Benchmarks for Many-to-Many Joins

[Dhruv Kumar <dh...@umn.edu.INVALID>]

Hi

I wanted to ask if anyone knows any datasets or benchmarks which I can use for evaluating many-to-many joins (as depicted in the attached snapshot). I looked at TPC-H <http://tpc.org/tpch/> and TPC-DS <http://www.tpc.org/tpcds/> benchmarks but surprisingly, they mostly have one-to-many joins and I could not get much help there.





Thanks
Dhruv

Hi Dhruv,

One option is the  join order benchmark
<https://github.com/gregrahn/join-order-benchmark>  ; it has become very
popular in DB research over the past couple years and features many-many
joins. Another option is crafting many-many queries from graph datasets like
social media or travel networks.
