+
+3 members of the [Apache DataFusion] community used Rust and open source
+development to build [tpchgen-rs], a fully open TPC-H data generator over 10x
+faster than any other implementation we know of.
+
+It is now possible to create the TPC-H SF=100 dataset in 72.23 seconds (1.4
GB/s
+π) on a Macbook Air M3 with 16GB of memory, compared to the classic `dbgen`
+which takes 30 minutes<sup>1</sup> (0.05GB/sec). On the same machine, it takes
less than
+2 minutes to create all 3.6 GB of SF=100 in [Apache Parquet] format.
