import "github.com/cockroachdb/cockroach/pkg/roachpb" func main() { batch := &roachpb.BatchRequest{} batch.Add(&roachpb.GetRequest{ Key: []byte("mykey"), }) batch.Add(&roachpb.PutRequest{ Key: []byte("anotherkey"), Value: []byte("hello world"), }) }In this example, we create a `BatchRequest` and add two requests to it: a `GetRequest` for the key "mykey" and a `PutRequest` for the key "anotherkey" with the value "hello world". Using a batch request like this can be more efficient than making individual requests because it allows the requests to be executed atomically and in parallel, reducing the overall latency of the operation.
