aws-lambda-unzip-py

Python AWS Lambda function to extract zip files uploaded to S3.

The zip file will be deleted at the end of the operation.

Permissions

To remove the uploaded zip file, the role configured in your Lambda function should have a policy similar to this:

{
    "Effect": "Allow",
    "Action": [
        "s3:GetObject",
        "s3:PutObject",
        "s3:DeleteObject"
    ],
    "Resource": [
        "arn:aws:s3:::mybucket"
    ]
}

TODO

You might know the limitations of AWS Lambda. The limitation of maximum execution duration per request could cause problems when unzipping large files, also consider the memory usage.

• Improve performance (if possible) for large files
• Extract files where the zip file was uploaded
