batch := db.NewBatch() batch.Put("key1", "value1") batch.Put("key2", "value2") batch.Put("key3", "value3") err := db.RunBatch(batch) if err != nil { log.Fatal(err) }In the above example, a new batch is created using the `NewBatch()` method. Three Put requests are added to the batch using the `Put()` method with key-value pairs. The `RunBatch()` method is then called to execute the batch in a single round-trip to the server. If there is an error, it is logged and the program exits. By using the `Batch` operation, the three Put requests are executed in a single round-trip to the server, reducing network overhead and improving performance.
