@fivetran-avinash please see PR #41 for my initial review of this update.

@fivetran-joemarkiewicz New PR updates applied, in correspondence with your PR notes here.

Changes discussed that were applied.

• Modifying the source schema so that customers can pull their standard salesforce data from the history mode connector.
• Adding in logic so that all history models can load incrementally.
• Updating the folders so standard models live in salesforce, history models live in salesforce_history.
• Updating models to include a unique key.
• Updating tmp models with logic to pull from history mode with new variable.
• Eliminating all tmp history models.
• Removing superfluous history models, stashed in an additional branch.
• Creating date filters (global and model-specific) to allow customer flexibility in how much data they bring in.

I think I'm not 100% certain if my source schema setup is correct (to point to either salesforce or salesforce history), so this is what I'd recommend looking at the most in the PR re-review. Also am having some issues making the lineage line up (currently salesforce seeds are pointing toward salesforce history models. I'm wondering if I need to change my model configs).
