stephen mallette commented on TINKERPOP-1882:
---------------------------------------------
I've often thought about a strategy like that. I guess
{{g.V(a).out().valueMap().limit(123)}} will include a {{barrier(2500)}} after
{{out()}} only to have it {{limit(123)}} later. Without the {{barrier(2500)}}
the traversal wouldn't add any extra processing that wasn't necessary, correct?
> Apply range and limit steps as early as possible

> Key: TINKERPOP-1882
> URL: https://issues.apache.org/jira/browse/TINKERPOP-1882
> Project: TinkerPop
> Issue Type: Improvement
> Components: process
> Affects Versions: 3.2.7, 3.3.1
> Reporter: Florian Hockmann
> Priority: Minor
>
> For a traversal like
> {{g.V(a).out().valueMap().limit(123)}}
> we can simply move the {{limit()}} to the left so we get:
> {{g.V(a).out().limit(123).valueMap()}}
> This avoids unnecessary database lookups.
> We should create a strategy that moves the {{limit}} and the {{range}} step
> like this to _the left_ for all {{map}} steps.
