How can I redirect with a huge list of urls?

[tuyendang-cerebral]

Say I have about 2k urls that need to redirect to new locations. My idea is create json file for mapping these urls. However, it seems like cloudfront function not support file access. I also add these mapping urls to the same file with the handler but it fails because the file is so big. What can I do now?

Consider using Lamda@Edge instead.

You are able to do that now with CloudFront KeyValueStore: https://aws.amazon.com/about-aws/whats-new/2023/11/amazon-cloudfront-keyvaluestore-globally-managed-key-value-datastore/
