AWS CDK and caching the cdk.out directory in build pipelines

Question

I am using BitBucket pipelines to deploy an app to AWS using the Python CDK. As part of the process the cloud assembly cdk.out directory is created as documents in the AWS docs.

I am wondering if there is any benefit in caching this directory so that it's reused between pipeline runs, just like we cache pip dependencies for example, or just let it be created from scratch on every pipeline run.

Answer 1

cdk deploy synthesizes the CloudAssembly artifacts into cdk.out each time before deploying. Caching wouldn't help there.

However, the CDK apparently caches zipped artifacts (before uploading to S3), so in theory you could save .zip-ing time by caching cdk.out/.cache.
