             Summary: Guidance about upgrading Interface Definition Files
                 Key: THRIFT-2943
                 URL: https://issues.apache.org/jira/browse/THRIFT-2943
             Project: Thrift
          Issue Type: Documentation
            Reporter: Jordan Librande
            Priority: Blocker


I have an existing thrift service with consumers. I want to upgrade the interface file to a newer version. I haven't been able to find any resources talking about this process in depth.

Some of the questions I have:
Can struct/exception definitions ever be removed?
Can structs/exceptions be renamed?
What's the process for changing what arguments a function can take?
What's the process for changing the list of exceptions a function can throw?
What's the process for changing the return type of a function?

Is there existing documentation to help me answer these questions? I'd also love to see some examples of real interfaces and how they've changed over time.
