GROWTH PATTERN

Adding Retention to Cassandra Apps

After users sign up and start using Cassandra, there's no infrastructure to identify when they become inactive or celebrate growth milestones.

What's Missing in Standard Cassandra Architecture

While Cassandra handles data storage correctly, there's no built-in system to track user behavior patterns and identify when users become inactive. You need to implement custom activity monitoring.

Standard Cassandra Flow vs Optimized Skene Flow

Standard Flow
1

User completes onboarding

2

User activity tracked manually (if at all)

3

No automated re-engagement when activity drops

Skene Flow
1

Monitor your database 'events' table for user activity patterns via standard features

2

Detect when user becomes dormant (created 5+ records this week)

3

Trigger re-engagement email sequence with personalized content

4

Track re-engagement success and adjust campaigns

How Skene Fixes This

We created a Skene configuration that tracks user activity in your database and correlates it with authentication session data. When users become dormant, it automatically sends personalized re-engagement emails that reference their last actions.

Implementation Comparison

Using Skene Infrastructure

Install via Prompt

cursor.mdc
@task: Initialize Skene.
@action: Analyze my local code, validating subscription via `npx skene login`, and generate `skene.config.ts` to implement the Retention Loop pattern for Cassandra.

Copy Skene Prompt for Cursor

Generated skene.config.ts

skene.config.ts
// skene.config.ts - The Automated Way
import { defineLoop } from '@skene/sdk';

export default defineLoop({
  type: 'retention',
  opinion: 'Detect dormant users and trigger personalized re-engagement campaigns',
  steps: [
    {
      trigger: {
        type: 'schedule',
        cron: '0 9 * * *' // Daily at 9 AM
      },
      condition: {
        type: 'query',
        query: `SELECT * FROM users WHERE last_activity_at < NOW() - INTERVAL '7 days' AND re_engagement_sent = false`,
        timeout: '10m'
      },
      action: {
        type: 'email',
        provider: 'resend',
        template: 're_engagement',
        personalization: {
          name: '{{user.name}}',
          lastActivity: '{{user.last_activity_at}}'
        }
      }
    }
  ],
  recovery: {
    retries: 3,
    backoff: 'exponential'
  }
});
