Secondary Indexes in Riak

Hey, “…alternate keys, one-to-many relationships, or many-to-many relationships…,” it sounds like they are playing the topic map song!

From the post:

Developers building an application on Riak typically have a love/hate relationship with Riak’s simple key/value-based approach to storing data. It’s great that anyone can grok the basics (3 simple operations, get/put/delete) quickly. It’s convenient that you can store anything imaginable as an object’s value: an integer, a blob of JSON data, an image, an MP3. And the distributed, scalable, failure-tolerant properties that a key/value storage model enables can be a lifesaver depending on your use case.

But things get much less rosy when faced with the challenge of representing alternate keys, one-to-many relationships, or many-to-many relationships in Riak. Historically, Riak has shifted these responsibilities to the application developer. The developer is forced to either find a way to fit their data into a key/value model, or to adopt a polyglot storage strategy, maintaining data in one system and relationships in another.

This adds complexity and technical risk, as the developer is burdened with writing additional bookkeeping code and/or learning and maintaining multiple systems.

That’s why we’re so happy about Secondary Indexes. Secondary Indexes are the first step toward solving these challenges, lifting the burden from the backs of developers, and enabling more complex data modeling in Riak. And the best part is that it ships in our 1.0 release, just a few weeks from now.
