kryo 是一个针对Java的快速,高效的二进制对象图形序列化框架。 kryo目标 kryo的目标是高速、占用空间小、并且有简单好用的api 随时为Java对象提供持久化的能力,包括持久化为文件、数据库、或者网络传输。 kryo也可以实现深度和浅度的复制,克隆。 kryo 复制的过程 这是一个对象到对象的复制,而不是对象到字节数据,...
Kryo is a fast and efficient binary object graph serialization framework for Java. The goals of the project are high speed, low size, and an easy to use API. The project is useful any time objects need to be persisted, whether to a file, database, or over the network. Kryo can also...

后续出现的同一类对象图的对象用变长的int来写(using a variable length int)。写类的名字有点低效,所以类可以事先注册:kryo.register(SomeClass.class);这样的话,SomeClass 注册到了 Kryo,它将该类与一个 int 型的 ID 相关联。当 Kryo 写出 SomeClass 的一个实例时,它会写出这个 int ID。这比写出类名更...

spark 2.0以上版本 默认org.apache.spark.serializer.KryoSerializer序列化方式。如果你使用java 序列化那么铁定跪了。所以统一spark序列化方式 要不是这 spark成java序列化方式 conf.set("spark.serializer", "org.apache.spark.serializer.JavaSerializer")
