Introduction

This tool verifies the integrity of dataset outputs and monitors execution attributes to ensure that every run meets expected quality thresholds. It is built for teams who rely on automated data pipelines and need immediate visibility into issues such as missing items, failed runs, or schema mismatches.

Automated Data Quality Monitoring

• Validates run status and ensures it completes successfully.
• Checks that minimum output requirements are met.
• Supports JSON schema validation for consistent data structures.
• Compares results with previous executions to detect anomalies.
• Sends notifications or triggers fallback automations when errors occur.

Features

Feature	Description
Run Status Validation	Confirms that execution completed successfully and flags abnormal run states.
Minimum Output Checks	Ensures datasets produce enough items to be considered valid.
Schema Validation	Compares each item against a defined JSON schema for structural accuracy.
Difference Detection	Compares results against previous runs to detect unexpected changes.
Custom Error Notifications	Sends alerts to configured recipients or triggers additional automation.
Flexible Webhook Support	Easily integrates with task or actor automation workflows.

Use Cases

• Data engineering teams use it to validate pipeline outputs so they can ensure downstream systems receive complete and correct data.
• Automation developers use it to monitor scraper stability so they can catch unexpected failures early.
• QA engineers use it to confirm schema consistency so they can maintain predictable data formats.
• Business analysts rely on it to verify key datasets before processing so they can avoid corrupted analytics.

FAQs

Q: Can I validate only a subset of results? Yes. The tool supports configuring sampleCount to limit how many items are inspected.

Q: Does it work without a schema? Absolutely. Schema validation is optional—only the checks you configure will run.

Q: Can it trigger other automations when errors occur? Yes. You can specify actions for both success and failure scenarios using runActOnSuccess and runActOnError.

Q: Does it support legacy systems? It can validate previous execution results and integrate through legacy webhooks if necessary.
