// Open a database connection db, err := leveldb.OpenFile("/path/to/db", nil) if err != nil { log.Fatal(err) } defer db.Close() // Create a new batch batch := new(leveldb.Batch) // Add several key/value pairs to the batch batch.Put([]byte("key1"), []byte("value1")) batch.Put([]byte("key2"), []byte("value2")) batch.Put([]byte("key3"), []byte("value3")) // Write the changes to the database err = db.Write(batch, nil) if err != nil { log.Fatal(err) }In this example, we open a database connection and create a new batch object. We then add several key/value pairs to the batch using the Put method. Finally, we write the changes to the database using the Write method, which ensures that all the changes are made atomically. Overall, the goleveldb package provides a robust and reliable implementation of the LevelDB database in Go, and the Batch functionality is just one example of its powerful features.
