Data Pipeline

graph8 includes a built-in customer data platform (CDP) powered by ClickHouse and PostgreSQL. Every event you send is stored, processed, and available immediately - contacts, companies, enrichment, sequences, and campaigns all work out of the box. No warehouse setup required.

Optionally, you can route a copy of your events to your own warehouse (BigQuery, Snowflake, etc.) or other tools. This is for teams that want their graph8 data alongside their other data sources.

How Data Flows

Your App (SDK / API)
    │
    ▼
  Streams (collect events)
    │
    ▼
  Functions (transform, filter, enrich)
    │
    ├──→ graph8 CDP (automatic - contacts, enrichment, sequences, campaigns)
    │
    └──→ Your warehouse (optional - BigQuery, Snowflake, Postgres, ...)
         + analytics (GA4, Amplitude, Mixpanel)
         + CRM (HubSpot)

Every g8.track(), g8.identify(), and g8.page() call automatically enters the graph8 CDP. If you’ve configured additional destinations, events are also fanned out to those simultaneously.

Streams

A stream is a data source - your website, mobile app, or server. Each stream has:

Component	Purpose
Browser key (write key)	Public key for the JavaScript SDK
Server key	Private key for server-side tracking
Domains	Allowed source domains (CORS)

When you set up graph8, a default “Website” stream is created automatically. Use the write key in your SDK init:

g8.init({ writeKey: 'YOUR_BROWSER_KEY' });

Manage streams in Connections > Sites in your graph8 dashboard.

Functions

Functions are JavaScript code that runs on every event before it reaches destinations. Use them to:

Filter out test/bot traffic
Transform event shapes to match destination schemas
Enrich events with external data (API calls, warehouse lookups)
Route events to specific tables or destinations

See the full Functions guide for API reference and code examples.

Destinations

Events are routed to all connected destinations in real-time. No extra code needed - configure once in the dashboard, every event flows automatically.

Supported destinations:

Data Warehouses

BigQuery, Snowflake, ClickHouse, Redshift, Postgres, MySQL, S3

Analytics & Marketing

Google Analytics 4, Amplitude, Mixpanel, Facebook Conversion API

CRM & Sales

HubSpot, plus any HTTP API via webhook destinations

graph8 CDP

Contacts, companies, enrichment, sequences, campaigns (automatic)

See the full Destinations guide for setup instructions.

Live Events Debugger

See events arriving in real-time. After installing the SDK, open Connections > Live Events to verify data is flowing correctly.

Filter by stream, destination, or event type
Inspect full event payloads
See function execution results
Debug destination delivery

See the Live Events guide for details.

Schema Management

graph8 automatically manages database schemas for warehouse destinations:

Auto-create tables when new event types arrive
Auto-add columns when events contain new properties
Type inference from JSON to SQL types (string, integer, timestamp, etc.)

No DDL required. Send events, graph8 handles the schema.

Replay

When you add a new destination, you can replay historical events to backfill it. All events are stored in the data lake and can be replayed with date filtering.

What graph8 Replaces

Before	After
Segment (tracking + destinations)	`g8.track()` + Connections
Clearbit (enrichment)	`g8.enrich.person()`
Outreach (sequences)	`g8.sequences.add()`
Calendly (booking)	`g8.calendar.show()`
Intercom (chat + copilot)	`g8.chat.open()` + `g8.copilot.open()`
Typeform (forms)	`g8.forms.lookup()`
HubSpot CRM	Built-in contacts, companies, lists, deals

One platform. One SDK. One bill.
