Assume we have a collection with 2 fields(one primary key and one vector field) and 5 rows:

There are two ways to represent the collection with data files:

(1) Row-based data file, a JSON file contains multiple rows.

file_1.json:

{  
  {"uid": 101, "vector": [1.1, 1.2, 1.3, 1.4]},  
  {"uid": 102, "vector": [2.1, 2.2, 2.3, 2.4]},  
  {"uid": 103, "vector": [3.1, 3.2, 3.3, 3.4]},  
  {"uid": 104, "vector": [4.1, 4.2, 4.3, 4.4]},  
  {"uid": 105, "vector": [5.1, 5.2, 5.3, 5.4]},
}

...

import(collection_name="test", files={"uid": "file_1.json", "vector": "file_2.json"})

We also allow user to store vectors in a Numpy file, let's say the "vector" field is stored in file_2.npy, then we can call import():
