Optimize middleware for large datasets

**Description**
Currently controllers lacks proper caching support.

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

**Priority**: Low/Medium

Start by locating the controller and middleware entry points and checking whether the project already has any caching configuration or conventions. Define the supported configuration, sensible defaults, and the behavior expected for large datasets; the work is done when controllers use configurable caching without changing unrelated behavior.
