```
cl, err := pulsar.NewClient(pulsar.ClientOptions{
URL: url,
OperationTimeout: 10 * time.Second,
ConnectionTimeout: 10 * time.Second,
})
cl.Close()
reader, err := cl.CreateReader(pulsar.ReaderOptions{
Topic: topic,
StartMessageID: pulsar.LatestMessageID(),
StartMessageIDInclusive: true,
})
for reader.HasNext() {
msg, err := reader.Next(context.Background())
}()
```
