DataFusion Community Showcase Vol. 4

​We're excited to present the fourth DataFusion Community Showcase!

​This virtual session will highlight two projects building on DataFusion:

​1) Tobias Schwarzinger, RDF Fusion & PolyArrow

​"Graphs, Piecewise Functions, and Apache DataFusion"

​At our reserach group we investigate the use of graph data in IoT use cases. Often, you find that you must combine knowledge about the system (which we store in graphs) with the run-time data from sensors in a single query. To enable both types of data to exist within a single query engine, RDF Fusion implements SPARQL, while PolyArrow implement querying over "piecewise signals" (i.e., instead of treating a time series as points the interpolation strategy is part of the data model). Both are prototypes based on DataFusion. I will likely talk a bit about the fundamentals, then how we build on DataFusion, some workarounds that we need to employ, and give an outlook on how we could combine these two efforts.

​2) Jérôme Schneider, Cloudflare R2 SQL

​"Building R2 SQL on DataFusion"

​R2 SQL is Cloudflare's serverless, distributed, analytics query engine for Iceberg catalogs. This talk presents how we integrate DataFusion and Datafusion Distributed over our infrastructure, and some of the challenges we faced to make it work.
