Graph Pruning Lint Rules Overview

Rules

1. UNUSED_FIELDS
   • Identifies and lists all fields that are not being used in the schema.
2. DEPRECATED_FIELDS
   • Detects fields that have been deprecated but have not yet been removed from the schema.
3. REQUIRE_DEPRECATION_BEFORE_DELETION
   • Identifies fields that were deleted without being marked as deprecated beforehand.

Rule Configurations

Severity Level

• Error: If any configured rules are violated, it causes the check operation to fail.
• Warning: If any configured rules are violated, they are flagged as warnings, but they don’t cause the check operation to fail.

Grace Period

This is the time period provided to the fields modified on schema publications, allowing time before enforcing these rules during checks.

Schema Usage Check Period (Enterprise only)

• This is the time period used to check the usage of the field.
• For non-enterprise customers, the value is determined by the limits imposed on the organization according to its current billing plan.
