In the navigation pane on the left, click Cluster List. Select the collection that contains the vectors you want to update, and click Details.
In the left-side secondary navigation pane, click Update Vector. Enter the required information and click Confirm to update the vector.
NoteIf the specified ID does not exist when you update a vector, the update operation fails.
If you update only some fields, the other fields are set to
Noneby default.
