### Before Creating the Enhancement Request - [X] I have confirmed that this should be classified as an enhancement rather than a bug/feature. ### Summary Fixed asynchronous send backpressure capability ### Motivation The semaphore should be released after sending the callback. Otherwise, it will not have the effect of back pressure. ### Describe the Solution You'd Like Release the semaphore in sendCallBack ### Describe Alternatives You've Considered After turning on backpressure, it can be sent asynchronously at the expected rate limit. ### Additional Context _No response_ -- This is an automated message from the Apache Git Service.
