As we enter December and 2022 draws to a close, so does a significant chapter in my working career—later this month I’ll be leaving Confluent and onto pastures new.

It’s nearly six years since I wrote a 'moving on' blog entry, and as well as sharing what I’ll be working on next (and why), I also want to reflect on how much I’ve benefited from my time at Confluent and particularly the people with whom I worked.

In my quest to bring myself up to date with where the data & analytics engineering world is at nowadays, I’m going to build on my exploration of the storage and access technologies and look at the tools we use for loading and transforming data.

I started my dbt journey by poking and pulling at the pre-built jaffle_shop demo running with DuckDB as its data store. Now I want to see if I can put it to use myself to wrangle the session feedback data that came in from Current 2022. I’ve analysed this already, but it struck me that a particular part of it would benefit from some tidying up - and be a good excuse to see what it’s like using dbt to do so.

I’ve been wanting to try out dbt for some time now, and a recent long-haul flight seemed like the obvious opportunity to do so. Except many of the tutorials with dbt that I found were based on using Cloud, and airplane WiFi is generally sucky or non-existant. Then I found the DuckDB-based demo of dbt, which seemed to fit the bill (🦆 geddit?!) perfectly, since DuckDB runs locally. In addition, DuckDB had appeared on my radar recently and I was keen to check it out.

This is one of those you had to be there moments. If you come into the world of data and analytics engineering today, ELT is just what it is and is pretty much universally understood. But if you’ve been around for …waves hands… longer than that, you might be confused by what people are calling ELT and ETL. Well, I was ✋.

At Current 22 a few of us will be going for an early run on Tuesday morning. Everyone is very welcome!

As I’ve been reading and exploring the current world of data engineering I’ve been adding links to my Raindrop.io collection, so check that out. In addition, below are some specific resources that I’d recommend.

In this article I look at where we store our analytical data, how we organise it, and how we enable access to it. I’m considering here potentially large volumes of data for access throughout an organisation. I’m not looking at data stores that are used for specific purposes (caches, low-latency analytics, graph etc).

The article is part of a series in which I explore the world of data engineering in 2022 and how it has changed from when I started my career in data warehousing 20+ years ago. Read the introduction for more context and background.

For the past 5.5 years I’ve been head-down in the exciting area of stream processing and events, and I realised recently that the world of data and analytics that I worked in up to 2017 which was changing significantly back then (Big Data, y’all!) has evolved and, dare I say it, matured somewhat - and I’ve not necessarily kept up with it. In this series of posts you can follow along as I start to reacquaint myself with where it’s got to these days.
