Unity Catalog Metric Views
Define reusable, governed business metrics in YAML that separate measure definitions from dimension groupings for flexible querying.
When to Use
Use this skill when:
- Defining standardized business metrics (revenue, order counts, conversion rates)
- Building KPI layers shared across dashboards, Genie, and SQL queries
- Creating metrics with complex aggregations (ratios, distinct counts, filtered measures)
- Defining window measures (moving averages, running totals, period-over-period, YTD)
- Modeling star or snowflake schemas with joins in metric definitions
- Enabling materialization for pre-computed metric aggregations
Prerequisites
- Databricks Runtime 17.2+ (for YAML version 1.1); 17.3+ for semantic metadata (
synonyms/display_name/format) - SQL warehouse with
CAN USEpermissions SELECTon source tables,CREATE TABLE+USE SCHEMAin the target schema
Metric View Lifecycle
| Task | Reference | Load when |
|---|---|---|
| Create | metric-view-advisor.md | Any creation task — the advisor handles the full workflow (profile schema, analyze sources, suggest, deploy). Load create-patterns.md alongside as the YAML spec and pattern reference. |
| YAML spec / patterns | create-patterns.md | Patterns 1–12, full YAML field reference, formatting gotchas, deployment errors, quick reference. Companion to the advisor; also load directly for pattern lookup. |
| Query | query-patterns.md | Writing SQL against a metric view — MEASURE() basics, filters, join rollups, window measures, Rules 1–3. |
| Genie integration | metric-view-advisor.md §Genie Design Rules | One-fact-source rule, base views, domain organization, naming. Agent metadata fields (comment, synonyms, display_name, format) are in create-patterns.md §YAML Field Reference. |
Typical flow: advisor → create → query/validate → Genie integration (if adding to a Genie Agent).
Source-controlled deployment with Declarative Automation Bundles
To source-control a metric view, commit its complete SQL definition and execute it through a bundle-managed SQL job. DABs do not have a native metric-view resource, but a bundle-managed SQL job can apply a committed definition:
# databricks.yml
bundle:
name: orders_metrics
variables:
catalog: { default: main }
schema: { default: default }
warehouse_id: { default: "" }
resources:
jobs:
deploy_orders_metrics:
name: deploy_orders_metrics
parameters:
- name: catalog
default: ${var.catalog}
- name: schema
default: ${var.schema}
tasks:
- task_key: create_metric_view
sql_task:
warehouse_id: ${var.warehouse_id}
file:
path: ../src/orders_metrics.metric_view.sql
Deploy and run:
databricks bundle deploy --target <TARGET> --profile <PROFILE>
databricks bundle run deploy_orders_metrics --target <TARGET> --profile <PROFILE>
See the official metric view bundle example.
