[CMIS-904] Memory error creating large documents

• Type: Improvement
• Status: Open

• Resolution: Unresolved
• Affects Version/s: cmislib 0.5.1
• Component/s: python-cmislib

Environment

Description

I'm getting a memory error when I call Folder.createDocument(), passing a contentFile of 120MB or greater. Smaller files are uploading without trouble.

I understand from Jeff Potts that it would help if the library implemented the appendContentStream method available in CMIS 1.1.

Thanks for any suggestions!
