Modify Custom API to retreieve/save data from Amazon s3 to CloudFront.

Hi, I am currently uploading photos to s3 bucket and that s3 URL is being saved in the database. not since a cloudfront url is automatically generated for any object that is uploaded to your bucket, the s3 url needs to be replaced with the cloudfront url when serving the images. I want to do either option 1: it can be done either by creating another column in db for the generated cloudfront url and pulling that. or option 2: replace the s3 url in the obtained url with cloudfront url when you are pulling it from database Which I think option 2 is easier, So please I need somebody to fix that for me. thank you, regards.
