I have a number of services in a single GitHub repository, each service has its own CodePipeline on AWS managed through Terraform. Instead of triggering all of the pipelines on commit, I'd like to know how I can trigger each service's pipeline if its directory had any changes on commit, without having to split the services each into its own repository.
Trigger specific AWS Codepipeline source stage when change is made to a specific directory in repo

I don't think that there's a conditional source stage support per folder at code pipeline as we speak. Just finished checking this documentation about sources in CodePipeline. It does not seem to contain a folder-level filtering.
You could try this CDK-based template solution which showcases a mono-repository, which is composed of multiple services, have different CI/CD pipelines for each service. The solution detects which top level directory the modification happened and triggers the AWS CodePipeline configured to that directory.
This is sad but they might add it in the future. I've also wanted Quality gates, images from readme files in code-commit but these features seem too hard to implement haha.
It ended up being simpler than I had anticipated, there are github actions that do exactly what I needed.
This action checks whether a path had a change, and this action triggers a specific pipeline.
