At Blizzard Entertainment, our business intelligence team helps users make data-driven decisions. One of the most interesting kinds of analysis we do is to look at in-game mechanics and features. We can tease out subtle insights from the petabytes of data from the many disparate data sources we have and we can feed those insights back to the game develop teams to make every player’s experience epic.

This is no small task, however. Each of Blizzard’s games have features that the others do not; gameplay in the real-time strategy StarCraft, for example, is completely and fundamentally different from that of the action RPG Diablo. In this presentation, we will describe what our creative teams need in order to make the design decisions that drive our different titles and how those needs are unique to the game and more often than not, even unique to specific game mechanics or features. Data sets even within a single game can be very different; some are high-level business metrics while others are gameplay details that are kept at the finest possible granularity; some are important for a single patch cycle only while others are significant over the entire life of a game.

We will then talk about why classic data warehousing approaches do not meet our needs. We can’t tolerate the loss of agility and responsiveness that those approaches impose due to architectural rigidity and resource bottlenecks. We also need to handle massive amounts of real-time streaming game data without being bound by pre-defined aggregations.

Finally, we will describe how several Hadoop-based technologies have allowed us to deal with more data at a deeper level than ever before. Our horizontally scalable infrastructure allows data to land and be immediately available to our data analysts with little or no development time. Even better, we can keep the data around in full detail so that we can come back later to answer the questions our creative teams didn’t yet know they had.

The presentation will emphasize the critical role users’ needs play in the design, implementation, and adoption of Hadoop within a fast-moving, dynamic environment that supports three Triple A game titles and all supporting business units. Participants are expected to see firsthand how understanding users’ needs can lead to a well-scoped and ultimately successful architectural design. Examples will cover both workflow- and data-design; code samples will feature the use of the Hadoop Streaming API and Python. Examples will feature interesting data sets from Blizzard titles.
