Hi [~linyiqun]

Thanks for sharing your idea. The problem here is that different layers are using different
message format to transfer deletion messages, so it is not easy to define a single throttle
mechanism for all these places. You can find more details in the up-to-date [document|https://issues.apache.org/jira/secure/attachment/12886359/Asynchronous%20key%20delete%20.pdf]
I uploaded in HDFS-11922, please take a look at the document and let me know if you have any
good idea to resolve this, thanks!
