Schema
CollectionSchema()
This is the constructor method to create a CollectionSchema.
Invocation
CollectionSchema(fields, description='', **kwargs)
Return
A CollectionSchema object.
Properties
| Property | Description |
|---|---|
fields | List of FieldSchema |
description | Description of the CollectionSchema |
auto_id | Boolean value that indicates if the primary keys are automatically generated |
Example
from pymilvus import CollectionSchema, FieldSchema, DataType
book_id = FieldSchema(
name="book_id",
dtype=DataType.INT64,
is_primary=True,
)
word_count = FieldSchema(
name="word_count",
dtype=DataType.INT64,
)
book_intro = FieldSchema(
name="book_intro",
dtype=DataType.FLOAT_VECTOR,
dim=2
)
schema = CollectionSchema(
fields=[book_id, word_count, book_intro],
description="Test book search"
)
FieldSchema()
This is the constructor method to create a FieldSchema.
Invocation
FieldSchema(name, dtype, description='', **kwargs)
Return
A FieldSchema object.
Properties
| Property | Description |
|---|---|
name | Name of the field |
is_primary | Boolean value that indicates if the field is the primary key field |
Example
from pymilvus import CollectionSchema, FieldSchema, DataType
book_id = FieldSchema(
name="book_id",
dtype=DataType.INT64,
is_primary=True,
)
word_count = FieldSchema(
name="word_count",
dtype=DataType.INT64,
)
book_intro = FieldSchema(
name="book_intro",
dtype=DataType.FLOAT_VECTOR,
dim=2
)
schema = CollectionSchema(
fields=[book_id, word_count, book_intro],
description="Test book search"
)
