Optimize lib for large datasets

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

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

**Priority**: Low/Medium

Start by locating the handlers referenced in the issue and read how they currently manage execution. Define the configurable timeout and sensible defaults, then verify that handlers honor the setting and default behavior; the issue does not name specific files or tests.
