Why do you update the vector database only once during each batch?

Hello,

Great job on the work you've accomplished!

I noticed from the provided code that the vector database is only updated during the first iteration of each batch. However, I couldn't find an explanation for this approach in the paper. Could you please clarify the reasoning behind this decision? Thank you very much.
