Root Cause

Lambda has 50MB zipped / 250MB unzipped deployment limit.

generic

Workarounds

  1. 88% success Use Lambda layers for shared dependencies 
    aws lambda publish-layer-version --layer-name deps --zip-file fileb://layer.zip

    Sources: https://docs.aws.amazon.com/lambda/latest/dg/chapter-layers.html

  2. 92% success Use container image packaging (up to 10GB) 
    FROM public.ecr.aws/lambda/python:3.12

    Sources: https://docs.aws.amazon.com/lambda/latest/dg/images-create.html

Dead Ends

Common approaches that don't work:

  1. Compress the package more aggressively 70% fail

    Most dependencies are already compressed efficiently

  2. Split into multiple Lambda functions 65% fail

    If the oversized component is a shared dependency, splitting does not help
