@Xuanwo Any updates on this? I can't use OpenDAL until this is fix.

Thank you for your patience. Exposing our current writer directly to Python would lead to numerous user-level problems. Therefore, we are diligently working on refactoring the Writer to enhance this feature.

Personally, I anticipate completing the refactor in our upcoming v0.40 release and commencing work on the Python side in v0.41.
