Standard Config Table Per Service

Configuration tags

{
	configTag: "VariantHandlerServiceNameTag"
	configKey: "VariantHandlerServiceNameTag"
	configValue: xxx // this own services ServiceNameTag, eg "VariantStandard"
}

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

{
	configTag: "VariantManagerServiceName"
	configKey: "VariantManagerServiceName"
	configValue: xxx // eg: "ProductManager"
}

LogicalResults

Stores results for any requests to perform logical searches on variant data

{
	resultId: xxx // eg: filterMainId for a single logical element
	dataId: xxx // one variantId
}

• partition key: resultId
• sort key: dataId

Nodes

{
	nodeLabel: "{VariantStandardLib.VARIANT_GRAPH_NODE_LABEL}",
	schema: {
		identifier: true,
		restrictProperties: true,
		restrictRelationships: true,
		properties: {
			variantId: {
				identifier: true, //(random uuid)
			},
			variantHandlerServiceNameTag: {
				immutable: true,
			},
		},
	}
}

{
	nodeLabel: "{VariantStandardLib.VARIANT_PRODUCT_LINK_GRAPH_NODE_LABEL}",
	schema: {
		identifier: true,
		restrictProperties: true,
		restrictRelationships: true,
		properties: {
			variantId: {
				immutable: true,
			},
			variantHandlerServiceNameTag: {
				immutable: true,
			},
			productId: {
				immutable: true,
			},
			productHandlerServiceNameTag: {
				immutable: true,
			},
		},
	}
}

• adds a node between each variant to product relationship, we do this so we can add variantProductLink specific relationships, eg to media that only relates to this link, not to other parent variants the product has

Relationships

{
	relationshipType: "{VariantStandardLib.createHasVariantProductLinkGraphRelationshipType()}", // "hasVariantProductLink"
	schema: {
		elementCanBeRemoved: true,
		allPropertiesImmutable: true,
		restrictProperties: true,
		properties: {
			originTimestamp: //timestamp the request to create/change this relationship was sent
		},
	}
}

{
	relationshipType: "{VariantStandardLib.createDisabledVariantProductLinkGraphRelationshipType()}", //"disabledVariantProductLink"
	schema: {
		elementCanBeRemoved: true,
		allPropertiesImmutable: true,
		restrictProperties: true,
		properties: {
			originTimestamp: //timestamp the request to create/change this relationship was sent
		},
	}
}

• links variant to a variantProductLink, or a variantProductLink to a product
