序列化到堆内缓冲区
将数据序列化到 Java 字节数组。
Java schema 一致性序列化
反序列化端必须与序列化端使用相同的类定义。 该模式不支持类的前向/后向兼容。
Java schema 兼容模式序列化
反序列化端可以与序列化端使用不同的类定义。 该模式支持类的前向/后向兼容。
Java schema 一致性反序列化
反序列化端必须与序列化端使用相同的类定义。 该模式不支持类的前向/后向兼容。
Java schema 兼容模式反序列化
反序列化端可以与序列化端使用不同的类定义。 该模式支持类的前向/后向兼容。
堆外序列化
将数据序列化到堆外内存。

零拷贝序列化
注意：零拷贝序列化只是在序列化阶段避免拷贝；如果将数据发送到其他机器，仍可能发生拷贝。
但如果在同一节点进程间序列化并使用共享内存，且数据在序列化前已位于堆外，那么其他进程可无拷贝读取该缓冲区。
