> What are these benchmarks?
Thanks for pointing this out. I should've added more context here. Mostafa worked on creating
a metadata benchmark by synthesizing large partitioned tables and then running some operations
that stress the Catalog. Looks like the code/scripts are not yet ready for consumption by
everyone. I borrowed those from him to run these tests. I'll add that information to the commit
message.
