The reason you are only seeing SQL Warehouses when clicking Compute is likely because the workspace admin has locked down interactive cluster creation. Check if you have the cluster creation entitlement. Your workspace admin can grant you the correct...

You can use the Google Drive Managed connector that does most of it primarily built for syncing structured data directly to Delta Tables or the Standard connector that allows you to use Databricks (SQL, Auto Loader, pipelines) directly against a Goog...

@prakharsachan What you're seeing is designed behavior, not a bug.When you run `bundle deploy`, the CLI does not upload everything in your bundle folder. It builds the upload list by walking the directory and skipping anything your .gitignore matches...

@yanchr To the checkpoint part of your question first. There is no supported way to carry DLT checkpoint state over to a different pipeline, and that includes a pipeline in another workspace. This is true even on hive metastore, where the pipeline's ...

This is a known class of issue, not user error. Delta Lake stores min/max/null-count statistics in JSON using dot notation to represent nested struct paths (e.g. address.city means the city field inside an address struct). When a flat column...

Hi there, from your note and comments, I couldn't gather if you have tried standard compute. Did you experience the same issues with standard compute? With serverless, you might experience some snags since the infrastructure is owned by Databricks an...

@animeshjain What's happening is that two different components are checking your config, and they are at different versions.databricks bundle schema is generated from the CLI binary itself, and your CLI is latest enough enough to know about lifecycle...

It doesn't sound like the === operator itself is the issue, since it should compile into a normal Catalyst expression rather than a SQL function call. The fact that Spark is trying to resolve = as a routine makes me suspect a catalog or analyzer beha...
