> Key: TINKERPOP-1617
> URL: https://issues.apache.org/jira/browse/TINKERPOP-1617
> Project: TinkerPop
> Issue Type: Improvement
> Components: process
> Affects Versions: 3.2.3
> Reporter: Marko A. Rodriguez
> Assignee: Marko A. Rodriguez
> Fix For: 3.2.4
>
>
> The traversal:
> {code}
> g.V().out().id().count()
> {code}
> Requires a message pass from {{out()}}. We shouldn't do this. Instead, if we
> wrap the pre-barrier stage into a {{local()}}, we have:
> {code}
> g.V().local(out().id()).count()
> {code}
> ...which doesn't require a message pass and has the same semantics. This will
> help open up numerous OLAP type traversals to single-pass/non-caching scans.
