How to update only a part of the fields?

[secsilm]

For example, for the existing fields id, A, B, C, I only want to update the field A where id is 0:

client.update(collection_name, data=[{'id': 0, 'A': 'new_value'}])

Currently, Milvus only supports updating the entire row. Partial update is not supported, we have engineers working in this feature, maybe available in v2.5 or v3.0.
