    Description

      See Scope document for syntax. The runtimeConstants mechanism is a suggested existing implementation.

      For this ticket, we are only concerned with an implementation that works in unsharded deployments, and only for the aggregate command, and only for pipelines which don't use $merge. There is further work tracked in SERVER-46707 and SERVER-46998
