Is there a way to concatenate small files which are less than 5MBs on Amazon S3.
Multi-Part Upload is not ok because of small files.
It’s not a efficient solution to pull down all these files and do the concatenation.
So, can anybody tell me some APIs to do these?
Amazon S3 does not provide a concatenate function. It is primarily an object storage service.
You will need some process that downloads the objects, combines them, then uploads them again. The most efficient way to do this would be to download the objects in parallel, to take full advantage of available bandwidth. However, that is more complex to code.
I would recommend doing the processing on “in the cloud” to avoid having to download the objects across the Internet. Doing it on Amazon EC2 or AWS Lambda would be more efficient and less costly.
