Looks good, thanks, will merge this.
I would suggest two followups:
- We can remove the "dispose savepoint" method, because that is
functionality disappearing right now. Savepoints need no special remove logic
any more, they are just a directory in a filesystem.
- We can reduce the number of message classes (like
`TriggerSavepointResponse`) by using exceptions more prominently. The
"triggerSavepoint()" method could simply return a String (success) or throw an
exception (failure). Exceptions are propagated by the RPC, so the caller future
will always get it as a response.
