Hello

I’ve been running some SPARQL queries on a fairly large dataset in Stardog, and I keep running into timeout issues. 😇 Even when I try to optimize the query with filters and limits, the execution sometimes stalls or gets cut off. 🙃

I’m not sure if this is purely a query optimization issue, or if there are Stardog configuration settings I should be adjusting.🤔

Has anyone here faced something similar? Are there recommended best practices for improving performance on complex joins, or should I be looking at index tuning?🤔

While exploring solutions, I came across discussions about distributed query execution and it made me think of broader concepts like [how To Build AI Agents](https://www.igmguru.com/blog/build-ai-agents-from-scratch) that can automatically suggest query improvements, which would be a game-changer in tools like Stardog.😇

I found the official [Stardog Query Optimization Guide](https://docs.stardog.com/tutorials/query-performance) that explains some tuning options, but I’d love to hear real-world tips from the community too.

Thanks in advance!

Hello,

No, usually you shouldn’t be adjusting options too much, more often it’s about adjusting the query or using query hints if it’s indeed a poorly optimised query.

I suggest to start by profiling the query to understand where it spends most of the time: [Managing Query Performance | Stardog Documentation Latest](https://docs.stardog.com/operating-stardog/database-administration/managing-query-performance#sparql-profiler)

Feel free to ask specific questions about your query or its plan.

Cheers,

Pavel
