Legacy Compute Preview System Schema Deprecation

Transitioning to the new system.compute schema for enhanced data management.

GA Open docs ↗release note ↗
What it does

The legacy `compute_preview` system schema has been deprecated and will be removed from the `system` catalog, urging users to transition to the `system.compute` schema. This change is part of Databricks' ongoing efforts to streamline system table management and improve operational data accessibility. System tables are utilized for monitoring costs, auditing security events, and tracking compute performance across the Databricks environment.

Why it matters

This update is crucial for maintaining an organized and efficient data management system, reducing potential confusion from deprecated schemas. By consolidating to the `system.compute` schema, organizations can enhance their operational oversight, ensuring better governance and compliance while optimizing resource usage.

Key capabilities
Enhanced Data Monitoring
Utilize system tables to monitor costs and performance metrics effectively.
Improved Security Auditing
Audit security events through accessible system tables for better compliance.
Streamlined Schema Management
Transitioning to a single schema simplifies data management and reduces errors.
Historical Observability
Access historical data for comprehensive insights into operational activities.
Prerequisites
Workspace must be enabled for Unity Catalog.
Metastore must be on Unity Catalog Privilege Model Version 1.0.
Recommended use cases
Monitoring compute resource usage over time.Auditing and tracking security events across workspaces.Analyzing billing and usage data for cost optimization.
Limitations · remember
!Only a subset of system tables is available in AWS GovCloud.
!System tables are read-only and cannot be modified.
Architecture
Unity Catalog → System Catalog → System Tables → Operational Data Store
Get started
1
Identify Legacy Schema Usage
Review existing queries and applications that utilize the `compute_preview` schema.
