>                 Key: RYA-132
>                 URL: https://issues.apache.org/jira/browse/RYA-132
>             Project: Rya
>          Issue Type: Bug
>    Affects Versions: 3.2.10
>            Reporter: Kevin Chilton
>            Assignee: Kevin Chilton
>            Priority: Minor
>
> The RyaResultsExporter is not written correctly. It assumes a single thread 
> will perform the export, which is not the case. This results in cardinality 
> values that are higher than they should be.
> The following Fluo recipe explains how to safely export from Fluo:
> https://github.com/apache/incubator-fluo-recipes/blob/master/docs/export-queue.md
> That recipe will only guarantee that a single transaction will be used to 
> write the results to to the Export Queue. However, the Exporter you write may 
> be executed on many machine concurrently, so you still may get many out of 
> order and duplicated exports. The PrecomputedJoinStorage.addResults(...) 
> method needs to be updated to handle that.
