Validio 8.2 introduces validator rerun, lineage edge suggestions, description generation, integrations for OpenLineage and Teradata, and a new validator to count record matches.

Rerun Validators to Verify Data Fixes

You can now rerun validators to re-execute validation on recent data while preserving all existing metrics, incidents, and audit history. This non-destructive action is designed for verifying data fixes after remediation — particularly useful where a complete audit trail is required.

• Rerun individual validators from the Validators page, Source Validators tab, or Validator details page. On the metric graph, click a specific datapoint to rerun from that window. A confirmation dialog lets you include related validators that share the same pipeline configuration. See Managing Validators.
• Rerun all validators on a source from the Sources page or Source details page to re-execute all eligible validators at once. See Managing Sources.

When a rerun completes, the new metric value is stored alongside the original. If the rerun value falls within the configured bounds, the incident is automatically resolved. Rerun history is visible in the metric graph tooltip and the incidents list.

AI Lineage Edge Suggestions

You can now use AI-powered matching to automatically suggest field-level lineage connections between assets from different systems. The Suggest Edges workflow combines fast heuristic rules with optional LLM refinement to find matches even when field names differ — handling casing, abbreviations, naming conventions, and semantic equivalents. Suggestions are grouped by confidence level (high, medium, low) with explanations, so you can review and accept the right matches.

An LLM credential is optional but recommended for deeper semantic analysis. For details, see Suggest Lineage Edges in our product documentation.

AI Description Generation

You can now use AI to generate descriptions for catalog assets, schema fields, glossary terms, domains, validators, and lineage edges. The AI analyzes available metadata — such as schema information, glossary terms, tags, and lineage context — to produce tailored descriptions. A bulk generation option lets you describe multiple schema fields at once, with a review dialog to select which descriptions to keep. Generated descriptions use markdown formatting and can be refined in the built-in editor before saving.

Requires AI features and an LLM credential to be configured. For details, see AI Description Generation in our product documentation.

OpenLineage Integration

Validio now supports ingesting lineage events from OpenLineage-compatible tools such as Apache Airflow, Spark, and dbt. Point your OpenLineage producer at the Validio endpoint, and Validio automatically creates catalog assets, establishes lineage relationships, and imports dataset metadata from incoming events.

For more details, see OpenLineage in our product documentation.

Teradata Integration

You can now connect Validio to Teradata for automated data quality monitoring. Set up a read-only service account, configure a credential, and add sources to validate your Teradata data. The integration supports catalog discovery, lineage, custom SQL sources, and all standard Teradata data types.

For details, see Teradata in our product documentation.

Record Match Count Validator

A new Record Match Count validator type is available under Metrics & Validity. Use it to count the records matching a specific filter condition — for example, monitoring how many orders have a status of "failed" or how many records contain a particular flag.

For details, see Record Match Count in our product documentation.
