Summary: Implement look-ahead on PathRetractionStrategy
Key: TINKERPOP-2503
URL: https://issues.apache.org/jira/browse/TINKERPOP-2503
Project: TinkerPop
Issue Type: Improvement
Components: process
Affects Versions: 3.4.9
Reporter: Stephen Mallette
With TINKERPOP-2499 we made traversal results from {{match()}} more consistent
but it came with the cost of not being as aggressive at trimming unneeded
labels. It would be good to get back to supporting patterns we once had (which
were much too strictly defined and relied on the execution of other strategies
to work) where we could properly recognize:
{code}
match(__.as("a").out("knows").as("b")).select('a')
match(__.as("a").out("knows").as("b")).dedup('a')
{code}
and perhaps even various calls to {{path()}} which has always completely exited
{{PathRetractionStrategy}}
