[GitHub] [inlong] gosonzhang opened a new issue, #8670: [Improve][DataProxy] Define in detail the exceptions actively thrown in Source

[via GitHub]

gosonzhang opened a new issue, #8670:
URL: https://github.com/apache/inlong/issues/8670

   ### Description
   
   In DataProxy's org.apache.inlong.dataproxy.source.ServerMessageHandler 
logical processing, if an illegal exception is identified, DataProxy will throw 
an Exception[1], and the Exception will be caught in the exceptionCaught 
function of this class and perform exception statistics[2]
   
   In this logical processing, we should throw the clear exceptions with a 
clear exception class, and exclude the known exceptions of this type in the 
exceptionCaught function, so that we can only judge and analyze the 
undetermined exceptions when making exception statistics.
