Optimize components for large datasets

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

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

**Priority**: Low/Medium

Start by locating the handlers responsible for processing large datasets and inspect their current data flow. The issue does not name files, tests, or a compression format; completion would require configurable compression with sensible defaults and verification that large-dataset handling still works.
