Configuring DynamoDB TTL

Hey folks, newb here. I’m porting a simple Rails app into Jets, and the deploy is going swimmingly. It also involves changing over from a relational DB to DynamoDB for some caching that I’d like to expire with a 30 day TTL. I know how to configure it in the AWS console or CLI, but I’m wondering if

  1. There’s a way to configure it in config/dynamodb.yml
  2. Or, barring that, being able to automatically execute a script that will do it when jets dynamodb:migrate is run
