Yun Tang commented on FLINK-25200:
----------------------------------
[~pnowojski] From my knowledge, S3 will involve copy on server side if calling
#copyObject, which cannot be really fast. And OSS would use [shallow
copy|https://issues.apache.org/jira/browse/HADOOP-15323] for normal foramt file
under 32MB or multipat format file, which could finish the copying within
hundreds of milliseconds (can achive 10 millisecond at least), which deserves
to be implemented first.
