> Current FileSystem APIs include CreateFlag only for the create() api, and some of these
(SYNC_BLOCK) are for only client side and will not be stored in metadata of the file. So append()
operation will not know about these flags.
> It would be Good to support these features for append too.
> Compatibility: One more overloaded append API needs to be added to support the flags
keeping the current API as is.
