Good afternoon,I'm currently going through Module 4 of the Data Engineering Associate pathway, specifically lesson 4.1 - DLT UI Walkthrough. We are instructed to specify the Cluster Policy as 'DBAcademy DLT' when configuring the pipeline. However, th...
Hi!I use Databricks in Azure and I find it inconvenient not knowing the last modified user and modified time. How can I trace the history of modified time and user details? Would it be possible to deploy the workflows into higher environments?Thanks!
Sorry! I added another issue at the end without mentioning it was a new issue I encountered. I had challenges in changing the owner of a workflow when I created a workflow. I ended up seeking help from another user with admin privileges to change the...

We have a spark streaming job that consumes data from a Kafka topic and writes out to delta tables in Unity Catalog.Looking to refactor it to use Delta Live Tables, but it appears that it is not possible at present to have a DLT Pipeline that can acc...
Hi Everyone!I am new to Databricks, and had chosen to use the Cloudformation template to create my AWS Workspace. I regretfully must admit I felt creative in the process and varied the suggested stackname and that must have created errors which ended...
You can enable "decommissioning" in spark, which causes it to remove work from a worker when it gets a notification from the cloud that the instance goes away (e.g. SPOT instances). This is dissabled by default, but it seems like such a no-brainer to...
Hi all,We are having issues with the datetype data type in spark when ingesting files.Effectively the source data has 6 microseconds worth of precision but the most we can extract from the datatype is three. For example 12:03:23.123, but what is requ...
