You can use one of several methods to merge or combine files from Amazon S3 inside Amazon QuickSight:. Combine files by using a manifest — In this case, the files must have the same number of fields columns. The data types must match between fields in the same position in the file.
For example, the first field must have the same data type in each file. The same goes for the second field, and the third field, and so on. Amazon QuickSight takes field names from the first file. The files must be listed explicitly in the manifest.
However, they don't have to be inside the same S3 bucket. Merge files without using a manifest — To merge multiple files into one without having to list them individually in the manifest, you can use Athena.

That is useful for single files. I'll add it to our local docs.

Scanned documents are often saved as PDFs, either by default or after a conversion process. There are times when several PDFs need to be combined into a single file, such as when a long document is scanned one page at a time into six individual files.
Here are several ways to make those six PDFs turn into one document. Adobe's popular Acrobat Reader is free.

The reason I'm asking is there is a list of raw objects in S3 which we want to combine in the single object in S3. However sometimes our raw objects are not big enough and in this case when we try to complete multipart uploading we're getting famous error "Your proposed upload is smaller than the minimum allowed size" from AWS S3.
Any other idea how we could combine S3 objects without downloading them first? Keep repeating this for each fragment and finally use the range copy to strip out the 5MB garbage. Here what happens is that you first initiate the multipart upload and then upload part by part.How to concatenate multiple CSV files in one single CSV with Python

PriyajThe idea seems to be greatbut can you please help to clarify the following: By Concatenation did u mean reading the smaller chunk file stream and the garbage object and then concat and write back. Do you think there is some better way of doing that instead of reading the whole stream. Also if keep repeating the samethere were multiple chunks of garbage collection in between the concatenated file, how do I remove it from the file as the file is already written to S3 with those Garbage object.
Did u mean ready only the desired partin that case I have to maintain those ranges or a delimiter to separate that 5MBis this what you are talking about. Please suggest. So finally I implemented it, I stream all the files one by one and created temporary files of 5MB each, then using copypartObject and Multipart upload I created the consolidated files using the 5MB files in order. Hopefully, it will help someone. Hey Ankur, I am glad you figured the workaround.
It seems like a very smart approach. Can you post this as an answer as well so that its easier for other readers to understand?
