Indexing Hadoop: If it’s so simple, how come not everyone’s doing it?
Is Hadoop really the best thing since sliced bread? You’d probably get this idea, if you have been talking to any of the (proliferating) Hadoop advocates / vendors. Hadoop and its expanding ecosystem are being touted as the ideal solution to any organization’s data management needs – and admittedly, for good reason. Hadoop offers a […]Read More →
Data modeling for APIs. Part 3: SOAP and XML
In the third part of this series of posts we take a look at some of the details of data modeling for APIs using an XML – SOAP approach. SOAP has been around for a while now, as it was designed as an object-access protocol in 1998 by Dave Winer, Don Box, Bob Atkinson, and […]Read More →
Twitter doesn’t like me, but it’s nothing personal: stock plunges, engagement, and walled gardens

You probably know David Linthicum and Janakiram MSV as renowned cloud experts, and you may know myself from work we’ve done with Gigaom and Interworks as an up and coming vendor. Given that, you are most likely to be interested in our webinar […]Read More →
Data Modeling for APIs. Part 2: REST and JSON
In the second part of this series of posts we start looking into the implications of the choice between a SOAP and a REST approach to implementing APIs from a data modeling perspective. For most people a SOAP API is associated with an XML data model, while a REST API is associated with a JSON […]Read More →
A small step for Impala, a big step for SQL-on-Hadoop. More to come, hopefully.
Recently Cloudera published the results of a benchmark performed internally, comparing its own SQL-on-Hadoop implementation (Impala) against a carefully selected competition composed of Hive and an undisclosed RDBMS and showing that Impala outperforms both. As Gigaom’s Derrick Harris was quick to point out, beating Hive is not something to write home about as Hive is […]Read More →
Data Modeling for APIs. Part 1: setting the stage
Lately we’ve been engaged in the design of a data model for a project aiming to deliver an API for analytics in the domain of energy. As there is an ongoing debate in the consortium wrt to the type of API that will be implemented (RESTful vs Web Services), we have been asked to provide […]Read More →
