Even though you may be thinking now about Data+AI Summit 2024, I still owe you my retrospective for the 2023 edition. Let's start with the first part covering stream processing talks!
In our social media and marketing-driven era, it's quite hard to get things right. For me there is one common misconception brought by the Modern Data Stack idea that everything should be now ELT. In fact no, it shouldn't but only can.
That's the conference I've heard only recently about. What a huge mistake! Despite the lack of "data" word in the name, it covers many interesting data topics and before I share with you my notes from this year's Data+AI Summit, let me do the same for Berlin Buzzwords!
Welcome to the 3rd part of the series with great streaming and project organization blog posts summaries!
After a 2-years break, I had a chance to speak again, this time at the Big Data Warsaw 2023. Even though I couldn't be in Warsaw that day, I enjoyed the experience and also watched other sessions available through the conference platform.
Welcome to the 2nd part of the series with great streaming and project organization blog posts summaries!
Having a scalable architecture is the nowadays must but sometimes it may not be enough to provide consistent performance. Sometimes the business requirements, such as consistent delivery time or ordered delivery, can add some additional overhead. Consequently, scalability may not suffice. Fortunately, there are other mechanisms like backpressure that can be helpful.
Hi and welcome to the new series. This time I won't blog about my discoveries. Instead, I'm going to see other blog posts from the data engineering space and share some key takeaways with you. I don't know how regular it will be yet but hopefully will be able to share some of the notes every month.
Welcome to the 2nd blog post dedicated to Apache Airflow 2 features. This time it'll be more about custom code you can add to the most recent version.
Apache Airflow 2 introduced a lot of new features. The most visible one is probably a reworked UI but there is more! In this and the next blog post I'll show some of the interesting new Apache Airflow features.
Modern data space is an exciting place with a lot of innovation these last years. The single drawback of that movement are all the new buzz words and the time required to understand and classify them into something we could use in the organization or not. Recently I see more and more "data contracts" in social media. It's also a new term and I'd like to see if and how it revolutionizes the data space.
PySpark has been getting interesting improvements making it more Python and user-friendly in each release. However, it's not the single Python-based framework for distributed data processing and people talk more and more often about the alternatives like Dask or Ray. Since both are completely new for me, I'm going to use this blog post to shed some light on them, and why not plan a deeper exploration next year?
And it shouldn't be, right? After all, it's "just" about using a Unit Test framework and defining the test cases. Well, that's "just" a theory!
The "Data is the new Oil" is one of popular sentences describing the huge role of data in our world. And as other resources, data must be extracted too. To find these "Oil workers", organizations look for, among others, data engineers. The task is more or less easier and this difficulty depends on various factors. From my 6-years perspective, one of the key starting elements is the job announcement.
Yesterday I shared with you the human part of my Data+AI Summit. It's time now to give you my takeaways from the technical talks.
There will be many "first times" in our lives. For me, the Data+AI Summit 2022 was the first time I've visited the USA, put the 3D dimensions to the pictures of my virtual friends and felt a huge community support in a very troubled moment. Besides, I also enjoyed the talks and walking, even though the latter one wasn't so good for my skin ;)
More and more often in my daily contact with the data world I hear this word "modern". And I couldn't get it. I was doing cloud data engineering with Apache Spark/Apache Beam, so it wasn't modern at all? No idea while I'm writing this introduction. But I hope to know more about this term by the end of the article!
Recently you've discovered the building blocks of a feature store. This time I would like to demonstrate a feature store in action. I've chosen Feast as a playground use case because it's Open Source, has good working examples, and implements an Apache Spark ingestion job!
Feature stores are a more and more common topic in the data landscape and they have been in my backlog for several months already. Finally, I ended up writing the blog post and I really appreciated the learning experience! Even though it's a blog post from a data engineer perspective, so maybe without a deep data science deep dive.
In my previous post I shared with you an approach called crypto-shredding that eventually can end up as a solution for the "right to be forgotten" point of GDPR. One of its drawbacks was performance degradation due to the need to fetch and decrypt every sensible value. To overcome it, I thought first about a cache but ended up by understanding that it's not the cache but something else! And I will explain this in the blog post.
