> 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.
