[jira] [Updated] (TINKERPOP-2886) Inconsistent results when executing equivalent queries
[ https://issues.apache.org/jira/browse/TINKERPOP-2886?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Yuancheng updated TINKERPOP-2886:
---------------------------------
Description:
{code:java}
g.V().as('s1').hasLabel('A').emit(__.loops().is(gte(1))).repeat(__.bothE().dedup().by(__.path()).otherV()).times(2).simplePath().from('s1').as('s2').hasLabel('B').emit(__.loops().is(gte(1))).repeat(__.inE().outV()).times(2).hasLabel('B').bothE().dedup().by(__.path()).otherV().hasLabel('A').select('s1').count()
// Result: 19100{code}
{code:java}
g.V().as('s1').hasLabel('A').emit(__.loops().is(gte(1))).repeat(__.bothE().dedup().by(__.path()).otherV()).times(2).simplePath().from('s1').hasLabel('B').emit(__.loops().is(gte(1))).repeat(__.inE().outV()).times(2).hasLabel('B').bothE().dedup().by(__.path()).otherV().hasLabel('A').select('s1').count()
// Result: 18198{code}
The only difference is `as('s2')`. I would not expect it to change the result. However, they output differently.
