DynamoDB tables

Standard Config Table Per Service

Configuration tags

{
	configKey: "ProductGraphServiceName"
	configTag: "ProductGraphServiceName"
	configValue: xxx // eg: "ProductGraph"
}

{
	configKey: "DeliveryMethodHandlerService"
	configTag: xxx // deliveryMethodHandlerServiceNameTag, eg: "DeliveryMethodStandard"
	configValue: {
		serviceName: xxx // eg: "DeliveryMethodStandard", this is the actual deployed service name
	}
}

DeliveryMethodRecord

Records which Handler manages each payment method

{
	deliveryMethodId
	deliveryMethodHandlerServiceNameTag
}

• partition key: deliveryMethodId
• sort key: (none)

Complex Filter requests

• Not yet used at the Manager level, would send requests to all handlers, could perhaps setup to automatically pass on processLogical requests to all handlers, and not have a processLogical function in the Manager service

{
	filterType: "managerDeliveryMethod" //unique id is deliveryMethodId
	type: "group",
	elements:
	[
		{
			type: "logical",
			logicalTag: "currencyId",
			comparison: "equals",
			value: "xx"
		},
		{
			type: "logical",
			logicalTag: "fromLocationNodeId",
			comparison: "equals",
			value: "xx"
		},
		{
			type: "complexFilter",
			complexFilter: {
				filterType: "deliveryMethodProperty",
				// see [[NPM module - Izara Core - Property Node|Complex Filter requests]]
