Hi All,my question is in regard to how data in salesforce data cloud gets unified based on client profiles. Can similar action be done on data in databricks. i believe unity catalog just provides unified layer for security and governance. is there a ...
You want to identify actual persons based on one or more profiles (based on e-mail address etc). That is something that is not available out-of-the box in Databricks. The 'unified' in Databricks means you have a single platform for several data top...
Why does something like df.style.hide_index() turn out so ugly in Databricks? That command should show the dataframe pretty like always, but simply with the index column concealed. Instead, here's an image of what happens instead (displayi...

Hi all,I hope you could help me to figure out what I am missing.I'm trying to do a simple thing. To read the data from the data ingestion zone (csv files saved to Azure Storage Account) using the Delta Live Tables pipeline and share the resulting tab...
I'm curious if Databricks plans to address this. We use delta live streaming tables extensively and also planned on using delta sharing to get our data from our production unity catalog (different region). Duplicating the data as a workaround is no...

I am trying to follow along with a training course, but I am consistently running into an error loading a CSV with Spark from DBFS. Specifically, I keep getting an "Invalid format detected error". Has anyone else encountered this and found a soluti...
Well your error message is telling you that Spark is encountering a Delta table conflict while trying to read a CSV file. The file path dbfs:/mnt/dbacademy... points to a CSV file. This is where the fun begins. Spark detects a Delta transaction log d...
Hi,This is my sample JSON data which is generated from api response and it is all coming in a single row. I want to split this in multiple rows and store it in a dataframe.[{"transaction_id":"F6001EC5-528196D1","corrects_transaction_id":null,"transac...
Yes indeed, it was datatype issue. After changing it to Longtype in the schema definition, it is working now. Thanks once again for all your inputs and time. Much appreciated !!!
When I use show tblproperties on a view/table to see the metadata, it will redact any value which has "userid" anywhere put in to it.And it is not just through the visual interface, when I query it through python directly, it contains the redacted va...

Hello, @sirishavemula20 It's a general practice for a proctor to ask the test taker to pan the room(as part of security measures) and its the responsibility of the test taker to make sure the surroundings are clear of any other objects whilst attempt...
Hello,I've been trying to serve registered MLflow models at GPU Model Serving Endpoint, which works except for the models using bitsandbytes library. The library is used to quantise the LLM models into 4-bit/ 8-bit (e.g. Mistral-7B), however, it runs...
