SegmentStream layers cross-channel attribution and budget optimization on top of Twilio Segment — reading raw event data routed by Segment's Warehouse destinations into your data warehouse.
Twilio Segment is a customer data platform — it collects events from your sites and apps and routes them to destinations. One class of destinations is data warehouses. When Segment is configured to write to a warehouse, SegmentStream reads from that same warehouse.
Segment Warehouse destinations include BigQuery, Snowflake, Redshift, Databricks, Postgres, Azure SQL DW, and Data Lakes (AWS Glue / S3). SegmentStream connects to whichever one you use.
Segment routes raw events from your sources to destinations. SegmentStream isn't a Segment destination in the classic sense — it consumes the same raw events that Segment lands in your warehouse, then builds identity graph, cross-channel attribution, and budget optimization on top. No separate event mapping or transformation is required.
Segment writes warehouse data forward from when the destination is enabled. For replays of historical event data, see Segment's Warehouse destinations documentation — replay support varies by source and plan.
