Excalibur.EventSourcing.SqlServer

SQL Server implementation of event sourcing infrastructure for the Excalibur framework.

Part Of

This package is included in the following metapackages:

Metapackage	Tier	What It Adds
`Excalibur.Dispatch.SqlServer`	Starter	+ Dispatch core + Outbox + Hosting
`Excalibur.SqlServer`	Complete	+ Inbox + Saga + Leader Election + Audit + Compliance + Data

Tip: Install Excalibur.SqlServer for a production-ready SQL Server stack with a single package reference.

Installation

dotnet add package Excalibur.EventSourcing.SqlServer

Features

SqlServerEventStore - Dapper-based event store implementation
SqlServerSnapshotStore - SQL Server snapshot persistence
Optimized for high-throughput event streaming
Connection factory pattern for multi-database scenarios
AOT-compatible with full Native AOT support
NO Entity Framework Core dependency

Usage

// Recommended: Builder-integrated registration
services.AddExcalibur(x => x.AddEventSourcing(es =>
{
    es.UseSqlServer(options =>
    {
        options.ConnectionString = connectionString;
        options.EventStoreSchema = "events";
    });
    es.AddRepository<OrderAggregate, Guid>(id => new OrderAggregate(id));
}));

// Alternative: Direct registration
services.AddSqlServerEventSourcing(options =>
{
    options.ConnectionString = connectionString;
});

Database Schema

The store does not create its tables at runtime. Provision them before the first append, by running the scripts shipped inside this package under scripts/:

Script	Creates	Required
`scripts/001_CreateEventStoreSchema.sql`	`dbo.EventStoreEvents`	Yes — this is the event store itself
`scripts/002_CreateSnapshotSchema.sql`	`dbo.EventStoreSnapshots`	Only if you enable snapshots
`scripts/003_MigrateToMultiTenant.sql`	—	Upgrade only, see below
`scripts/004_MakeEventTenantTotal.sql`	—	Upgrade only, see below

Both create scripts are guarded, so re-running them against an existing database is a no-op.

Upgrading an existing database

Run these in order; each is guarded and safe to run against a database that is already converged.

003_MigrateToMultiTenant.sql grows a store created before tenancy existed into the current schema. Without it, an existing deployment fails on the first append with Invalid column name 'TenantId'.

004_MakeEventTenantTotal.sql then backfills EventStoreEvents.TenantId from NULL to the reserved __untenanted__ sentinel and makes the column NOT NULL, so an untenanted event is a value rather than a missing one, and an upgraded database ends up in the same shape as a fresh one. It is not needed for a fresh install — 001 already creates the column that way. Its pre-flight step reports any stream version that already holds both a NULL and a literal sentinel row; resolve those before continuing, because only you can decide which append survives.

Both upgrade scripts rebuild a unique constraint on the system of record, so run them in a maintenance window with the store stopped, against a backup you have restored at least once.
