How is it generated? Is it consistent with the automatically generated id?

[CosmosNi]

Automatically generate using idea.

[hailin0]

To be compatible restore checkpoint with older versions, you should get the id automatically generated by the old version

import java.io.ObjectStreamClass;

public class SerialVersionUIDChecker {
    public static void main(String[] args) {
        long serialVersionUID = ObjectStreamClass.lookup(AmazonDynamoDBSourceSplit.class).getSerialVersionUID();
        System.out.println("serialVersionUID = " + serialVersionUID);
    }
}

ObjectStreamClass.lookup(AmazonDynamoDBSourceSplit.class).getSerialVersionUID();
This seem doesn't to work.

[hailin0]

How do you ensure that your changes remain compatible with old versions of task restore checkpoint?

[CosmosNi]

I first removed the idea generated，and I tested several, and this seems to be consistent with the one generated by idea

[hailin0]

It is recommended that you use all serialVersionUID generated by ObjectStreamClass
