Summary: Support merge API in Ozone File System
Key: HDDS-9598
URL: https://issues.apache.org/jira/browse/HDDS-9598
Project: Apache Ozone
Issue Type: New Feature
Affects Versions: 1.3.0
Reporter: Uma Maheswara Rao G
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.
