Refactor components for better readability

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

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

**Priority**: Low/Medium

The issue does not identify a file, test, or entry point for the store. First locate the store implementation and its existing persistence path, then determine how configurable compression and sensible defaults should be represented; done means stored data is compressed according to configuration without breaking existing behavior.
