We've seen many things change in languages, architectures, platforms, and processes. But through all this time one thing has stayed constant—relational databases store the data.

There have been challengers, some of which have had success in some niches, but on the whole the data storage question for architects has been the question of which relational database to use.

There is a lot of value in the stability of this reign.

An organization's data lasts much longer than its programs at least that's what people tell us—we've seen plenty of very old programs out there. It's valuable to have a stable data storage that's well understood and accessible from many application programming platforms.

Now, however, there's a new challenger on the block under the confrontational tag of NoSQL. It's born out of a need to handle larger data volumes which forced a fundamental shift to building large hardware platforms through clusters of commodity servers.

This need has also raised long-running concerns about the difficulties of making application code play well with the relational data model.

The term "NoSQL" is very ill-defined. It's generally applied to a number of recent nonrelational databases such as Cassandra, Mongo, Neo4J, and Riak. They embrace schemaless data, run on clusters, and have the ability to trade off traditional consistency for other useful properties. Log In Sign Up.

NoSQL Distilled: A Brief Guide to the Emerging World of Polyglot Persistence

They embrace schemaless data, run on clusters, and have the ability to trade off traditional consistency for other useful properties. Advocates of NoSQL databases claim that they can build systems that are more performant, scale much better, and are easier to program with. Our view is that we are entering a world of Polyglot Persistence where enterprises, and even individual applications, use multiple technologies for data management.

As a result, architects will need to be familiar with these technologies and be able to evaluate which ones to use for differing needs.

This book seeks to give you enough information to answer the question of whether NoSQL databases are worth serious consideration for your future projects. Instead, what we are attempting here is to provide you with enough background on how NoSQL databases work, so that you can make those judgments yourself without having to trawl the whole web.

We see two primary reasons why people consider using a NoSQL database. A lot of application development effort is spent on mapping data between in-memory data structures and a relational database.

The primary reason is that a relational database is designed to run on a single machine, but it is usually more economic to run large data and computing loads on clusters of many smaller and cheaper machines. In the second part we concentrate more on implementing systems with NoSQL databases. Preface xv Chapter 1 begins by explaining why NoSQL has had such a rapid rise—the need to process larger data volumes led to a shift, in large systems, from scaling vertically to scaling horizontally on clusters.

This explains an important feature of the data model of many NoSQL databases—the explicit storage of a rich structure of closely related data that is accessed as a unit. In this book we call this kind of structure an aggregate.

Chapter 2 describes how aggregates manifest themselves in three of the main data models in NoSQL land: Aggregates provide a natural unit of interaction for many kinds of applications, which both improves running on a cluster and makes it easier to program the data access.

Having covered the data-modeling aspect of NoSQL, we move on to distribu- tion: Chapter 4 describes how databases distribute data to run on clusters. NoSQL databases provide a more varied range of consistency options than relational databases—which is a consequence of being friendly to clusters. While these chapters concentrate primarily on the principles of how data gets distributed and kept consistent, the next two chapters talk about a couple of important tools that make this work.

Chapter 6 describes version stamps, which are for keeping track of changes and detecting inconsistencies. We must stress that this is not a comprehensive study—there are too many out there to write about, let alone for us to try.With this growth in data came a growth in users—as the biggest websites grew to be vast estates regularly serving huge numbers of visitors.

Graph databases are motivated by a different frustration with relational databases and thus have an opposite model—small records with complex interconnections.

It certainly makes it much easier to work with Hadoop than the underlying Java libraries.

Pessimistic approaches often severely degrade the responsiveness of a system to the degree that it becomes unfit for its purpose.
