Metadata filtering in NGT

[shriyog]

I understand that NGT doesn't support metadata filtering today. Do you have any plans (& rough timeline) to support adding metadata payload along with vectors & able to filter using it?

I agree that metadata filtering is an important feature, but there are no concrete plans for it at the moment. If there is enough demand, we will consider implementing it. If you have specific requirements or concrete use cases in mind, I’d be happy to hear them and take them into account for future implementation.
