com

­ Allows for insight into what’s happening on the back-end as you interact with your web application

Couchbase Insight, In the Browser

couchbase-model-views

• Decorate your entities to generate views for indexing the JSON behind those classes

Ruby Integrations

ActiveModel

• Allows for idiomatic Model interaction

­ in Ruby and Ruby on Rails

• Simple modeling of entities

• Rich querying

• Automatic View Management

• https://github.com/couchbase/couchbase-ruby-model

Elasticsearch Integration

Elasticsearch + Couchbase Workflow

ES Query (Criteria)

ES Result (IDs)

Couchbase MultiGet

Couchbase Result (Docs)

The Learning Portal

• Designed and built as a collaboration

between MHE Labs and Couchbase

• Serves as proof-of-concept and

testing harness for Couchbase +

Elasticsearch integration

• Available for download and further

development as open source code

https://github.com/couchbaselabs/learningportal

Dogfooding: CBUGG

• Philosophy:

­ Because all bug systems are bad and I like writing bad code.

­ Also could be CB UGG

⁃ Create bug on github, closed immediately, creates a bug on cbugg.

⁃ Pull requests send to the project, create cbugg issues tagged as pull request.

⁃ Bug references can show up as comments on the bugs.

In order to keep up with changing needs on

richer, more targeted content that is delivered

to larger and larger audiences very quickly,

data behind content driven sites is shifting to

Couchbase.

Hadoop excels at complex analytics which

may involve multiple steps of processing

which incorporate a number of different data

sources.
