Introduction to Keystone CDP

Keystone is a high-performance Customer Data Platform engineered specifically for handling aggressive data ingestion loops and unified cross-channel attribution.

Core Architectural Philosophies

Keystone was built to process extreme scale without schema lock-in.

  • Schemaless Ingestion (JSONB): Data structures are volatile. We use PostgreSQL JSONB alongside dynamic schema enforcers, not rigid columns.
  • Probabilistic vs Deterministic Resolution: Not all connections are certain. Keystone uses an Anchor/Shadow model for identity merging. Shadow profiles coalesce under Anchors deterministically when identities solidify.
  • Micro-batch Optimization: Relying on arq/Redis queues, we process background enrichment without blocking API threads.

Security Overview

The entire API is secured via robust cryptographic headers:

{
  "X-API-Key": "YOUR_SECRET_KEY"
}
