Flink : FileSystems : COS FS
· This project aims to provide COS's implementation of the Flink file system interface,
so that Flink can not only use the ordinary read and write interfaces to read and write COS, but also use StreamingFileSink,
an interface that requires exactly-once semantics to write to COS.
