## PR Description
This PR introduces a unified storage parameter handling mechanism for
storage-related functionalities, including Export, Table-Valued Functions
(TVF), and Backup. The key objective is to decouple business logic from the
underlying storage implementation, ensuring that the business layer only
focuses on its domain logic while storage parameters manage the interaction
with the storage system.
##Key Changes
### Centralized Storage Parameter Management:
Instead of handling storage configurations in multiple places, storage
parameters now serve as the sole interface between the business logic and the
storage layer. This improves maintainability, avoids scattered storage-related
logic, and simplifies future storage extensions. ### Separation of Concerns:
The business layer is storage-agnostic, meaning it does not need to handle
storage-specific details. Storage parameters are responsible for translating
high-level storage configurations into system-specific settings. ### Phase 1
Implementation:
This PR focuses on integrating Export, TVF, and Backup with the new storage
parameter mechanism. Subsequent PRs will address Broker and additional
components, ensuring a smooth and incremental migration. ##Next Steps
Gradually extend this unified approach to Broker and other storage-dependent
functionalities. Continue refining the abstraction to support future storage
systems with minimal modifications. ## Why This Change?
Enhances maintainability by consolidating storage-related logic. Improves
extensibility for future storage backends. Simplifies business logic, ensuring
a cleaner separation of concerns.
