New views in data shares to simplify Usage Group queries

Previously, when writing a query against our data shares involving Usage Groups, the full Usage Group definition would be present in the query leading to increased query complexity and damaging readability.

with
select
    start_day as day,
    sum_query_cost
from (
    select
        start_day as day,
        -- full usage group definition included
        case
            when warehouse_name in ('DBT_S', 'DBT_M') or user_name in ('SVC_DBT') then 'Analytics Engineering'
            when warehouse_name in ('Warehouse 1', 'Warehouse 2') or user_role in ('MARKETING_ANALYST') or database_name in ('MARKETING') then 'Marketing Team'
            when ...
            when ... 
            else 'Uncategorized'
        end as usage_group,
        sum(sum_query_cost) as sum_query_cost
    from select_datashare.transformed.daily_workloads_usage_groups
    where
        start_day >= '2024-09-01'
        and start_day <= '2024-09-14'
    group by all
)
where
    usage_group in ('Marketing Team')
order by day desc nulls last

We've since created new views, which abstract away the Usage Group definition leading to simpler queries.

select
    start_day as day,
    sum(sum_query_cost) as sum_query_cost
from select_datashare.transformed.daily_workloads_usage_groups
where
    usage_group in ('Marketing Team')
    and start_day >= '2024-09-01'
    and start_day <= '2024-09-14'
group by all
order by day desc nulls last
