Trino2Trino connector about trino

I'm still determining if this will be helpful, but I've been given the go-ahead to open-source the basic trino-to-trino connector my team developed for a research project.

The code has been made available here. Apologies that it's a fresh repo with a little history—we have an internal mono repo for custom Trino plugins, and this code was pulled out of there. It was written by DevOps, who mainly work in Python/Go/C++/Rust and have limited knowledge of Java, so if there's anything egregious, it's because we didn't know any better!

We're currently working on implementing pushdown and fixing the presently broken tests. I hope that the code will be a helpful starting point for a PR.

@alee-x thats awesome .. we are currently working on getting a more mature one from another group approved for sending a PR. The idea would be that we get the other version merged and then you and all others who have their own version can contribute specific improvements. That should result in a good connector for everyone to use and it will safe everyone the rebasing, and all other related work with maintaining a fork.
