Can you rename an unused thrift field and change its type

Question

Is it safe to rename an unused thrift field and also change its type. The APIs are still under development and not invoked by clients yet.

Answer 1

1. Yes, because you can of course change unreleased stuff as often and as much as you want.
2. Even if you published the API, renaming is generally safe, except for service and service method names. For more info, see here.
