how it works

One universal index.
No tuning.

Instead of maintaining multiple indices, Tentris stores RDF graphs in a single compressed Hypertrie that eliminates structural redundancies found in graphs to minimize memory usage.

Adaptive
query Planning

Tentris uses exact cardinalities from the Hypertrie for adaptive query planning, reducing unnecessary work and improving performance on complex graph patterns.

Worst-Case 

Optimal Joins

Tentris requires minimal RAM by evaluating queries using worst-case optimal joins. Query results are streamed and intermediate results are not materialized.
