Optimize handlers for large datasets

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

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

**Priority**: Low/Medium

Start by locating the components and handlers that process large datasets, then inspect the current data flow for any existing compression support. Done means configurable compression is available with sensible defaults, but the issue does not name files, entry points, or tests to run.
