> Currently as part of function resolution we cost all the possible function
> matches and pick the one with the best cost. However we simply pick the first
> one with the best cost, there may be a possibility that we have multiple
> functions that could have the same best cost and based on which function was
> first in the map we will execute different functions on different clusters.
> This JIRA aims to resolve functions in a deterministic way so we pick the
> same function consistently.
