(aws-core): Reuse built assets

❓ General Issue

The Question

Once I run something like cdk deploy "*" AWS CDK firstly builds all assets (e.g. Lambda Layer) with docker (if specified so), creates cdk.out directory, and lastly sequently deploys to CloudFormation.

Is there a possibility to ask AWS CDK to reuse built assets from a previous execution - something like cdk deploy "*" --reuse-assets

(I think that the. -E, --build-exclude option somehow can be used but I am not sure whether its the right one and the documentation is very minimal).

The general problem that I have is: Building lambda layers with docker (installing various dependencies, etc.) is not only time-demanding but also very memory-demanding, hence parallel stack deployments become very very very memory-demanding. If I could build assets once and reuse them in my parallel deployments I would save time and memory.

Environment

Not relevant.

No, it overrides the app definition and tells CDK to deploy the assembly directly without synth:
