A Collection instance represents collection metadata in Milvus, including the collection schema and consistency settings. Returned by DescribeCollection().

go
type Collection struct {
    ID int64
    Name string
    Schema *Schema
    PhysicalChannels []string
    VirtualChannels []string
    Loaded bool
    ConsistencyLevel ConsistencyLevel
    ShardNum int32
    Properties map[string]string
    UpdateTimestamp uint64
}

FIELDS:

ID (int64) -

The unique identifier of the collection.
Name (string) -

The name of the collection.
Schema (Schema) -

The collection schema, with field definitions and the primary key.
PhysicalChannels ([]string) -

The physical message channels the collection uses.
VirtualChannels ([]string) -

The virtual message channels the collection uses.
Loaded (bool) -

Whether the collection is currently loaded.
ConsistencyLevel (ConsistencyLevel) -

The consistency level of the collection.

Example

Demonstrates Collection usage.

go
import (
	"context"

	"github.com/milvus-io/milvus/client/v3/milvusclient"
)

ctx, cancel := context.WithCancel(context.Background())
defer cancel()

cli, err := milvusclient.New(ctx, &milvusclient.ClientConfig{
	Address: "YOUR_CLUSTER_ENDPOINT",
})
if err != nil {
	// handle error
}
defer cli.Close(ctx)

collection, err := cli.DescribeCollection(ctx, milvusclient.NewDescribeCollectionOption("books"))
if err != nil {
	// handle error
}
fmt.Println(collection.Name, collection.ConsistencyLevel)
