Query the Statistics About a Synchronization Task with a Specified ID

Function

This API is used to query the statistics of a synchronization task with a specified ID, which includes the number of objects that are included in synchronization requests, the number of objects that are successfully synchronized, the number of objects that fail to be synchronized, the number of objects that are skipped during synchronization, and the size of objects that are successfully synchronized. Currently, this API is available only in CN North-Beijing4, CN East-Shanghai1, and CN Southwest-Guiyang1.

Calling Method
