Guest Post: Are You Pouring Pollution into the Data Lake?

by Merv Adrian  |  October 10, 2014  |  Comments Off

From my esteemed colleague Mark Beyer “Unstructured data” is a misnomer—everyone finally agrees on that much, at least. It is a term that is often applied to information assets that are not relational. Sometimes it is applied to machine data generated by operational technologies. Sometimes it is applied to content, like documents, or even less specific text […]

Hadoop Investments Continue: Teradata, HP Jockey For Position

by Merv Adrian  |  July 24, 2014  |  5 Comments

Interest from the leading players continues to drive investment in the Hadoop marketplace. This week Teradata made two acquisitions – Revelytix and Hadapt – that enrich its already sophisticated big data portfolio, while HP made a $50M investment in, and joined the board of, Hortonworks. These moves continue the ongoing effort by leading players. 4 of […]

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 […]

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 […]

That Exciting New Stuff? Yeah… Wait Till It Ships.

by Merv Adrian  |  July 13, 2013  |  3 Comments

A brief rant here: I am asked with great frequency how this RDBMS will hold off that big data play, how data warehouses will survive in a world where Hadoop exists, or whether Apple is done now that Android is doing well. There is a fundamental fallacy implicit in these questions. Comparing what someone new […]

Hadoop and DI – A Platform Is Not A Solution

by Merv Adrian  |  February 10, 2013  |  15 Comments

“Hadoop people” and “RDBMS people” – including some DBAs who have contacted me recently –  clearly have different ideas about what Data Integration is. And both may  differ from what Ted Friedman (twitter: @ted_friedman) and I (@merv) were talking about in our Gartner research note Hadoop Is Not a Data Integration Solution, although I think […]

Stack Up Hadoop to Find Its Place in Your Architecture

by Merv Adrian  |  January 30, 2013  |  8 Comments

2013 promises to be a banner year for Apache Hadoop, platform providers, related technologies – and analysts who try to sort it out. I’ve been wrestling with ways to make sense of it for Gartner clients bewildered by a new set of choices, and for them and myself, I’ve built a stack diagram that describes […]

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 […]
