As someone who worked around the classic Data Warehouses back in the day, before s3 took over and SQL Server and Oracle ruled the day … I love sitting on the sidelines watching new … yet old battle-lines being re-drawn. I could probably scroll back in StackOverflow 12 years and find the same arguments and questions. In one sense Databricks and Snowflake are totally different tools … but are they? Distributed big data processing, apply transforms to data, enable Data Lake / Data Warehouse / Analytics at scale. There is a lot of bleed over between the two, it really comes down to what path you would like to take to get to the same goal.

One of the reoccurring complaints you always see being parroted by the smarter-then-anyone-else-on-the-internet Reddit lurkers is the slowness of Python. I mean I understand the complaint …. but I don’t understand the complaint. Python is what is is, and usually is the best at what it is, hence its ubiquitous nature. I’ve been dabbling with Scala for awhile, much to my chagrin, and have been wondering about its approach to concurrency for awhile now. I’ve used MultiProcessing and MultiThreading in Python to super charge a lot of tasks over the years, I want to see how easy or complex this would be in Scala, although I don’t think easy and Scala belong in the same sentence.

The two coolest kids in class … I mean seriously … every other post in Data Engineering world these days is about Apache Airflow or DataBricks. It’s hard to kick against the goad. Just jump on the band wagon before you get left in the dust. I’ve used both DataBricks and Apache Airflow, they both are pretty important and integral tools for data engineers these days. Apache Airflow makes overall complex pipeline dependencies, orchestration, and management intuitive and easy. DataBricks has delivered with AWS and EMR could not, easy to use Spark and DeltaLake functionality without the management and config nightmares of running Spark yourself.

Recently I worked on an Airflow and DataBricks/DeltaLake integration, time to talk what it looks like and options when doing this type integration.

Apache Druid, kinda like that second cousin you know about … but don’t really know. When you see them for the first time in 10 years you kinda look at them out of the corner of your eye. That’s how I feel about Apache Druid, I’ve always known it has been there, lurking around in the shadows, but it rarely pokes it head out and I have no idea what, why, how it is used. Time to change that, for the better or worse. Let’s take 10,000 foot survey of Druid.

When I used to think of lambda functions on AWS my eyes would glaze over, I would roll my eyes and say, “I work with big data, what in the world can a silly little AWS lambda function offer me?” I’ve had to eat my own words, those little suckers come in handy in my day to day engineering work. I want to talk about how every data engineer working with AWS can take advantage of lambda’s and add them to their data pipeline tool belt.
