> Project: TinkerPop 3
> Issue Type: Improvement
> Components: process

> Reporter: Matthias Broecheler
> Assignee: Marko A. Rodriguez
>
> Currently, there are two steps which retrieve properties: PropertiesStep and
> PropertyMapStep. For any vendor implementation wishing to optimize property
> retrieval this means twice the (redundant) work because each of the steps
> needs to be extended individually.
> However, the functionality is very similar. PropertyMapStep should be
> replaced by two steps: PropertiesStep which returns an iterator over
> properties and a MapAggregatorStep (not tied to the name) which consumes
> properties from the previous step and builds the map (either with property or
> values as the the map value) until the element of a property differs.
> This reuse of PropertiesStep would have increase code reuse inside TinkerPop
> and should not have a significant performance impact. Most importantly, it
> makes life a lot easier for implementors.
