MapReduce: All content tagged as MapReduce in NoSQL databases and polyglot persistence
A great matrix of the different analytics use cases across industries in Hortonworks’s post “Enterprise Hadoop and the Journey to a Data Lake“:
The data type column section covers multiple dimensions of data. And the authors took a conservative approach for the structured and unstructured categories (in the sense that they marked very few categories as unstructured).
A couple of interesting exercises that can be done using this matrix as an input:
figure out how adding data from different categories to a specific use case would benefit it. One obvious example is: how would Telecom companies benefit from adding to their infrastructure analysis social data?
Building on the above, decide what tools exist to help with this extra scenario.
can one use case from an industry be applied to a different industry to disrupt it?
What would be the quickest road to accomplish it?

Earlier today I’ve posted about Teradata’s take on the evolution of databases. As expected, everything is safe and under control. Now this report from Larry Dignan for ZDNet about Teradata Q4 earnings call presents Teradata’s perspective about Hadoop:
Teradata’s fourth quarter earnings were solid, but analysts peppered management with questions about Hadoop as data warehouse revenue worries persist.
Teradata CEO Mike Koehler and CFO Steve Scheppmann talked Hadoop throughout the company’s conference call. Was Hadoop taking Teradata’s business away? What’s the revenue hit? Can Teradata co-exist?
Once again everything is safe with a bright future. Until it isn’t anymore and Hadoop eats the enterprise data warehouse space. In Teradata’s defense, they’ve been one of the first companies that has looked seriously at Hadoop and came up with a coherent positioning.

For Cloudera, the first vendor to offer a Hadoop distribution, the answer is an unequivocal yes. Last November, Cloudera finally exposed its true sentiments by introducing the Enterprise Data Hub in which Hadoop replaces the data warehouse, among other things, as the center of an organization’s data management strategy. In contrast, Hortonworks takes a hybrid approach, partnering with leading commercial data management and analytics vendors to create a data environment that blends the best of Hadoop and commercial software. In short, Cloudera offers revolution, Hortonworks evolution.
You know what? Both are right. To replace existing enterprise data warehouse, the first step is in cohabiting with them.
