描述

Background

Due to the issue of idempotence, the SOFARPC retry framework cannot support retries for all exceptions. The current retry framework of SOFARPC only supports client timeout and server busy abnormal retries. It does not meet the requirements for business parties to flexibly use the RPC framework for retry.

What we hope to achieve

We can support the retry of custom exceptions, allowing users to confirm whether the exception can be retried.

研究方向
Examine the current retry mechanism in SOFARPC, particularly the exception handling logic in the client and server. Look at the existing retry triggers (timeout, server busy) and understand how to extend them to allow users to define custom exceptions that should trigger retries. The implementation likely requires changes to the retry policy configuration and the exception processing pipeline.
