This page overviews a design and specific suggestions for Wikidata SPARQL query testing. These tests will be useful to evaluate Blazegraph backend alternatives and to (possibly) establish a Wikidata SPARQL benchmark for the industry.


  • Definition of multiple data sets exercising the SPARQL functions and complexities seen in actual Wikidata queries, as well as extensions, federated query, and workloads
    • Definition of specific INSERT, DELETE, CONSTRUCT and SELECT queries for performance and capabilities analysis
    • Definition of read/write workloads for stress testing
    • Goal to test both system characteristics and SPARQL compliance, and behavior in real-world scenarios

Testing Wikidata-Specific Updates and Queries

Design based on insights gathered largely from the following papers:

Also, the following analyses examined more recent data:

TBD - Address different query and update patterns, including a variety of SPARQL features (such as FILTER, OPTIONAL, GROUP BY, ...), federation, geospatial analysis, support for label, GAS, sampling and MediaWiki "services", and more

Workload Testing

Combinations of above (TBD)
