> 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.
