DynamoDB tables

Standard Config Table Per Service

Configuration tags

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

{
	configKey: "PaymentMethodHandlerService"
	configTag: xxx // paymentMethodHandlerServiceNameTag, eg: "PaymentMethodGeneric"
	configValue: {
		serviceName: xxx // eg: "PaymentMethodGeneric", this is the actual deployed service name
	}
}

paymentMethod

Records which Handler manages each payment method

{
	paymentMethodId,
    currencyId,
	paymentMethodHandlerServiceNameTag
}

• partition key: paymentMethodId
• sort key: (none)
• all Handler services are expected to create a paymentMethod node in the shared Products graph

UserPaymentMethods

Records which Handler manages each user payment method

{
	userPaymentMethodId
	paymentMethodHandlerServiceNameTag
}

• partition key: userPaymentMethodId
• sort key: (none)
• all Handler services are expected to create a userPaymentMethod node in the shared Products graph

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: "managerPaymentMethod" //unique id is paymentMethodId
	type: "group",
	elements:
	[
		{
			type: "logical",
			logicalTag: "currencyId",
			comparison: "equals",
			value: "xx"
		},
		{
			type: "complexFilter",
			complexFilter: {
				filterType: "paymentMethodProperty",
				// see [[NPM module - Izara Core - Property Node|Complex Filter requests]]
			}
		},
		{
			type: "complexFilter",
			complexFilter: {
				filterType: "paymentMethodNameTranslation" //unique id is paymentMethodId
				type: "group",
				elements: 
				[
					{
						// see [[Service - Translations|Complex Filter requests]]
						type: "logical",
						logicalTag: "textTag_languageId_text",
						resultType: "paymentMethod",
						textTag: "paymentMethodName",
						languageId: "en",
						text: "Is a great term",
						subjectIdentifierPropertyName: "paymentMethodId",
						caseSensitive: true
					},
				]
			}
		},		
		...
	]
}

{
	filterType: "managerUserPaymentMethod" //unique id is userPaymentMethodId
	type: "group",
	elements:
	[
		{
			type: "logical",
			logicalTag: "paymentMethodId",
			comparison: "equals",

		},
		{
			type: "complexFilter",

		},

			complexFilter: {
