What problem does this feature solve?

1 To modify or delete a piece of data in the dataset, can only the entire dataset be replaced at present?
2 If there is a large amount of data, will there be a performance problem with such frequent replacement?

What does the proposed API look like?

Are there plans to support partial updates or deletions?
