Use case description

AWS CloudWatch Log has just released a new option for log class at the 26th of November 2023. The new option is to use Infrequent Access log type on storing the logs in CloudWatch. This option is suitable for those who are not using features of CloudWatch Logs other than storing the logs as it enables 50% lower cost for data ingestion. Full announcement of the release is available here

Proposed solution (optional)

Add an additional configuration in the AWS function

functions:
  myCloudWatchLog:
    handler: myCloudWatchLog.handler
    events:
      - cloudwatchLog:
          logGroup: '/aws/lambda/hello'
          filter: '{$.userIdentity.type = Root}'
          logClass: 'Infrequent Access'

Which value will be used in the CloudFormation LogGroupClass as described here. Example:

{
  "Type" : "AWS::Logs::LogGroup",
  "Properties" : {
      "DataProtectionPolicy" : Json,
      "KmsKeyId" : String,
      "LogGroupClass" : String,
      "LogGroupName" : String,
      "RetentionInDays" : Integer,
      "Tags" : [ Tag, ... ]
    }
}

Jared I don’t think it’s related, it’s talking about some other logging feature.

I'm interested in the same feature. AWS introduced CloudWatch logs Infrequent Access storage class, offering less cost than the standard one. However, it seems the serverless framework still hasn't adapted the feature yet.

it would be nice to have it.
