Wikidata has grown in all dimensions since its start 9 years ago. In this talk we will have a look at one of the biggest technical scaling challenges that Wikidata currently faces: the Wikidata Query Service. We provide a high level overview of the technical challenges of scaling Wikidata Query Service (which were also outlined in the August 2021 update) and the current results of the WDQS user survey. Based on this, we introduce some of our current strategies/plans for scaling and how you can help make them reality.

This session provides a forum to discuss the scaling challenges of Wikimedia Query Service (WDQS), including the short term disaster mitigation and long term strategies, such as migrating to an alternative of Blazegraph.
