Florian Müller commented on CMIS-735:
-------------------------------------

There is a simple but ugly workaround for repositories that don't support append content natively:
When appendContentStream() is called, the CMIS layer fetches the current content of the document (e.g. with getContentStream()) and writes it to a temporary file. It then appends the chunk provided by the client to this file. Finally, it sets the content of this file as the new content (e.g. with setContentStream()).

Although that will get slower and slower with every chunk, there is still value for clients.
