Saying yes to NoSQL

As a company, The 451 Group has built its reputation on taking a lead in covering disruptive technologies and vendors. Even so, with a movement as hyped as NoSQL databases, it sometimes pays to be cautious.

In my role covering data management technologies for The 451 Group’s Information Management practice I have been keeping an eye on the NoSQL database movement for some time, taking the time to understand the nuances of the various technologies involved and their potential enterprise applicability.

That watching brief has now spilled over into official coverage, following our recent assessment of 10gen. I also recently had the chance to meet up with Couchio’s VP of business development, Nitin Borwankar (see coverage initiation of Couchio). I’ve also caught up with Basho Technologies sooner rather than later. A report on that is now imminent.

There are a couple of reasons why I have formally began covering the NoSQL databases. The first is the maturing of the technologies, and the vendors behind them, to the point where they can be considered for enterprise-level adoption. The second is the demand we are getting from our clients to provide our view of the NoSQL space and its players.

This is coming both from the investment community and from existing vendors, either looking for potential partnerships or fearing potential competition. The number of queries we have been getting related to NoSQL and big data have encouraged articulation of my thoughts, so look-out for a two-part spotlight on the implications for the operational and analytical database markets in the coming weeks.

The biggest reason, however, is the recognition that the NoSQL movement is a user-led phenomena. There is an enormous amount of hype surrounding NoSQL but for the most part it is not coming from vendors like 10gen, Couchio and Basho (although they may not be actively discouraging it) but from technology users.

A quick look at the most prominent key-value and column-table NoSQL data stores highlights this. Many of these have been created by user organizations themselves in order fill a void and overcome the limitations of traditional relational databases – for example Google (BigTable), Yahoo (Hbase), Zvents (Hypertable), LinkedIn (Voldemort), Amazon (Dynamo), and Facebook (Cassandra).

It has become clear that traditional database technologies do need meet the scalability and performance requirements of dealing with big data workloads, particularly at a scale experienced by social networking services.

That does raise the question of how applicable these technologies will be to enterprises that do not share the architecture of the likes of Google, Facebook and LinkedIn – at least in the short-term. Although there are users – Cassandra users include Rackspace, Digg, Facebook, and Twitter, for example.

What there isn’t – for the likes of Cassandra and Voldemort, at least – is vendor-based support. That inevitably raises questions about the general applicability of the key-value/column table stores. As Dave Kellog notes, “unless you’ve got Google’s business model and talent pool, you probably shouldn’t copy their development tendencies”.

Given the levels of adoption it seems inevitable that vendors will emerge around some of these projects, not least since, as Dave puts it, “one day management will say: ‘Holy Cow folks, why in the world are we paying programmers to write and support software at this low a level?'”

In the meantime, it would appear that the document-oriented data stores (Couchio’s CouchDB, 10gen’s MongoDB, Basho’s Riak) are much more generally applicable, both technologically and from a business perspective. UPDATE – You can also add Neo Technology and its graph database technology to that list).

In our forthcoming two-part spotlight on this space I’ll articulate in more detail our view on the differentiation of the various NoSQL databases and other big data technologies and their potential enterprise applicability. The first part, on NoSQL and operational databases, is here.

I recently blogged about the rise of NoSQL in the cloud and the threat to the SQL world, with predictions on how it will play out. http://scaledb.blogspot.com/2010/02/will-nosql-movement-unseat-database.html

[…] of the essential problems with the covering the NoSQL movement is that it describes not what the associated databases are, but what they are […]
