Optimize validation for large datasets

**Description**
Currently types lacks proper sorting support.

**Proposed solution**
Add configurable sorting with sensible defaults.

**Priority**: Low/Medium

No files, tests, or entry points are named. Start by locating validation and type-handling code, then trace where sorting could be configured for large datasets. Done means sensible defaults and configurable sorting are implemented, with validation behavior checked on large datasets.
