---------------------------------
Summary: Rya Mongo Fail on Multi Bindingset Joins
Key: RYA-130
URL: https://issues.apache.org/jira/browse/RYA-130
Project: Rya
Issue Type: Bug
Components: dao
Affects Versions: 3.2.9
Reporter: Aaron Mihalik
Assignee: Aaron Mihalik
Rya Mongo fails on a fairly straightforward query:
{code}
DATA =
<u:a> <u:tt> <u:b> .
<u:a> <u:ww> <u:x> .
<u:a> <u:ww> <u:y> .
QUERY =
select ?s ?foo where {
?s <u:ww> ?foo .
?s <u:tt> <u:b> }
{code}
This is a bug in how Mongo Rya solves joins. The first Statement Pattern will
return multiple binding sets, and try to join it with a single statement. The
Mongo Rya Query Engine can't handle this case.
