SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve?

This Skill clarifies the complex repository and data store patterns used across the Ark ecosystem, making it easier to understand how data is managed and accessed.

Core Features & Use Cases

Architecture Deep Dive: Explains hexagonal architecture, ports/adapters, and RepoManager aggregators.
Data Store Variety: Details multi-backend support (BadgerDB, SQLite, PostgreSQL) and live stores for ephemeral state.
Use Case: When working on the arkd service, understand how its RepoManager interface abstracts different data storage implementations like BadgerDB or PostgreSQL.

FAQPage Schema

What is hexagonal architecture and how does it apply to the Ark repository pattern?▼

The Ark ecosystem supports multi-backend database patterns, including BadgerDB, SQLite, and PostgreSQL. It also uses live stores to manage ephemeral state and event channels for reactive updates across services.

How do I use RepoManager aggregators to abstract different database backends in arkd?▼

You use RepoManager aggregators in arkd to abstract different data storage implementations like BadgerDB or PostgreSQL. This interface centralizes data access, allowing your service to switch backends without changing core logic.

Does the Ark go-sdk support live stores for ephemeral state and reactive updates?▼

Yes, the Ark go-sdk supports live stores specifically for managing ephemeral state. It also utilizes event channels to provide reactive updates across services like arkd and fulmine.

When should I use live stores instead of persistent database backends in the Ark protocol?▼

Use live stores in the Ark protocol when you need to manage ephemeral state that does not require persistent disk storage. For long-term data, use multi-backend database support like BadgerDB, SQLite, or PostgreSQL.

What is the best way to structure data access across arkd and fulmine using ports and adapters?▼

The best way to structure data access across arkd and fulmine is using the ports and adapters pattern. This hexagonal architecture isolates core application logic from specific database implementations, ensuring modular services.
