App, Web, IoT device send realtime events to a fluentd system with many events going to Segment. Web front end also loads Segment for various ad trackers. IoT device also uploads telemetry and other logs in both realtime and asynchronously and those end up in some Postgres databases. Segment syncs our event data periodically to our data warehouse (Redshift). We have a readonly replica of the eCommerce DB for live stats (Postgres). And there is a time series db for system/IoT telemetry (InfluxDB). Most of our BI queries are done in Mode. Some are done in Grafana (data in our InfluxDB and some live data). Spot check against Google Analytics or FB ad tracker...
