compendium-adapter-postgresql

PostgreSQL adapter for the Compendium event-sourcing framework. JSONB-backed event store + projection checkpoint store + streaming event store + saga process-manager repository, all on raw Npgsql.

Extracted from sassy-solutions/compendium per ADR-0006 (multi-repo adapter split). Built from template-compendium-adapter-dotnet.

What's in this package

Component Implements Purpose
PostgreSqlEventStore IEventStore Durable event storage with optimistic concurrency, tenant isolation, JSONB payload
PostgreSqlStreamingEventStore IStreamingEventStore Global-position cursor for projection rebuilds + live processing
PostgreSqlProjectionStore IProjectionStore Projection checkpoints + snapshots + state
PostgreSqlProjectionCheckpointStore IProjectionCheckpointStore Fine-grained per-(projection, aggregate) checkpoints
PostgresProcessManagerRepository IProcessManagerRepository Durable saga state with typed-state reload
RowLevelSecurityExtensions — SQL-injection-safe tenant filter construction

Install

dotnet add package Compendium.Adapters.PostgreSQL

services.AddPostgreSqlEventStore(builder.Configuration.GetSection("Postgres"));

See docs/README.md for full configuration (connection string, schema name, table name, BatchSize, multi-tenancy).

Versioning

This package continues the version sequence of Compendium.Adapters.PostgreSQL originally published from the framework monorepo (last framework-published version: 1.0.0-preview.8). The first release from this repo is v1.0.0-preview.9. Versions are driven by git tags via MinVer — see docs/RELEASE.md.

Repository conventions

Aspect Choice
Target .NET 9, C# 13
DB driver Npgsql 9.0.x + Dapper 2.1.x
Test framework xUnit 2.9.3 + FluentAssertions 6.12.1 + NSubstitute 5.1.0
Integration tests Testcontainers 4.11.0 (Docker required)
Coverage gate 199 unit tests, 90 %+ line coverage on the unit-testable surface
Result pattern Result<T> from Compendium.Core

Build & test locally

# Unit tests — no Docker required.
dotnet test --filter "FullyQualifiedName!~IntegrationTests"

# Integration tests — Docker must be running (TestContainers spins up PostgreSQL).
dotnet test --filter "FullyQualifiedName~IntegrationTests"

The integration suite covers PG-specific behaviour that can't be tested against an in-memory implementation: JSONB serialisation round-trip, schema bootstrap, WHERE global_position > @x cursor semantics, tenant-filter SQL injection, snapshot UPSERT, process-manager state-row updates.
