Backend infrastructure for the Merlin application.

The backends package provides a unified interface and implementations for persisting and retrieving Merlin's core data entities (such as studies, runs, and workers) across various storage technologies. It defines an abstract backend interface (ResultsBackend) along with concrete implementations using Redis and SQLite, as well as utility functions, store abstractions, and a backend factory.

Subpackages

redis: Redis-based backend implementation, including store classes and a Redis-backed ResultsBackend. sqlite: SQLite-based backend implementation, with support for persistent local storage of Merlin data models.

Modules:

Name	Description
backend_factory	Contains MerlinBackendFactory, used to dynamically select and instantiate a backend.
results_backend	Defines the abstract ResultsBackend base class for backend implementations.
store_base	Provides the abstract StoreBase class, the foundation for all store implementations.
utils	Utility functions for serialization, deserialization, and error handling across backends.

This package serves as the backend layer in Merlin's architecture, enabling flexible, pluggable data persistence with a consistent API regardless of the underlying storage engine.
