Abstract: A versioned schema of a data platform. A process of maintaining a call stack of executing objects of an application package having a versioned schema includes calling, by a first procedure executed by one or more processors, a second procedure of a versioned application instance, and determining, by the first procedure, a version of the second procedure based on a call context. In response to determining that the version of the second procedure is not in the call context, the first procedure determines a current version of the versioned application package adds the current version to the call context as the version of the second procedure.
