Dear all. If you are playing around using "Azure Free" subscription you will encounter error that only 4 cores are allowed in your subscription. There is currently a new Cluster Mode called "Single Node" instead of "Standard" try this one, it should be good :)
Hello, is Azure Databricks a relational Database? Does Azure Databricks supports incremental refresh in power bi? Does azure Databricks supports query folding?
If there are Microsoft documents which answers these queries woukd of great help.
Anyone please help.
great help Adam! :))
This guy deserves way more subscribers
Thanks 🤩
@@AdamMarczakYT Totally agree!!! I love every single video!! Appreciate your effort :)
Yeah . Best videos on azure .
This guy deserve a huge applause. This piece of course helped me in understanding data bricks in way more clear.
Fantastic presentation! One of the best (if not the best) Azure series. Great job Adam.
Thank you for both creating this video and taking the time in putting it together. Much appreciated.
Thanks Christian :)
I just love the way Adam simplifies the concept, architecture, and real-world use cases of any Azure service. Thanks for another very informative video, really Great work, Adam.

I just subscribed to your channel, Adam. These videos are excellent and informative for all IT Professionals alike or anyone wanting to learn something IT.
This is a masterpiece, Adam! Totally understood the concept.
Adam, I found your Azure4Everyone videos yesterday. I am visual learner than reading, your videos made sense and easy to learn. Thank you for taking time to make all the videos.
Awesome, thank you!
Proper explanation, all things covered, and good way of teaching. Loved it.
Glad you liked it!
Adam, You made the jargon simplified, Thanks a lot! Will always prefer to watch and learn Azure from your quick simplified videos.
My pleasure!
Outstanding video Adam. Truly. Thank you for this. I found Microsoft's docs tough to navigate and I was concerned about spending too much $$ money on resources trying to learn. But your video addressed all that. I will be looking at more of your content for sure.
Awesome! Thanks John :)
Agree with Praveen - This guy deserves way more subscribers, extremely competent and clear presentation
Adam - For a person who has just started with Azure and its components, your videos are highly recommended. Keep doing the great work. Really liked your tutorials
Much appreciated! Will do!
Hi Adam, For a person who wants to just start with big data, Azure cloud, Data bricks and its components could you guide the sequence of your videos to follow. Sincere thanks in advance.
I´ve never learn about Azure like this before. Clean explanations about concepts and pretty cool hands on.
Glad you enjoyed it! Cheers! :)
Świetny tutorial. Pomógł mi w pracy. Dzięki
Your tutorials are class apart - very very good. Thank you so much.
Thank you so much Adam!....for taking the initiative and creating a great video.
Awesome, thanks!
Thanks, Adam, your instructions are very clear and easy to follow 👍
Great to hear!
Faced some minor issues in between like start time in sas generations, sas authorizations, timezones and regions etc., so deleted RG and restarted again from ground 0, finally works well! Thanks Adam for teaching even some complex things in simple ways! your passion helps us to learn new things!
Nice! Staying persistent is the best way to learn. Sometimes smallest mistakes are hardest to catch. It's easier to start over.
Great demo. The best summary of Data Bricks that I've seen
Thank you so much :)
Excellent Demo, simple and effective teaching methods. Thank you!
Glad you enjoyed it!
So very well explained! Thanks you for the great tutorial!
Please don't ever stop making tutorials on Azure cloud computing. Your explanation is mint. Can you please do one tutorial on how to automate ETL using Azure Logic Apps and ADF? Thank you so much. :)
Thanks! I won't stop, at least no plans to do so for now :). I;m not sure if I will do full logic apps + ADF + databricks tutorials since I want my videos to be a building blocks and let people put them together. But maybe, I'll think about it :) Thanks for watching!
helped me a lot to understand what databricks is for - thank you! Will have a look on your other videos for sure
Awesome, thank you!
Perfect - I was looking for an intro into Databricks and Data Factories - Thank you!

