### Description
I need to perform a bulk update in Weaviate using Python. Specifically, I have objects where a property currently has the value 0. After pre-processing, I want to update this property to 1 for multiple objects at once. How can I achieve this bulk update efficiently?

Good morning @Rushiraj_Asodariya,
Welcome to our community and it’s lovely to have you here.
Weaviate doesn’t currently support true bulk or partial updates in a single API call, each object must be updated individually by its UUID.
You have two option which both can work really great either:
- Iterate through the objects you want to update and call the update method for each one.
- Or If you use batch import for bulk update (can be faster than individual UUID) with the same UUID for each object, Weaviate will **replace** the existing objects with those UUIDs (No duplication will occur).
