问题 A user uploads multiple files into my S3 bucket with the current day as prefix for all the files. I need to trigger a lambda function only after I have received all the files under the prefix. How can I do that?. 回答1: Create a DynamoDb table to keep track of the uploaded parts. You should use a HASH key to store the prefix of the files, or something like that. Another attribute could be a count of parts. On each part uploaded, a lambda will be called and it will update the record at the table

Does this mean that aws:SourceVpc condition key is present in the request context when interacting with S3 over web console as well? My assumption is that it is present in

问题 Does anybody have a solution to sync a bucket between 2 different s3 providers? For example one is Amazon S3, second is Wasabi S3? That involves 2 different endpoints and 2 different sets of credentials. Preferable without storage data locally first, talking about 1+ million files. 回答1: This would not be possible. In Amazon S3, it is possible to copy directly between two buckets, even in different regions, because the S3 services in each region communicate with each other. This wouldn't be
