在java中，如何在rocksDB中写入列数据？

import org.rocksdb.*;

public class RocksDBExample {
    public static void main(String[] args) {
        RocksDB.loadLibrary();

        try (final Options options = new Options().setCreateIfMissing(true);
             final RocksDB rocksDB = RocksDB.open(options, "path_to_rocksdb_directory")) {

            byte[] key = "key1".getBytes();
            byte[] value = "value1".getBytes();

            rocksDB.put(key, value);

            System.out.println("Data written to RocksDB successfully.");

        } catch (RocksDBException e) {
            System.err.println("Error writing data to RocksDB: " + e.getMessage());
        }
    }
}
