             Summary: Consider Required TraversalStrategies
                 Key: TINKERPOP3-669
                 URL: https://issues.apache.org/jira/browse/TINKERPOP3-669
             Project: TinkerPop 3
          Issue Type: Improvement
          Components: process
            Reporter: stephen mallette
            Priority: Minor


As we now execute the Gremln process suite with and without strategies applied, 
it became apparent that some strategies are simply "required".  See:

https://github.com/apache/incubator-tinkerpop/blob/0d239c05638269e6cd5c7af7bd3c61a50627d0bc/tinkergraph-gremlin/src/test/java/org/apache/tinkerpop/gremlin/tinkergraph/process/TinkerGraphNoStrategyComputerProvider.java#L41-L46

https://github.com/apache/incubator-tinkerpop/blob/0d239c05638269e6cd5c7af7bd3c61a50627d0bc/tinkergraph-gremlin/src/test/java/org/apache/tinkerpop/gremlin/tinkergraph/process/TinkerGraphNoStrategyProvider.java#L42

Not sure what this means in the grand scheme of things. A few things that feel 
weird or require more thought:

1. Kinda weird that a {{Traversal}} requires any strategies at all to execute.
2. Kinda weird that a {{Step}} should know anything about strategies as is the 
case with {{ConjunctionStrategy}} for example.
3. If required strategies are expected then should those required strategies be 
somewhere more prominently maintained/documented/etc than just being relegated 
to the test suite

Not sure anything really needs to change here, just wanted to create an issue 
for future thought.
