Sebastian Schaffert resolved MARMOTTA-80.
-----------------------------------------
Resolution: Fixed
> Improve KiWi SPARQL evaluation for certain queries
> --------------------------------------------------
>
> Key: MARMOTTA-80
> URL: https://issues.apache.org/jira/browse/MARMOTTA-80
> Project: Marmotta
> Issue Type: Task
> Components: Triple Store
> Reporter: Sebastian Schaffert
> Assignee: Sebastian Schaffert
> Fix For: 3.1-incubating
>
>
> We are currently relying completely on the in-memory evaluation of SPARQL
> queries, which is inefficient in certain cases, e.g. complex joins or simple
> queries. We should therefore implement an evaluation strategy that allows
> more efficiently evaluating certain parts of a SPARQL query, e.g.:
> - joins between triple patterns
> - certain kinds of filter joins
> - simple aggregation queries
> The rest should be based on the normal evaluation strategy offered by Sesame.
