Optimize routes for large datasets

**Description**
Currently handlers lacks proper logging support.

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

**Priority**: Low/Medium

The issue names no files, tests, or entry points, and its title conflicts with the logging description. Start by locating the handlers and existing logging configuration, then determine how configuration and defaults are currently loaded. Done means handlers support configurable logging with documented sensible defaults and the relevant checks pass.
