Request syntax
insert(
collection_name: str,
data: Union[Dict, List[Dict]],
timeout: Optional[float] = None,
partition_name: Optional[str] = "",
) -> List[Union[str, int]]
PARAMETERS:
collection_name (str) -
[REQUIRED]
The name of an existing collection.
data (dict | list[dict]) -
[REQUIRED]
The data to insert into the current collection.
The data to insert should be a dictionary that matches the schema of the current collection or a list of such dictionaries.
The following code assumes that the schema of the current collection has two fields named id and vector. The former is the primary field and the latter is a field to hold 5-dimensional vector embeddings.
# A dictionary, or data={ 'id': 0, 'vector': [ 0.6186516144460161, 0.5927442462488592, 0.848608119657156, 0.9287046808231654, -0.42215796530168403 ] } # A list of dictionaries data = [ { 'id': 1, 'vector': [ 0.37417449965222693, -0.9401784221711342, 0.9197526367693833, 0.49519396415367245, -0.558567588166478 ] }, { 'id': 2, 'vector': [ 0.46949086179692356, -0.533609076732849, -0.8344432775467099, 0.9797361846081416, 0.6294256393761057 ] } ]timeout (float | None)
The timeout duration for this operation.
Setting this to None indicates that this operation timeouts when any response arrives or any error occurs.
partition_name (string | None) -
The name of a partition in the current collection.
If specified, the data is to be inserted into the specified partition.
