 ### Known limitations
 Gateway inherits the following GCS limitations:
 
-- Maximum number of multipart parts per upload is 1024.
 - Only read-only or write-only bucket policy supported at bucket level, all other variations will return API Notimplemented error.
 - _List Multipart Uploads_ and _List Object parts_ always returns empty list. i.e Client will need to remember all the parts that it has uploaded and use it for _Complete Multipart Upload_
