Versioning

Tourbillon guarantees your code will run on the same revision, even when subsequent changes are made.

Tourbillon pulls your durable executions directly from source control (i.e. git). When a durable execution is triggered, the git revision of the code that is executed is stored against the instance of the execution.

If the execution is suspended, for example; the execution sleeps for one year, upon resumption the revision will be checked out from the repository and execution will resume.

If you need to specify a revision for a given durable execution you can do so via the request headers. Omitting this header will default to the newest revision that has been pulled by the Tourbillon service.
