Optimize validation for large datasets

**Description**
Currently store lacks proper monitoring support.

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

**Priority**: Low/Medium

No files, tests, or entry points are named. First clarify the mismatch between the title's validation optimization and the description's monitoring request, then locate the store and existing monitoring behavior; done should include agreed configuration options and sensible defaults.