Hi Adam, Amazing video... is there any possibility to compare file snapshot using different time stamps like compare today's data vs yesterday's data in data bricks? if possible can you please help me the details that how we exactly compared? THANKS.
Great work Adam!
Thank you very much. I really enjoy your videos.
Glad you like them!
Thank you! Excellent tut
:)
Thank you very much.. your video helped me lot to understand the concepts:)
Glad to hear that!
Great video! Thank you Adam. I have one question, do you have any hint on how to deal with Blob when it is in VNET ?
There is an option to deploy Databricks to your specified VNet and then add that vnet in the firewall. Thanks!
Really really didactical, thanks for sharing!
Glad it helped!
Thank you, so good explanation!
Good to have a video that is technical and hands on

nice video and great introduction to Azure Databricks :)
Thanks! 😀
Great job thank you Adam
Even there are so many good comments here, I still want to say thank you, indeed very good.
I appreciate your comments, thanks for stopping by!
Thank you, it's very useful!
Awesome course! Ran into a few snags with the getting everything to work because the current version of Azure Databricks don't show what we see in the video. I can download the query results but I don't see anywhere, where you would create a visualization using pychart. A little frustrating but that is technology, the video is 2 years old and they have already made so many changes.
Great work Adam!! I have a question, when I am trying to create Data lake Gen2 storage account, Its not giving option of File system in container , even if I specify advanced option ( Hierarchy Name space) . Doesn't it work for some regions like South India, what location to be specify . Please help me !! Thank You!!
In blob storage container is equivalent of file system for data lake gen 2. They are the same thing. Check out my video on data lake gen 2 if you wanna learn more details. ua-cam.com/video/2uSkjBEwwq0/v-deo.html Thanks for watching.
Thanks Adam for this. Are there scenarios where you can't do something(read,write,connect, transform) in %sql mode v/s in python or scala?If so is %sql mode just a subset of what can be done in Python?
%sql is just subset directed at data transformations, I think the idea behind this was to allows people (analysts, data engineers, etc.) who are familiar with SQL languages to easily move to Spark technologies. It's not intended to be replacement of Python/Scala, just complement them with easy to read and write data transformations. Thanks for watching and commenting!
nice man.. keep up the good work.
Great Video Adam :)
I'm trying to perform data manipulation operations on datasets that range from 7 TB to 110 TB, most of the elementary operations like data.count(), distinct count etc. results in query timeout/failure. But same operations work just fine in datasets that weigh-in around 500 GB.
Is ADLA a more suitable option for my purpose than Databricks? I'm trying to switch from Cosmos which has been been able to handle the huge datasets without any hassel.
Personally I'm not sure how much I would invest in ADLA since the technology is not actively developed by Microsoft anymore. Probably would consider databricks delta tables or SQL DW (synapse) database. Databases are good at 'counts', 'sums', etc. because they have those calculated and cached upon insertion, so the queries are very fast.
Hi Nagappan VR! Is your cluster or are your VMs large enough ( memory and CPU) 110 TB is still relatively small for real big data workloads....
@@funwithazure1861 You are right, the cluster configuration was not scaled up enough to handle the workload.
Hi Adam, great video :). You presented a slide where Azure Data Factory is shown along with Databricks and other components. My questions is, do you already have a video or a link where the choice between data factory and Databricks is discussed? For instance, the transformations you presented can also be done with a data factory low-code approach. I guess scalability and performance can be good reasons for Databricks but would be nice to have some guidelines where to choose or even combine them.
Thanks Paul. Great question, no video yet. Just a fun fact that data factory low code approach (data flows) still compiles into a databricks package and is deployed as if you wrote the code yourself. So performance and scalability wise they are likely the same. Primary difference is that low-code has limitations of what is available in the UI, as such I typically say for data & analytics projects go databricks because you are almost guaranteed to need complex transformations which can't be achieved using low-code. But if you got a simple project with some simple data transformations low-code is great. Of' course my words might change in future with the release of wrangling data flows or implementation of new and new features. So we will see :)
Cudowny tutorial, gdyby każdy wykonywał swoją robotę w ten sposób, mielibyśmy inteligentne buty od nike'a i latające samochody :)
Ha ha! dziękuje ;) fajnie ze sie podobalo.
Another great presentation
Thanks! Appreciated!
Excellent Adam.Thanks
My pleasure!
Great job Adam!
