One of the following may be specified:All,Read,ReadWrite,Write.tableEnvironmentVariableName?stringOptional Name for the Lambda function environment variable set to the name of the DynamoDB table. Default: DDB_TABLE_NAMEexistingVpc?ec2.IVpcAn optional, existing VPC into which this pattern should be deployed. When deployed in a VPC, the Lambda function will use ENIs in the VPC to access network resources and a Gateway Endpoint will be created in the VPC for Amazon DynamoDB. If an existing VPC is provided, thedeployVpcproperty cannot betrue. This usesec2.IVpcto allow clients to supply VPCs that exist outside the stack using theec2.Vpc.fromLookup()method.vpcProps?ec2.VpcPropsOptional user-provided properties to override the default properties for the new VPC.enableDnsHostnames,enableDnsSupport,natGatewaysandsubnetConfigurationare set by the pattern, so any values for those properties supplied here will be overridden. IfdeployVpcis nottruethen this property will be ignored.deployVpc?booleanWhether to create a new VPC based onvpcPropsinto which to deploy this pattern. Setting this to true will deploy the minimal, most private VPC to run the pattern:One isolated subnet in each Availability Zone used by the CDK programenableDnsHostnamesandenableDnsSupportwill both be set to trueIf this property istruethenexistingVpccannot be specified. Defaults tofalse.Pattern PropertiesNameTypeDescriptionlambdaFunctionlambda.FunctionReturns an instance of lambda.Function created by the constructdynamoTabledynamodb.TableReturns an instance of dynamodb.Table created by the constructvpc?ec2.IVpcReturns an interface on the VPC used by the pattern (if any). This may be a VPC created by the pattern or the VPC supplied to the pattern constructor.Default settingsOut of the box implementation of the Construct without any override will set the following defaults:AWS Lambda FunctionConfigure limited privilege access IAM role for Lambda functionEnable reusing connections with Keep-Alive for NodeJs Lambda functionEnable X-Ray TracingSet Environment Variables(default) DDB_TABLE_NAMEAWS_NODEJS_CONNECTION_REUSE_ENABLED (for Node 10.x and higher functions)Amazon DynamoDB TableSet the billing mode for DynamoDB Table to On-Demand (Pay per request)Enable server-side encryption for DynamoDB Table using AWS managed KMS KeyCreates a partition key called 'id' for DynamoDB TableRetain the Table when deleting the CloudFormation stackEnable continuous backups and point-in-time recoveryArchitecture© Copyright Amazon.com, Inc. or its affiliates.
