Example

Demonstrates HasPartition() usage.

go

import (
	"context"
	"fmt"

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

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

milvusAddr := "YOUR_CLUSTER_ENDPOINT"

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

defer cli.Close(ctx)
result, err := cli.HasPartition(ctx, milvusclient.NewHasPartitionOption("quick_setup", "partitionA"))
if err != nil {
	// handle error
}

fmt.Println(result)
