How BricksNotes reached every corner of the world
It started with a small frustration.
Most data engineering books go out of date before the ink dries. Databricks ships something new almost every month. Spark now releases every quarter. A book printed two years ago still teaches paths and patterns that no longer work.
So we asked a simple question. What if a book could keep learning, just like its readers?
That question became BricksNotes. Today, we want to share where that question has taken us, and say thank you.
BricksNotes has now welcomed more than 250,000 unique visitors.
When we wrote our first lesson, we hoped a few hundred engineers would find it useful. We never imagined a number like this. Every one of those visits is a person who chose to spend part of their day learning with us.
That means a lot.
Here is a simple look at how BricksNotes is growing. We share these numbers not to boast, but because data people like to see the data.
| Measure | Where We Are Today |
|---|---|
| Unique visitors | 250,000+ |
| Associate practice exams completed | 30,000+ |
| Professional practice exams completed | Thousands, and growing every week |
| Blog subscribers | Growing every single day |
| Videos in BricksNotes Watch | 73 and counting |
| Book updates | Every month, without a new edition |

Readers come from every corner of the world. Morning readers in India, Japan and Australia. Lunch-break readers in Europe and Africa. Late-night readers across the Americas. At almost any hour, someone somewhere is reading a BricksNotes lesson.
People come back. The most encouraging signal is not the first visit. It is the second, the fifth and the tenth. Readers return to finish chapters, retry practice exams and read the newest article.
Practice is where learning sticks. Practice exam completions keep climbing week after week. Readers are not just reading. They are testing themselves.
Our blog subscriber list is growing faster than ever.
Every new subscriber tells us something important. You trust us enough to let us into your inbox. We do not take that lightly.
So our promise stays the same. Simple English. No hype. Practical lessons you can try in Databricks Free Edition. And only when we have something useful to say.
This is the part we are most proud of.
The book is getting great adoption, and readers keep telling us the same thing. They can actually learn from it. Concepts make sense. Labs work. The ideas carry over to their real jobs.
The reason is simple. BricksNotes is not a static book.
When Databricks renamed Delta Live Tables to Lakeflow Declarative Pipelines, our lessons changed. When Apache Spark 4.3 arrived, readers learned about it that same week. When Unity Catalog Volumes became the right way to store files, our examples moved there too.
A printed book asks you to wait for a second edition. A living book simply keeps up.
You buy it once. It stays current. That is the deal we wanted as learners, so it is the deal we offer.
Behind the numbers are people.
A software engineer who finally understood why Spark jobs shuffle. An analyst who passed the Associate exam and moved into a data engineering role. A team lead who fixed a slow nightly pipeline and cut the cluster bill. A student who learned everything on Free Edition, without spending a single dollar on cloud.
Each message like this reminds us why we started. Learning data engineering should feel calm, clear and possible for anyone.
We are not slowing down.
More chapters will keep getting fresh updates. More articles on Data + AI will keep arriving. BricksNotes Watch will keep growing as a calm place to learn without the noise. And the first lessons of the book will stay free for every curious engineer.
Our goal is bigger than a book. We want BricksNotes to be a place where you can learn, practice, share and grow with Data + AI.
To every reader, subscriber, learner and sharer. Thank you.
You found us, you stayed and you told your friends. That is how a small idea reached every corner of the world.
Keep learning. Keep building. Keep growing.
With love, Team BricksNotes
