It wasn't immediately clear to me that I had to bring my own database. That makes this product less appealing. I would love it if I could instrument Segment and get a redshift endpoint to query my data, but didn't have to set it up myself.
1. Self Hosted - bring your own Postgres/Redshift
2. Segment Managed - we give you a redshift endpoint (on our business tier)
The two options are described here: https://segment.com/blog/introducing-segment-warehouses-reds... and here's where you contact us regarding the hosted redshift: https://segment.com/contact/redshift
