Cloning libraries when cloning clustersCurrently when we clone clusters, the externally added libraries aren't copied as part of cloning process.It's an expected behavior but a missing one. At times new developers end up spending lot of time in debug...
In databricks jobs, there's a field to add concurrent runs which can be set to 1000.If I've a cluster with 4 worker nodes and 8 cores each, then at max how many concurrent jobs I'll be able to execute?What will happen if I launch 100 instances of sam...
@Aman Sehgal​ On E2 workspace the limit is 1000 concurrent runs. If you trigger 100 runs​ at the same time, 100 clusters will be created and the runs will be executed. If you use the same cluster for 100 runs, then you might face a lot of failed jobs...
In the release notes of May 2022 it says that we are now able to investigate our SQL results in python in a python notebook. (See also documentation here: Use notebooks - Azure Databricks | Microsoft Docs ) So I created a simple query (select * from ...

Hi AllI am loading some data using auto loader but am having trouble with Schema evolution.A new column has been added to the data I am loading and I am getting the following error:StreamingQueryException: Encountered unknown field(s) during parsing:...
I agree that hints are the way to go if you have the schema available but the whole point of schema evolution is that you might not always know the schema in advance.I received a similar error with a similar streaming query configuration. The issue w...
Is there a way to create a generic user account and personal access token to connect to databricks. I have Azure build pipeline and VSCode test that is using my personal access token for running builds and tests.
You can create a service account (principle) for jobs, applications etc. Here's a link to the docs:https://docs.databricks.com/administration-guide/users-groups/service-principals.html
I am trying to set up audit log delivery in google cloud. I have followed this page https://docs.gcp.databricks.com/administration-guide/account-settings-gcp/log-delivery.html and have added log-delivery@databricks-prod-master.iam.gserviceaccount.co...
I would suggest, contacting your Databricks accounts representative for this. They would be able to check if something went wrong with your workspace subscription.
For instance, I'm ingesting webhook data into a delta table with autoloader and need to run a process for each new record as it arrives.
With autoloader, you can do something like changelog and record data about operations performed on each micro batch - like affected id, I/U/D, timestamp etc..Then you can make use of this changelog table, and run subsequent processes for each row aff...
I want to know whether which cloud is better to learn and which cloud services has more career opportunities.
As addition to @Kaniz Fatma​ great comparison article, cloud skills are generally transferable across other providers. It is the same concept just with different names (eg: EC2 / Azure VM / Google Compute Engine). Learning cloud in general is a good ...
In Databricks 10.1 it is possible to define in the "Spark Config" of the cluster something like:spark.fernet {{secrets/myscope/encryption-key}} . In my case my scopes are tied to Azure Key Vault.With that I can make a query as follows:%sql SELECT d...
This solution exposes the entire secret if I use commands like belowsql("""explain select upper("${spark.fernet.email}") as data """).display()Please dont use this

I have a table in databricks called owner_final_delta with a column called contacts that holds data with this structure:array<struct<address:struct<apartment:string,city:string,house:string,poBox:string,sources:array<string>,state:string,street:strin...
Have you tried to use the explode function for that column with the array?df.select(explode(df.emailId).alias("email")).show()----------Also, if you are a SQL lover, you can instead use the Databricks syntax for querying a JSON seen here.
In Databricks I have a existing delta table, In which i want to add one more column, as Id so that each row has unique id no and It is consecutive (how primary key is present in sql).So far I have tried converting delta table to pyspark dataframe and...
How about defining an identity column as below?GENERATED { ALWAYS | BY DEFAULT } AS IDENTITY [ ( [ START WITH start ] [ INCREMENT BY step ] ) ]https://docs.databricks.com/sql/language-manual/sql-ref-syntax-ddl-create-table-using.html#parameters
@Tomasz Bacewicz​ I've got another, related question for you about the job cluster that is spun up for DLT jobs. Adding the JSON strings for our required E2 tags worked like a charm, but now I need to attach an existing Instance Profile since I'm tr...
@Brad Sheridan​ To do that you have to add the aws_attributes tag within a cluster configuration and there you have the ability to add an instance_profile_arn like so:"clusters": [ { "label": "default", "aws_attributes": { ...
