From 5e3ade2c51a97d3bf4ba4690e4d52f93324596c0 Mon Sep 17 00:00:00 2001 From: Lewis-Lyons <69603730+Lewis-Lyons@users.noreply.github.com> Date: Thu, 11 Sep 2025 18:22:58 -0400 Subject: [PATCH 1/7] feat: Add AUDIT_ONLY model kind for multi-table validation Introduces a new model kind that validates data relationships across multiple tables without materializing results. Combines model benefits (DAG participation, dependencies) with audit behavior (validation only). - Add AUDIT_ONLY to ModelKindName enum and create AuditOnlyKind class - Implement AuditOnlyStrategy for execution without materialization - Add comprehensive unit and integration tests - Update documentation with usage examples and best practices - Add three example models to sushi project demonstrating use cases --- docs/concepts/audits.md | 101 +++++++ docs/concepts/models/model_kinds.md | 109 +++++++ docs/reference/model_configuration.md | 11 + .../sushi/models/audit_duplicate_orders.sql | 43 +++ .../sushi/models/audit_order_integrity.sql | 25 ++ .../models/audit_waiter_revenue_anomalies.sql | 47 +++ sqlmesh/core/dialect.py | 1 + sqlmesh/core/model/kind.py | 39 ++- sqlmesh/core/snapshot/definition.py | 2 +- sqlmesh/core/snapshot/evaluator.py | 88 ++++++ tests/core/test_integration.py | 267 +++++++++++++++++- tests/core/test_model.py | 159 +++++++++++ 12 files changed, 889 insertions(+), 3 deletions(-) create mode 100644 examples/sushi/models/audit_duplicate_orders.sql create mode 100644 examples/sushi/models/audit_order_integrity.sql create mode 100644 examples/sushi/models/audit_waiter_revenue_anomalies.sql diff --git a/docs/concepts/audits.md b/docs/concepts/audits.md index a5a9fccc49..1e037553dd 100644 --- a/docs/concepts/audits.md +++ b/docs/concepts/audits.md @@ -722,3 +722,104 @@ MODEL ( ) );

-## Summary -This PR introduces a new `AUDIT_ONLY` model kind to SQLMesh, addressing the gap in validating relationships between multiple tables without materializing unnecessary tables. This feature combines the benefits of models (DAG participation, dependencies, scheduling) with audit behavior (validation without materialization). - -## Problem Statement -Previously, SQLMesh users had to choose between: -- Creating wasteful materialized models just to run cross-table validations -- Using standalone audits that don't integrate well with model dependencies -- Building external validation systems outside SQLMesh - -## Solution -The `AUDIT_ONLY` model kind enables users to: -- Validate relationships across multiple tables (e.g., referential integrity) -- Run complex validation queries that don't belong to a single model -- Participate in the model DAG with proper dependencies -- Avoid creating unnecessary materialized tables - -## Implementation Details - -### Core Changes - -#### 1. Model Kind Definition (`sqlmesh/core/model/kind.py`) -- Added `AUDIT_ONLY` to `ModelKindName` enum -- Created `AuditOnlyKind` class with configuration: - - `blocking` (default: `True`): Whether failures stop the pipeline - - `max_failing_rows` (default: `10`): Number of sample rows in error messages -- Marked as `is_symbolic=True` (no materialization) - -#### 2. Execution Strategy (`sqlmesh/core/snapshot/evaluator.py`) -- Created `AuditOnlyStrategy` extending `SymbolicStrategy` -- Executes validation query and checks for returned rows -- Raises `AuditError` with sample data if validation fails -- Properly integrated with the evaluation strategy routing - -#### 3. Parser Support (`sqlmesh/core/dialect.py`) -- Added `AUDIT_ONLY` to list of model kinds that accept properties - -#### 4. Snapshot Definition (`sqlmesh/core/snapshot/definition.py`) -- Fixed `evaluatable` property to include audit-only models -- Ensures proper interval tracking for validation execution - -### Testing - -#### Unit Tests (`tests/core/test_model.py`) -- 6 unit tests covering: - - Basic parsing and properties - - Blocking/non-blocking configuration - - Max failing rows configuration - - Python model support - - Full configuration scenarios - - Serialization/deserialization - -#### Integration Tests (`tests/core/test_integration.py`) -- 6 integration tests validating: - - Validation success/failure scenarios - - Blocking vs non-blocking behavior - - Dependency tracking - - Scheduling with cron - - Metadata changes - -### Documentation - -#### User Documentation Updates -- **`docs/concepts/audits.md`**: Added comprehensive AUDIT_ONLY section under Advanced Usage -- **`docs/concepts/models/model_kinds.md`**: Added detailed AUDIT_ONLY section with examples -- **`docs/reference/model_configuration.md`**: Added AUDIT_ONLY configuration reference - -#### Example Models (`examples/sushi/models/`) -Added 3 demonstration models (all non-blocking for demo purposes): -- `audit_order_integrity.sql`: Validates referential integrity -- `audit_waiter_revenue_anomalies.sql`: Detects revenue anomalies -- `audit_duplicate_orders.sql`: Identifies duplicate orders - -## Usage Example - -```sql -MODEL ( - name data_quality.order_validation, - kind AUDIT_ONLY ( - blocking TRUE, - max_failing_rows 20 - ), - depends_on [orders, customers], - cron '@daily' -); - --- Query returns 0 rows for success -SELECT - o.order_id, - o.customer_id, - 'Missing customer record' as issue -FROM orders o -LEFT JOIN customers c ON o.customer_id = c.customer_id -WHERE c.customer_id IS NULL;

charset=UTF-8 Content-Transfer-Encoding: 8bit AUDIT_ONLY models are symbolic and don't create physical tables, but they still need to be included in plans so their validation queries can run. Changes: - Exclude symbolic models from missing_intervals in Plan to prevent them from being scheduled for backfill - Update integration tests to filter out AUDIT_ONLY models when counting new snapshots and checking intervals - Fix test validation to skip table existence checks for symbolic models - Distinguish between AUDIT_ONLY and EXTERNAL models (both symbolic but EXTERNAL models still track intervals) This ensures AUDIT_ONLY models serve their validation purpose without participating in the physical deployment lifecycle. 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude --- sqlmesh/core/plan/definition.py | 2 +- tests/core/test_integration.py | 61 +++++++++++++++++++++------------ 2 files changed, 40 insertions(+), 23 deletions(-) diff --git a/sqlmesh/core/plan/definition.py b/sqlmesh/core/plan/definition.py index aaf6ec5dc0..ac854bcc8c 100644 --- a/sqlmesh/core/plan/definition.py +++ b/sqlmesh/core/plan/definition.py @@ -187,7 +187,7 @@ def missing_intervals(self) -> t.List[SnapshotIntervals]: end_bounded=self.end_bounded, ignore_cron=self.ignore_cron, ).items() -
