DATA WORLD: The Risks of Using Databricks for Data Warehousing

Tags

Get that Databricks Out of My Face!

You need not loathe Databricks outright. It is perfectly defensible if you do. This is particularly true when your principal objective is classical data warehousing. This includes structured BI reporting, dependable SQL analytics, and a governed single source of truth for business metrics. It also entails semantic clarity and predictable costs for read-heavy workloads.

There are solid, well-trodden reasons for that caveat. Many experienced data warehousing practitioners see Databricks as an awkward or even risky primary platform for traditional warehousing. This view is shared by some of the field’s foundational figures. The concern is not ideological. It is architectural. When used as a warehouse, Databricks often reproduces exactly the pathologies criticised in enterprise data programs. These include unnecessary complexity, misdirected effort, and the perennial executive question, “Which number should I trust?”

To begin at the beginning

To paraphrase the great Bob Hoffman. Just when you feared that Agile evangelists might produce even more nonsense, they surprise you. What do they do? Exceed expectations.

And how did they do that? Ladies and gentlemen, let me introduce you to Agile at Scale. It comes with all the miscellaneous, spiced-up, and vainglorious crap-on-the-side that accompanies it.

Scope

I’ll make this short, sweetish and to the point.

These are the arguments that CEOs need to know about Big Data.

It was written for CEOs and those who provide independent advice to CEOs.

If you are someone who wants to be prepared for CEOs who are armed with the realities of Big Data, then maybe this is for you too.

Point One: Big Data is bullshit

Carmarthen, Wales – 31st July 2017 

Many Brexiteers take a simplistic, restricted and shallow view of how the UK will leave the European Union.

It’s to be expected.

Some people are both wilfully ignorant and certain of their beliefs, even though their beliefs are no better than reactionary and rationalised prejudice, socialised absurdity and tidy-minded incongruence.

It’s to be expected. Continue reading

What to say?

I was reading an article. It was written by Jeff Wilts and recommended by Bill Inmon. I got to this statement: “Teradata is a full-featured enterprise data warehouse.”  For me, it went further downhill from there.

But this was the coup de grace: “Databricks is a unified data platform that can behave like a data warehouse.”

UNIVAC: Predicting Elections and Defining Computing History – 2026/02/06


Anecdotes about UNIVAC and the early days of computing

UNIVAC and the Eisenhower Prediction

One of the most famous anecdotes involving UNIVAC was its prediction of the outcome of the 1952 U.S. presidential election between Dwight D. Eisenhower and Adlai Stevenson. As the first computer used for commercial purposes, UNIVAC was tasked with predicting the election results. On live television, UNIVAC correctly predicted Eisenhower’s victory, despite widespread scepticism about the machine’s accuracy.

Many people come up to me in the street and ask me what big-data is all about. I have experienced this numerous times before. I am sure it might just happen to you as well. I know sort of thing, I read the big-data tea leaves. Nothing gets past me.

MASTERCLASS: What Are Surrogate Keys? – 2026/02/04

Tags

, , ,


Introduction

In data modelling and database design, keys play a fundamental role in uniquely identifying records and defining relationships between tables. One of the most widely used types of keys, especially in analytical systems and data warehouses, is the surrogate key.

A surrogate key is an artificial, system-generated identifier assigned to a record in a table. It is typically used as the primary key. It has no business meaning or semantic relationship to the real-world entity it represents. Common implementations include auto-incrementing integers or globally unique identifiers (GUIDs).

Surrogate keys exist purely to serve the needs of the database system: performance, stability, and simplicity.

The End of the Fortress: Why the Future of Data is “Liquid”

By Martyn Rhisiart Jones | Madrid, 3rd February 2026

In a landmark session at the Welsh Academy, Sir Afilonius Rex sat down with Martyn Rhisiart Jones. They aimed to dismantle our outdated obsession with “data management.” The verdict? The era of the digital fortress is dead. In its place, a new paradigm of Cognitive Liquidity and Data Autonomy is emerging, redefining how we integrate global knowledge.
