Pipelines: Conditionally build assets on a hash #35913
Description
Describe the feature
Add a path property for assets, when if set will compute a hash of the folder contents to determine if the asset needs to be rebuilt. If the hash has not changed since last time, use the prior built asset.
Use Case
This would save a lot of processing time in the Assets step of Pipelines. The build logic would need to track the prior asset build from run to run for reuse. The hash could be used as reference.
Proposed Solution
Track the asset and hash map in a file in the common CDK S3 bucket.
