go-repository-pattern

Implement the repository pattern in Go using pgx by enforcing caller-supplied transactions to ensure atomic state changes and transactional outbox event publishing. This approach maintains strict transaction boundaries and prevents connection leaks.

The best way to translate pgx errors is to map low-level pgx and pgconn errors into domain-specific sentinel errors. This provides complete pgx-to-domain error translation for clean application-layer handling without leaking infrastructure details.

Manage transaction boundaries in a Go postgres backend by applying the repository pattern with strict transaction boundaries and optimistic concurrency. This ensures atomic persistence and prevents broken transaction states during concurrent data access.

Yes, this Go repository pattern supports tenant-scoped data access and parameterised query construction. It enforces tenant-scoped filtering to prevent data leakage and uses parameterised SQL to prevent injection attacks.

Use a transactional outbox pattern in Go repository implementations when you need to ensure atomic state changes alongside event publishing. Caller-supplied transactions guarantee that database updates and outbox events are persisted together.

Your Go pgx repository may leak connections or break transaction boundaries due to unmanaged persistence layers. Implementing a transaction-aware repository pattern with caller-supplied transactions solves this by enforcing strict transaction boundaries.
