> Remarks: I originally wanted to put the improvement items on cwiki to create an RFC for discussion. I found that I could not create it during the operation. I am not sure what the reason is. so create it on Jira first, then discuss, and then implement it.
>  
> To summarize the recent analysis of the implementation of TubeMQ RPC, I think we need to adjust the following content of TubeMQ RPC to make the system more powerful:
> 1. The header field of each rpc message should contain the length of the entire message, rather than the number of multiple lists, which can solve the rapid judgment of illegal messages and pre-allocate the memory resources of the message;
> 2. The message returned by the exception should not carry the exception class to the recipient of the response, but should be provided to the client through the error code and error information;
> 3. The structure of the response message of this method needs to be improved, the success field should be deleted, and errors should be distinguished by unique error codes. Use clear error codes to clearly mark specific error details so that SDK users can get the exact cause of the error and find clear error handling suggestions based on the documentation;
> 4. Each method in RPC should carry version information, so that different versions can correspond to different decoding schemes
> 5. If the subsequent RPC still uses PB for coding and decoding, you need to use maven-shade-plugin to cover PB and Netty. Otherwise, the jar package released can easily form a version conflict with the corresponding dependency package of the business
