insert()
This operation inserts data into the current partition.
notes
Using the partition_name parameter in the insert() method of a Collection object is equivalent to using the insert() method of a Partition object.
Request Syntax
insert(
data: List | pandas.DataFrame | Dict,
timeout: float | None
)
PARAMETERS:
data (list | dict | pandas.DataFrame) -
[REQUIRED]
The data to insert into the current collection.
The data to insert should match the schema of the current collection. You can organize your data into:
A list of columns
Each column is a list of each entity’s value in that column.
data = [ [0,1,2,3,4], # id [ # vector [0.1,0.2,-0.3,-0.4,0.5], [0.3,-0.1,-0.2,-0.6,0.7], [-0.6,-0.3,0.2,0.8,0.7], [0.6,0.2,-0.3,-0.8,0.5], [0.3,0.1,-0.2,-0.6,-0.7], ], ]
A pandas.DataFrame
You can form a data frame in any way, as demonstrated in the Example section on this page.
data = pd.DataFrame({ "id": [5,6,7,8,9], "vector": [ [0.1,0.2,-0.3,-0.4,0.5], [0.3,-0.1,-0.2,-0.6,0.7], [-0.6,-0.3,0.2,0.8,0.7], [0.6,0.2,-0.3,-0.8,0.5], [0.3,0.1,-0.2,-0.6,-0.7], ] })
A list of rows or just a row
Each row is a dictionary that represents an entity.
data = [ {"id": 10, "vector": [0.1,0.2,-0.3,-0.4,0.5]}, {"id": 11, "vector": [0.3,-0.1,-0.2,-0.6,0.7]}, {"id": 12, "vector": [-0.6,-0.3,0.2,0.8,0.7]}, {"id": 13, "vector": [0.6,0.2,-0.3,-0.8,0.5]}, {"id": 14, "vector": [0.3,0.1,-0.2,-0.6,-0.7]}, ] # or data = {"id": 15, "vector": [0.3,0.1,-0.2,-0.6,-0.7]},
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.
RETURN TYPE:
MutationResult
RETURNS:
A MutationResult object that contains the following fields:
insert_count (int)
The count of inserted entities.
primary_keys (list)
A list of primary keys for the inserted entities.
EXCEPTIONS:
A MutationResult object that contains the following fields:
insert_count (int)
The count of inserted entities.
delete_count (int)
The count of deleted entities.
upsert_count (int)
The count of upserted entities.
succ_count (int)
The count of successful executions during this operation.
succ_index (list)
A list of index numbers starting from 0, each indicating a successful operation.
err_count (int)
The count of failed executions during this operation.
err_index (list)
A list of index numbers starting from 0, each indicating a failed operation.
primary_keys (list)
A list of primary keys for the inserted entities.
timestamp (int)
The timestamp at which this operation is completed.
Examples
from pymilvus import Collection, Partition, FieldSchema, CollectionSchema, DataType
# Define collection schema
schema = CollectionSchema([
FieldSchema("film_id", DataType.INT64, is_primary=True),
FieldSchema("films", dtype=DataType.FLOAT_VECTOR, dim=2)
])
# Get an existing collection
collection = Collection("test_partition_insert", schema)
# Get an existing partition in the current collection
partition = Partition(collection, "comedy", "comedy films")
# Prepare the data to insert
data = [
[i for i in range(10)],
[[float(i) for i in range(2)] for _ in range(10)]
]
# Insert data
res = partition.insert(data)
# Return the count of inserted entities
