Hi Databricks Gurus !I am trying to run a very simple snippet :data_emp=[["1","sarvan","1"],["2","John","2"],["3","Jose","1"]]emp_columns=["EmpId","Name","Dept"]df=spark.createDataFrame(data=data_emp, schema=emp_columns)df.show() --------Based on a g...
In a DLT pipeline I have a bronze table that ingest files using Autoloader, and a derived silver table that, for this example, just stores the number of rows for each file ingested into bronze. The basic code example: import dlt from pyspark.sql impo...
Gotcha. Thanks for the reply.We already have a medallion architecture going in production for a while, based on DLT pipelines having most bronze/silver tables, with some separate jobs for silver tables that are more complex to materialize. It works, ...
I have created an init script stored in a Volume which I want to execute on a cluster with runtime 16.4 LTS. The cluster has policy = Unrestricted and Access mode = Standard. I have additionally added the init script to the allowlist. This should be ...
Hi @jimoskar ,Since you're using standard access mode you need to add init script to allowlist. Did you add your init script to allowlist? If not, do the following:In your Databricks workspace, click Catalog.Click the gear icon .Click the metastore ...
Let’s say we have big data application where data loss is not an option.Having GZRS (geo-zone-redundant storage) redundancy we would achieve zero data loss if primary region is alive – writer is waiting for acks from two or more Azure availability zo...
In Azure and Databricks environments, ensuring zero data loss during a primary-to-secondary failover—especially for Delta Lake/streaming workloads—is extremely challenging due to asynchronous replication, potential ordering issues, and inconsistent s...
Is there is any way/plans of Databricks use Delta sharing to provide data access to Celonis?
Hi @cbhoga ,Delta Sharing is an open protocol for secure data sharing. Databricks already supports it natively, so you can publish data using Delta Sharing. However, whether Celonis can directly consume that shared data depends on whether Celonis sup...
Hi there, I would appreciate some help to compare the runtime performance of two approaches to performing ELT in Databricks: spark.read vs. Autoloader. We already have a process in place to extract highly nested json data into a landing path, and fro...
Hi @ChristianRRL ,For that kind of ingestion scenario autoloader is a winner . It will scale much better than batch approach - especially if we are talking about large number of files.If you configure autoloader with file notification mode it can sca...
Hi there, I would appreciate some input on AutoLoader best practice. I've read that some people recommend that the latest data should be loaded in its rawest form into a raw delta table (i.e. highly nested json-like schema) and from that data the app...
I think the key thing with holding the raw data in a table, and not transforming that table, is that you have more flexibility at your disposal. There's a great resource available via Databricks Docs for best practices in the Lakehouse. I'd highly re...
Bit of a silly question, but wondering if someone can help me better understand what is `read_files`?read_files table-valued function | Databricks on AWSThere's at least 3 ways to pull raw json data into a spark dataframe:df = spark.read...df = spark...
Also, @ChristianRRL , with a slight adjustment to the syntax, it does indeed behave like Autoloaderhttps://docs.databricks.com/aws/en/ingestion/cloud-object-storage/auto-loader/patterns?language=SQL I'd also advise looking at the different options th...
Hi, originally I accidentally made a customer academy account with my company that is a databricks partner. Then I made an account using my personal email and listed my company email as the partner email for the partner academy account. that account ...

What I'm trying to achieve: ingest files into bronze tables with Autoloader, then produce Kafka messages for each file ingested using a DLT sink.The issue: latency between file ingested and message produced get exponentially higher the more tables ar...
Hi, I think it is a delay of the autoloader as it doesn't know about the ingested files. It is nothing in common with the state, as it is just an autoloader and it keeps a list of processed files. Autloader scans the directory every minute, usually a...
If you were creating Unity Catalogs again, what would you do differently based on your past experience?
From my experiance:- don't create separate catalogs for every project. Try to think about your desing before implementation- try to come up with consistent naming convention to avoid cognitive overhead- principle of least privilege - grant users and ...
In the second onboarding video, the Quickstart Notebook is shown. I found that notebook here:https://www.databricks.com/notebooks/gcp-qs-notebook.htmlI wanted to import it to my workspace in Azure Databricks account, to play with it. However, selecti...
Hi,I am having a hard time configuring my Databricks workspace when working in VSCode via WSL. When following the steps to setup Databricks authentication I am receiving the following error on the Step 5 of "Step 4: Set up Databricks authentication"....
What worked for me was NOT opening the browser using the pop-up (which generated the 3-legged-OAuth flow error), but clicking on the link provided by the CLI (or copy paste the link on the browser)
Hi all,I am very new to databricks and to this community. I recently signed up for the data analyst learning plan and the data engineering one.The learning platform page seems like confusing maze to navigate! In the course material for the data analy...
Thanks for your reply. I believe I have access to the partner academy through my company as I am able to access the partner academy through this link I can access the courses and various learning plans. However, I am not able to see the actual lab fi...
