Which SQL on Hadoop? Poll Still Says “Whatever” But DBMS Providers Gain

by Merv Adrian  |  February 22, 2015  |  1 Comment

Since Nick Heudecker and I began our quarterly Hadoop webinars, we have asked our audiences what they expected to do about SQL several times, first in January 2014. With 164 respondents in that survey, 32% said “we’ll use what our existing BI tool provider gives us,” reflecting the fact that most adopters seem not to want […]

Prediction Is Hard – Especially About the Future

by Merv Adrian  |  December 30, 2014  |  5 Comments

OK, I admit it – I stole the title from a much smarter man. I thought that man was Yogi Berra, but maybe not – more about that at the end of this post. Every year, Gartner issues a series of Predicts documents. This year I had the pleasure of doing one for my team […]

DBMS Legacies are Very Sticky

by Merv Adrian  |  December 18, 2014  |  3 Comments

Donald Feinberg (@Brazingo) & Merv Adrian (@merv) Every so often, there’s a wave of interest in the “imminent retirement” of one or more legacy database management systems (DBMS). Usually, it’s because someone with very little knowledge of the actual use and distribution of the products becomes enthusiastic about someone’s sales pitch, or an anecdote or […]

Aspirational Marketing and Enterprise Data Hubs

by Merv Adrian  |  January 17, 2014  |  3 Comments

In the Hadoop community there is a great deal of talk of late about its positioning as an Enterprise Data Hub. My description of this is “aspirational marketing;” it addresses the ambition its advocates have for how Hadoop will be used, when it realizes the vision of capabilities currently in early development. There’s nothing wrong […]

AAA is Not Enough Security in the Big Data Era

by Merv Adrian  |  January 13, 2014  |  11 Comments

Talk to security folks, especially network ones, and AAA will likely come up. It stands for authentication, authorization and accounting (sometimes audit). There are even protocols such as Radius (Remote Authentication Dial In User Service, much evolved from its first uses) and Diameter, its significantly expanded (and punnily named) newer cousin, implemented in commercial and […]

BYOH – Hadoop’s a Platform. Get Used To It.

by Merv Adrian  |  October 9, 2013  |  9 Comments

When is a technology offering a platform? Arguably, when people build products assuming it will be there. Or extend their existing products to support it, or add versions designed to run on it. Hadoop is there. The age of Bring Your Own Hadoop (BYOH) is clearly upon us.  Specific support for components such as Pig […]

Hadoop Summit Recap Part Two – SELECT FROM hdfs WHERE bigdatavendor USING SQL

by Merv Adrian  |  July 15, 2013  |  10 Comments

Probably the most widespread, and commercially imminent, theme at the Summit was “SQL on Hadoop.” Since last year, many offerings have been touted, debated, and some have even shipped. In this post, I offer a brief look at where things stood at the Summit and how we got there. To net it out: offerings today […]

2013 Data Resolution: Avoid Architectural Cul-de-Sacs

by Merv Adrian  |  December 27, 2012  |  6 Comments

I had an inquiry today from a client using packaged software for a business system that is built on a proprietary, non-relational datastore (in this case an object-oriented DBMS.) They have an older version of the product – having “failed” with a recent upgrade attempt. The client contacted me to ask about ways to integrate this […]

Amazon Redshift Disrupts DW Economics – But Nothing Comes Without Costs

by Merv Adrian  |  December 8, 2012  |  7 Comments

At its first re:Invent conference in Late November, Amazon announced Redshift, a new managed service for data warehousing. Amazon also offered details and customer examples that made AWS’  steady inroads toward enterprise, mainstream application acceptance very visible. Redshift is made available via MPP nodes of 2TB (XL) or 16TB (8XL), running the Paraccel PADB high-performance columnar, compressed […]
