(aws-cdk): CDK 2.79.0 size above 300 MB

[ermanno]

Describe the bug

The Python CDK 2.79.0 package is above 300 MB. From past interactions we were informed that this should have been caused by a bug introduced in 2.73.0 which would have been fixed in more current versions. This is an issue for our use case (use CDKv2 from a lambda layer, which has a 265 MB size limit).

Expected Behavior

The CDKv2 size should be around 100 MB like in versions prior to 2.73.0.

Current Behavior

The latest CDKv2 version (2.79.0)'s size is above 300 MB.

Reproduction Steps

• pip install aws-cdk-lib==2.79.0
• List the size of cdk dirs in site packages:

  (venv) ➜  site-packages du -hd1 | grep cdk
  36K    ./aws_cdk.asset_node_proxy_agent_v5-2.0.142.dist-info
  36K    ./aws_cdk.asset_awscli_v1-2.2.169.dist-info
  36K    ./aws_cdk.asset_kubectl_v20-2.1.1.dist-info
  168K    ./aws_cdk_lib-2.79.0.dist-info
  346M    ./aws_cdk

Possible Solution

No response

It's certainly a contributing factor.

We face the same problem, and I can see that the following modules are also massive, and I can't see the need for them:

29592 asset_awscli_v1 49664 asset_kubectl_v20

With quicksight, I've removed it from the import in init.py and done a rm -rf aws_quicksight, but it still leaves the aws-cdk-lib module at around 171MB - yikes.

Ideas how to remove those above?

@ermanno - did you find a solution?

[ermanno]

@tgmedia-nz Unfortunately, no. For the moment we are using an older version which didn't have this problem, but of course going forward we will need to be able to update this dependency.

Hi @pahud - sorry to raise this again but would someone be able to point into the right direction on how to remove the dependency of asset_awscli_v1 and asset_kubectl_v20?

[tgmedia-nz]

Any help please?

Just in case anyone else comes across this - we've shifted to use CDK v2 via CodeBuild where we have a ecr repo with pre-built CDK and all requirements installed, then just calling CB via event bridge.
