There are other ways to load in Salesforce, Zendesk, or Stripe data. It is certainly nice to be able to do that all with Segment -- but it is not necessary. Sources is nice to have, but the core warehouse service is not really complete (for us, and I suspect others too) until you can seamlessly support data backfill at all price tiers. A one-time fee for backfill fee would be okay, but saying "no we don't support that" makes me sad.
Maybe you are estimating data size based on known types of data in salesforce,zendesk,etc. But what if i want to load data from my internal dB as well? The 60 day notions,etc.
So, instead of Total Company Sales this Month, I want Bob's Sales, Joe's Sales, etc. It feels like this is just a filter on top of what you already have. Almost like a parameterized query? (pass in @UserId for a where statement)
I originally thought maybe this is the job for one of your visualization partners but you really need to filter the results before you perform the aggregate.
Our salesforce source pulls in the Salesforce `Opportunities` and `Users` table (your sales team members). So to get sales by sales rep, you can join the `Opportunities` table to `Users` table, and then aggregate by sales rep.
Once you get the raw data into your data warehouse, you have a ton of flexibility with how you aggregate and analyze it.
This product release is in close partnership with our BI partners (Looker, Mode, Wagon, Periscope, BIME and Chartio). One of the biggest problems our mutual customers face is getting data into their warehouse so that they can use the BI tool in the first place. This launch significantly expands the possible audience for them.
Even better, all of our BI partners built out-of-the-box reporting and dashboards based on Segment's schemas for these new third party sources. So our mutual customers can get set up even faster.
