Stack dataset

This is a temporary home for the Stack dataset. This dataset was first introduced with Bao, a learned query optimizer. After completing a large potion of this project at MIT before COVID. A few weeks ago, I finally got access to my lab machines again, so please be patient as I upload the data and query workloads. :)

You can download the PostgreSQL archive from these link:

• PostgreSQL 12 (as used in the Bao paper): https://www.dropbox.com/s/98u5ec6yb365913/so_pg12?dl=0
• PostgreSQL 13 (more recent version, same data): https://www.dropbox.com/s/55bxfhilcu19i33/so_pg13?dl=0

We are also making available a set of 5000+ queries that can be executed against the data. These queries are either taken from StackOverflow analytics dashboards (possibly recreated from them), or specifically generated to strain a query optimizer. These queries are made available under the terms of the MIT license.
