Finish "add joins, insertion & search to correlation engine"

[stephen-crawford]

Description

This PR is meant to help finish #7771.

Based on the existing PR it looks like this feature was close to being completed before being dropped. I am hoping to finish it by making whatever existing changes were required by the maintainers to help get it over the line.

I rebased the original change by merging it into a clean main. I am going to see what else can be done to make this ready for merge. @sbcd90 if you would like to pick this back up please let me know otherwise thank you for your efforts.
