Data Lake Storage Gen 2 is the best storage solution for big data analytics in Azure. With its Hadoop compatible access, it is a perfect fit for existing platforms like Databricks, Cloudera, Hortonworks, Hadoop, HDInsight and many more. Take advantage of both blob storage and data lake in one service!
In this episode I give you introduction to what Azure Data Lake Storage is, how it works and how can you leverage it in your big data workloads. I will also explain the differences between Blob and ADLS.
In a short demo I will show you
- What is Data Lake Storage and how it works and why is it called Gen2?
- What does it mean being designed for big data analytical workloads?
- How does multi-protocol access work?
- What are key differences between ADLS and Blob Storage?
- Quick demo of creating ADLS in portal
- Quick demo of connecting from Power BI and using multi-protocol access
- How to use storage explorer with ADLS
- How do Access Control Lists work and how to manage them
- Demo with Databricks and ADLS
Sample code from demo: github.com/MarczakIO/azure4ev...

Great video as per usual, your channel is my go-to for preparing for Azure Certification Exams! I do have a question regarding the ADLS Gen 2 hierarchy, as one of my friends is preparing for the DP-900 exam (regarding a practice question). The question asks you to match 2 of the following 3 terms ([Azure Storage Account], [File share], [Container]) in the following hierarchy (only one answer is allowed): Azure Resource Group - [TERM 1] - [TERM 2] - Folders - Files The suggested correct answer is: Azure Resource Group - [Azure Storage Account] - [File Share] - Folders - Files But I don't see any reason why the following answer would not also be correct (besides maybe because containers being called file systems in ADLS Gen 2?): Azure Resource Group - [Azure Storage Account] - [Container] - Folders - Files What is your take on this? Thanks for taking your time!

For Databricks mounting: Please note that Azure version as of today will copy the secret ID and not the password itself if you hit copy at the end of the line just like Adam does. Copying the secret password seems only possible immediately after the creation of the secret by the copy button that appears right after the password. Took me some time to figure this out..

Great video. One query. When you wrote back to the lake at the end of the demo, it was in partitions. How can we write back in a single file without partitions?
@AdamMarczakYT
@AdamMarczakYT 4 жыл бұрын
Good question! Since databricks is based on Spark and Spark is using Hadoop file system, it is normal behavior for files to be split into partitions. You can force single partition by using repartition or coalesce function with parameter of value '1'. If you wan't to skip entire folder with all hadoop parts then you can google for some scala/python scripts to do it. In general paritioning is good practice so merging is not recommended for bigger files as they will need to be loaded into memory which will cause issues with bigger data sets. Most other technologies like SQL DW (synapse), data factory are able to read from partitioned data sets just fine.
@sekhar8994
@sekhar8994 4 жыл бұрын
Adding to Adam's , You can write it into a single partition using coalesce/repartition and and then using os.path, delete the files that doesn't have a pattern *.csv/parquet and rename the file .

It looks like we don't necessarily need to use databricks, because ADF now support "Data Flows," which are a kind of no-code data transformation process. What are your thoughts on that? Is ADF a good substitution for Databricks (its actually using Databricks under the hood) for more advanced data transformation jobs?
@AdamMarczakYT
@AdamMarczakYT 4 жыл бұрын
hey Shawn, very good question. Since Microsoft removed Data Flow step which allowed you to input your own script blocks I'd say for advanced scenarios I would use databricks since I would want to have full control. Microsoft also removed ability to provide your own link service for dataflow which in return also means if you want to connect to data sources within your private networks then public integration runtimes will not be able to connect (it can however connect to firewall vnet protected resources using managed identity), nor will you be able to add custom libraries to your dataflow (again, you don't own cluster so you can't control this) hence again narrowing down some scenarios. Net net, my opinion is that general directory of Data Flow is for simple cloud transformation scenarios at this point in time.

When creating containers, how do I know exactly how many containers I should make? For example, if I'm creating 5 apps that are completely independent of each other and the apps save pictures that the users take to the storage account, should I have 5 containers (1 for each app)? Or 1 container to support all apps?

Hey Justin. There aren’t any specific limits scoped around containers so this is a design decision. There aren’t any specific guidelines so you should match what feels right for your organization and use case. But there are storage account level limits so those could be a deciding factor between one and many storage accounts, check those out in here docs.microsoft.com/en-us/azure/azure-resource-manager/management/azure-subscription-service-limits?WT.mc_id=AZ-MVP-5003556

Hey Adam that's a great demo. I want to know how you can programmatically put files in a folder based on the date of the file if I have year-->month-->day subdirectory structure, and then use a search pattern to only choose files of a particular month of year during processing of data within the data lake. Any ideas on how?

With databricks you can simply run something like val year = 2019 val month = 12 df.save.json(s"/mnt/data/$year/$month/myfile.json") and to get the files val files = dbutils.fs.ls(s"/mnt/data/$year/$month") note I wrote this on my phone so there might be typos, but you get general principle

When you say date of the file , do you mean ,last modified date of file or a date column in file ? if its last modified date , You can use input_filename() function to get the last modified date of file in a new column of dataframe and then accordingly you can get year, month & day as new columns and finally when you write back , just use parttitionBy() with year , month & day.

Very good introduction video, thank you. A quick question, why using AccessKey to mount Azure Blob Storage, using Service Principle to mount Data Lake? How do I use AccessKey to mount Data Lake?
@AdamMarczakYT
@AdamMarczakYT 4 жыл бұрын
Good question! There is pretty much no difference, I just wanted to show both approaches, service principal is recommended but access key will work too. Check out how to use access key for data lake in the docs: docs.databricks.com/data/data-sources/azure/azure-datalake-gen2.html

@@AdamMarczakYT Thank you. Another favor, will you be able to give a quick demo about Databricks? My impression about Databricks is all about in memory processing, good candidate for data streaming. Do you have a demo about from EventHub or ServiceBus to Databricks?

A quick correction, you should use select.write.csv(...) at 23:20, otherwise you would write all columns from original csv to the new csv file.
