Excalibur.Data.IdentityMap.SqlServer
SQL Server implementation of the Excalibur aggregate identity map store.
Setup
1. Create the table
CREATE TABLE [dbo].[IdentityMap] (
ExternalSystem NVARCHAR(128) NOT NULL,
ExternalId NVARCHAR(256) NOT NULL,
AggregateType NVARCHAR(256) NOT NULL,
AggregateId NVARCHAR(256) NOT NULL,
CreatedAt DATETIMEOFFSET NOT NULL CONSTRAINT DF_IdentityMap_CreatedAt DEFAULT SYSUTCDATETIME(),
UpdatedAt DATETIMEOFFSET NOT NULL CONSTRAINT DF_IdentityMap_UpdatedAt DEFAULT SYSUTCDATETIME(),
-- NONCLUSTERED is required, not a preference: this triple is 1280 bytes, past SQL Server's
-- 900-byte CLUSTERED key cap and inside the 1700-byte NONCLUSTERED one. Declared CLUSTERED,
-- the table is created with only a warning and then rejects any row whose key exceeds 900
-- bytes -- so a long external id fails on first write rather than at deployment.
CONSTRAINT PK_IdentityMap PRIMARY KEY NONCLUSTERED (ExternalSystem, ExternalId, AggregateType),
INDEX CIX_IdentityMap_External CLUSTERED (ExternalSystem, ExternalId),
INDEX IX_IdentityMap_AggregateId (AggregateType, AggregateId)
);
2. Register the provider
services.AddIdentityMap(identity =>
{
identity.UseSqlServer(sql =>
{
sql.ConnectionString(connectionString)
.SchemaName("dbo")
.TableName("IdentityMap");
});
});
Features
- No TVPs required -- batch lookups use parameterized IN clauses
- Configurable batch size -- default 100, automatically chunks larger batches
- MERGE-based upsert -- atomic bind operations
- Conflict detection -- TryBind detects duplicate key violations and returns existing mappings

Database schema
This package does not create its tables. The DDL ships inside the .nupkg under scripts/, and
you apply it — so a schema change to your database is always something you did deliberately, never
something a version upgrade did to you while you were not looking.
| Script |
|---|
scripts/CreateIdentityMapTable.sql |
Apply them in filename order before starting the application, and again — for any new ones — before starting a new version after an upgrade.
The scripts/ folder lives inside the package, not in your build output. To read it:
# the package folder, then the scripts inside it
dotnet nuget locals global-packages --list
ls ~/.nuget/packages/excalibur.data.identitymap.sqlserver/<version>/scripts/
The folder is authoritative. If any list of scripts — including this one — disagrees with what is actually in the package you installed, the package is right.
