Status on SQL API
Hi Wayang Dev!
Just a quick update on the research project involving the SQL API that Michelle and I are working on:
Due to our limited time, we are focusing on implementing:
1. The join operator (probably just the inner join)
2. Sql query from both a csv and postgres data source
We’re currently waiting for the current SQL API to be merged into the Wayang repository. Afterwards we will be happy to contribute with our work.
We have been searching for the implementation of the join operator in the java API, but we haven’t succeeded. So if any of you have a pointer to this, it would be much appreciated!
Best regards,
Michelle and Kristian!

Great!
How do you prefer the git organisation? I assume we should create a new branch from main(?). If so, is there any naming convention that we should follow or other things that we should be aware of? This is our first contribution to open source projects.

regarding your "implementation of the join operator in the java API" question, what exactly are you looking for?
Isn't there a join operator via the JavaPlanBuilder?
