aws_kinesisanalytics: Configuring a vpc

Description

Hey,

I have looked thoroughly through aws cdk documentation but couldn’t find any way to configure a Kinesis Data Analytics Application with a VPC.

Is there a way to configure the networking of a Kinesis Data Analytics Application (adding vpc + subnets + security group)?

Use Case

This feature is needed in our use case to allow access for the Flink java application to access resources within our VPC. Say we needed to communicate with AmazonMQ that resides in a private subnet, how would our Kinesis Data Analytics Application reach the queue server?

Proposed Solution

I am not sure how this could be implemented but as an end goal I could see a parameter within the aws_kinesisanalytics.CfnApplicationV2.ApplicationConfigurationProperty Object as such:

networking_configuration_property of type:

aws_kinesisanalytics.CfnApplicationV2.NetworkingConfigurationProperty

that accepts the follwing:

vpc:ec2.VPC,
subnets:[ec2.Subnet],
security_group:ec2.SecurityGroup

Other information

I am not certain this is relevant but: I am using Python: 3.6.8 cdk: 1.129.0 (build fb43f89) the issue I based my work upon: https://github.com/aws/aws-cdk/issues/12407 The PR that addressed the above issue: https://github.com/aws/aws-cdk/pull/12464

related to the above but on another note: I found a bug in a generated example under the following construct:

aws_cdk.aws_kinesisanalytics_flink
_# Example automatically generated without compilation. See https://github.com/aws/jsii/issues/826
import aws_cdk.aws_kinesisanalytics_flink as flink

flink_app = flink.Application(self, "Application",
    # ...
    property_groups=PropertyGroups(
        FlinkApplicationProperties={
            "input_stream_name": "my-input-kinesis-stream",
            "output_stream_name": "my-output-kinesis-stream"
        }
    )
)_

In Python ‘PropertyGroups’ is an abstract class that doesn’t accept any params: https://docs.aws.amazon.com/cdk/api/latest/python/aws_cdk.aws_kinesisanalytics_flink/PropertyGroups.html
