Workload Fit App
Overview
Workload Fit is an observability application used to evaluate Databricks workloads for migration readiness from Job Compute to serverless mode
Purpose
Workload Fit analyzes execution characteristics for each workload and recommends whether migration is a good fit. The assessments help users make informed decisions about cost savings, efficiency, and scalability.
Key Capabilities
Lists top eligible and ineligible Databricks Jobs for migration.
Evaluates workloads to determine migration readiness.
Filtering options let users filter workloads by Compute Type, Signature, or Task Name.
The Insight Summary provides a concise explanation about each workload’s suitability for serverless migration.
The app shows Key Operators that affect migration readiness.
Workload Overview reveals untapped savings, migration suitability percentages, and job run details.
Installing and opening the app
Refer to Installing and accessing the apps.
Using the Workload Fit app
Compute type: Specify the environment type, such as Automated clusters (Job-Compute).
Signature: Choose the workload profile to assess.
Task name: Select the job or task to review.
