Expanded validation capabilities for rules

Validation rules now support more expressive conditions, enabling stricter and more precise data checks.

What’s available

This release introduces two new capabilities to validation rules:

• Matches pattern operator: You can now validate text fields using regular expressions through a new matches pattern operator. Currently available in pullup, with pushdown support coming soon. This operator relies on the CEL matches string method and follows the RE2 standard. A negation version of the operator is also available.
• Closed lookup reference values: You can now define a fixed list of allowed reference values directly within a validation rule. These values are scoped to the rule itself and are not reusable across other rules. A negation version of the operator is also available.

Why this matters

These enhancements make validation rules more expressive and self-contained, allowing teams to enforce stricter constraints on text formats and accepted values while keeping rule definitions clear and easy to manage.
