In Delta Live Tables (DLT):
You can now choose Performance Mode when scheduling a Triggered pipeline.
Two options:
Performance optimized (uses more aggressive scaling, higher resource burst)
Standard performance (normal serverless behavior)
BUT 👉 Performance mode setting only appears when you edit the pipeline schedule, not at cluster settings.

How To Select / Change Performance Mode for a DLT Pipeline
Step-by-Step (Azure Databricks):
1. Go to Workflows → Delta Live Tables Pipelines.
2. Select your existing pipeline or Create a New Pipeline.
3. In the Pipeline Settings Page, scroll to “Trigger settings” or find “Schedule Trigger”.
4. There you will find "Performance optimized" checkbox (✅😞
If you check it → Performance optimized mode (better scaling, faster startup, higher cost)
If you uncheck it → Standard mode (normal scaling)
5. Save the pipeline settings and Deploy.

Continuous Pipelines do not have Performance mode option yet.
Triggered Pipelines must use serverless for this checkbox to appear.
Sometimes in older UI versions (early 2024), the checkbox might not show. Make sure your workspace is updated.
If You Don’t See the Option
Make sure your workspace is updated to DBR 13.3 LTS or later.
