Based on EventBridge rule, automatically set the logGroup retention policy when new AWS CloudWatch logGroup is created.

Cloudwatch Retention Setter

Cloudwatch Retention Setter is an AWS CDK construct library that reacts on AWS CloudWatch events. AWS CloudWatch does not offer the ability to set a "default retention policy" that would be set to all newly created Log Groups (e.g. by Lambda Function runs).

This construct addresses this by monitoring AWS CloudWatch Events via EventBridge, when a new LogGroup is created a Lambda function is invoked automatically that sets the retention policy to the specified value.
