EventStore provides the builtin index models for the MongoDB event store.

Functions

func EventStoreCore

func EventStoreCore() []mongo.IndexModel

EventStoreCore returns the core index models for the MongoDB event store.

func EventStoreEdge

func EventStoreEdge() []mongo.IndexModel

EventStoreEdge returns all edge-case index models for the MongoDB event store.

Types

type EventStoreIndices

type EventStoreIndices struct {

	// ID creates an index for the event id.
	ID mongo.IndexModel

	// Name creates an index for the event name.
	Name mongo.IndexModel

	// NameAndTime creates a compound index for the event name and id.
	NameAndTime mongo.IndexModel

	// AggregateNameAndVersion creates a compound index for the aggregate name and version.
	AggregateNameAndVersion mongo.IndexModel

	// AggregateNameAndIDAndVersion creates a compound index for the aggregate name, id, and version.
	AggregateNameAndIDAndVersion mongo.IndexModel

	// ISOTime creates an index for the ISO time field. Usually, this is not
	// needed because an index is already created for the nano time field.
	ISOTime mongo.IndexModel

	// AggregateID creates an index for the aggregate id.
	AggregateID mongo.IndexModel

	// AggregateVersion creates an index for the aggregate version.
	AggregateVersion mongo.IndexModel

	// NameAndVersion creates a compound index for the event name and version.
	NameAndVersion mongo.IndexModel
}
