Zuozhi Wang commented on CALCITE-4737:
--------------------------------------
I cleaned up the visulaizer and removed the TVR-related code. Here's the pull
request: https://github.com/apache/calcite/pull/2486 Reviews and suggestions
are all welcomed.
Here's a couple more issues to discuss:
1. What's a good way of including the visualizer code into VolcanoPlanner and
let developers use it easily? One way is to create the visualizer and the event
listener inside `VolcanoPlanner.findBestExp`, and introduce a variable
somewhere to turn it on/off. This visualizer might slow down optimization quite
a bit for large sized plans.
2. Where's a good place to put the frontend HTML files? The java file need to
find the HTML template. Right now they are under "core/src/main/resources".
Normal test cases under "core" project runs fine, but if it's run outside of
"core", I'm not sure if it's able to find the resource.
