boto3 S3 - get last 100 modified objects in bucket without iterating through everything

My s3 bucket has many many objects (>10000), but I just need the 100 last-modified object keys. How do I get this without iterating through every object in the bucket, and then sorting using some lambda function (speed issues)?
