> Current ozone does not have flexibility to concatenating the files. We have multipart upload functionality in place and it does merging at server at the end of the upload. So, we should be able to reuse most that functionality at server to implement merge functionality.
>  
> Since Ozone semantics are like visible only after key commit, it would be good to have this merge option for file system users to create smaller files and merge. So, that they don't need to retry bugger size(say 10GB) files upload in full. They can split into smaller file and try. Once all smaller file uploads done, they can use merge functionality to create targeted file.
