Querying `stg_ga4__events` does not take advantage of base table partitions about dbt-ga4

[adamribaudo-velir]

I've narrowed down this issue to the following window function CTE in the stg_ga4__events model:

include_event_number as (
    select include_session_key.*,
        row_number() over(partition by session_key) as session_event_number -- Number each event within a session to help generate a uniqu event key
    from include_session_key
),

Removing this allows queries against this model (and downstream models) to only hit specific partitions when the event_date_dt field is included in the where clause. The reason we were checking for row number was to avoid duplicates, but I don't think it's worth the query cost as it's something that could be handled later downstream.

I also noticed that a join and window function in stg_ga4__event_page_view was causing that model to query all partitions. It's making me realize how careful we have to be about using window functions. Maybe they should be left to the mart models? I removed those functions in the page view model.
