@ChristianRRL regarding on why DLT doesn't allow you to use all-purpose clusters: 1. The DLT runtime is derived from the shared compute DBR, it's not the same runtime and has different features than the common all-purpose runtime. A DLT pipeline is n...

The title is self-explanatory, but I'm curious if anyone has any inclination as to when Materialized Views will enter General Availability? I'm surprised it's not already in GA considering (A) it's been a year or more since Databricks originally anno...

Ideally one would expect clusters used for DLT pipeline to terminate after the pipeline execution has finished. However, while running in `development` environment, you'll notice it doesn't terminate on its own, whereas in `production` it terminates ...

Resolved! DLT Notebook and Pipeline Separation vs Consolidation
Super basic question. For DLT pipelines I see there's an option to add multiple "Paths". Is it generally best practice to completely separate `bronze` from `silver` notebooks? Or is it more recommended to bundle both raw `bronze` and clean `silver` d...

Well, one thing they emphasize in the 'Adavanced Data Engineer' Training is that job-clusters will terminate within 5 minutes after a job is completed. So this could be in support of your theory to lower costs. I think job-cluster are actually design...
