Methods

AddWriteStore(IServiceCollection, IConfiguration)

Binds EventSourcingOptions from the EventSourcing configuration section, the section for write-side settings.

public static IServiceCollection AddWriteStore(this IServiceCollection services, IConfiguration configuration)

Parameters

services IServiceCollection: The service collection to register options on.
configuration IConfiguration: The host configuration providing the options section.

Returns

IServiceCollection: The same IServiceCollection for chaining.

Examples

services.AddWriteStore(configuration);

// Snapshot cadence is a strategy, not a key: every 100 events instead of the default 50.
services.AddSingleton<ISnapshotStrategy>(new VersionThresholdSnapshotStrategy(threshold: 100));

Remarks

The section holds EventSourcing:AppendAgainstAggregatedVersion and EventSourcing:NewStreamOwnerFromSession. AddEventSourcing() binds the same section from the container's configuration and validates the policy at start; a host that calls both and passes this method another configuration gets the value of whichever registration comes later. How often an aggregate is snapshotted is not configuration: it is the registered ISnapshotStrategy.
