Slides- Moving from a Relational Database to Riak

January 3, 2013

Most teams considering using Riak come from a relational database background. From our webcast on moving from relational to Riak, the below slide deck covers an overview of Riak, how the architecture differs from a relational approach, the advantages for scaling and development, and what’s different about application building and database operating in a non-relational world. We also include a few stories of Riak users who replaced MySQL or added Riak to the mix.

Yokozuna Pre-release 0.2.0 Now Available

December 31, 2012

Happy Holidays from all of us here at Basho. We’ve got some new code to help you ring in the new year. Ryan Zezeski and others have been hard at work on Yokozuna, the next generation of Riak Search that marries Riak with Apache Solr.

The latest pre-release, 0.2.0, was just tagged, and there’s plenty to be excited about for those of you who are interested in test-driving the code. In addition to various bug fixes, some of the new features include:

  • Active Anti Entropy Support – Automatic background processing that seeks out and rectifies divergences between data stored in Riak and indexes stored in Yokozuna.
  • Benchmark Scripts – A pre-built collection of benchmarking scripts for automating performance testing.
  • Sibling Support – When enabled, Yokozuna will now index all object versions. It will also handle index cleanup upon sibling resolution.

The full release notes are up on the GitHub repo.

Contributors

Commits in this release came from Ryan Zezeski, Eric Redmond, and Dan Reverri. Mark Steele also reported a few issues that were fixed in this release.

Use Yokozuna

Remember that this is alpha software, and won’t be officially supported by Basho until a future release. That said, Ryan and the team are actively looking for beta testers with use cases that might be appropriate for Yokozuna. If you’re in the market for scalable, distributed full-text search, join the Riak Mailing List and start asking questions.

There’s a pre-built Yokozuna AWS AMI (ami-8b8d03e2) with the latest changes that’ll make it easy to take Yokozuna for a test drive.

And if you’re looking for a high-level introduction to Yokozuna, take 30 minutes to watch Ryan’s RICON2012 talk or browse the matching slide deck.

Enjoy.

From Relational to Riak- Advantages, Tradeoffs and Considerations

December 19, 2012

We work with many people building platforms and applications on Riak that have traditionally lived on relational systems. The switch to Riak can be driven by the needs of greenfield applications and growing data volumes, business requirements around scale and availability, or the desire for operational ease and multi-site replication.

Some of the most common questions we get are from teams with a primary background in MySQL, Oracle Database or other relational systems wondering about the advantages and tradeoffs of moving to Riak. To address these common questions, we’ve written up an introductory guide on moving from relational to Riak. In it, we cover:

  • Scalability benefits of Riak, including an examination of limitations around master/slave architectures and sharding, and what Riak does differently
  • A look at the operational aspects of Riak and where they differ from relational approaches
  • Riak’s data model and benefits for developers, as well as the tradeoffs and limitations of a key/value approach
  • Migration considerations, including where to start when migrating existing applications to Riak
  • Riak’s eventually consistent design, how it differs from a strongly consistent design, and things you need to know about handling data conflicts in Riak
  • Multi-site replication options in Riak

You can download the paper here, and when you’re ready to dive deeper, check out our online documentation with more information on Riak, building applications on it, and our commercial products.

Riak Enterprise at Velti

December 3, 2012

In 2009, mobile marketing and advertising technology provider Velti had a good (but challenging) problem on their hands. Their technology, which allows people to interact with their TV by voting, giving feedback, participating in contests, etc., had taken off. It had been adopted by nearly all of the TV broadcasters in the UK and three of the UK’s five mobile operators. As more customers began using their technology, Velti saw quick growth in (inherently spikey) traffic. Their 2003-era .NET, SQLServer platform was becoming a concern.

Because the team at Velti had been working with Erlang (what Riak is written in), in 2010 they brought in Erlang Solutions to help them architect their next generation platform. Riak was chosen for the database, and an early version of Multi-Data Center replication in Riak Enterprise was used to build two geographically separated sites to minimize potential catastrophic outages.

Velti’s new mGageTM platform is now running on 18 servers across two data centers (nine nodes in each data center), with each server running both Erlang applications as well as Riak. We’re pleased to pass along reports that the platform is redundant, queue behavior has significantly improved (especially for large queue populations), and that after Velti moved to Riak 1.2, they saw noticeable disk space utilization thanks to improvements in merge management.

Markus Kern, VP Technology at Velti summarizes, “We operate a 24/7 service for over 140 customers. We cannot afford a single minute of downtime. Riak gives us the ability to meet and exceed our requirements for scale, data, durability, and availability.” Woot!

For more details on Velti’s experience, see our case study Highly Available Mobile Platform With Riak.

The Future of Distributed Systems (RICON Video Roundup)

November 22, 2012

With a growing community understanding of distributed systems architectures, where is the field evolving? How are Riak and other Dynamo-inspired databases handling complex data structures and meeting demands for stronger consistency and more queriability? This blog highlights three talks from last month’s RICON that tackle these questions.

Advancing Distributed Systems – Eric Brewer

In this keynote talk, Dr. Eric Brewer, author of a theorem that helped kick off the NoSQL movement, talks about the challenges facing distributed systems today. Beginning with some historical context–“SQL vs. NoSQL is not really a new religious war, it’s actually the latest round of a very old religious war”– Dr. Brewer walks us through the advantages and disadvantages of top-down (relational) and bottom-up (NoSQL) worldviews, his work at Google, and his thoughts on where next generation databases are headed.

Bringing Consistency to Riak – Joseph Blomstedt

With regard to the CAP Theorem, Riak is an eventually-consistent database with AP semantics. But, this may soon change. In this talk, Basho engineer Joseph Blomstedt presents, for the first time, on-going R&D at Basho to add true strongly-consistent/CP semantics to Riak.

Data Structures in Riak – Sean Cribbs and Russell Brown

Since the beginning, Riak has supported high write-availability using Dynamo-style multi-valued keys – also known as conflicts or siblings. The tradeoff for this type of availability is that the application must include logic to resolve conflicting updates. This ad hoc resolution strategy is error-prone and can result in surprising anomalies. In this talk, Basho engineers Sean Cribbs and Russel Brown present recent work done to address these issues by adding convergent data structures to Riak.
