Prisma multi-join query hanging on Windows 10

Bug description

I have a schema with 8 tables that all join up and I am attempting to query them all joined together, and it is hanging when I run it on my Windows machine.

On MacOS it is running in about 16 seconds. On my Windows machine it is hanging indefinitely. I put DEBUG=* logging on, but it is not super useful. No real difference in the logs between the two machines.

The database it is pulling from has about 250k records in each of the respective tables.

Setting the take parameter down to about 10,000, the query works on Windows. Much above that hangs.

How to reproduce

The steps to reproduce are roughly:

1. Clone repo: https://github.com/jakexconniff/prisma-windows-multijoin-reproduction
2. Set .env with the standard DATABASE_URL=x
3. npm install, prisma generate, prisma migrate dev
4. Run ts-node index.ts. This will populate the database with 250,000 records in each of the respective tables, with randomized data.
5. Run ts-node query.ts.

That should be it for the repro case.

On MacOS, the following works without a hitch. On WIndows, it hangs indefinitely.

Expected behavior

Query should behave as it does on MacOS. Completes with no issues in about 16 seconds each run, where it hangs on Windows 10.

I have a few other cloud databases hooked up to this project so let me run the query on those in the next few hours and I’ll follow up.

Although I do have a coworker who is able to run the query just fine on his Windows machine, targetting the same AWS RDS database I gave you access to so it must be some ambient factor but I am not positive it is (or atleast, is solely) the database.
