Complex Event Patterns

The Retry Cascade

Understanding retry behavior:

Initial Attempt → Fail → Retry Pattern:

Attempt 1 (0s):
  - 90% success
  - 10% fail
  
Attempt 2 (+30s):
  - 70% of failures succeed
  - 30% fail again
  
Attempt 3 (+90s):
  - 40% of remaining succeed
  - 60% permanent failure
  
Optimization:
  - 3 attempts optimal
  - Diminishing returns after
  - Different delays by error type

The Quality Funnel

Track lead quality through events:

Quality Degradation Pattern:

Source Quality:
  Hour 0-1: 95% valid data
  Hour 1-2: 93% valid
  Hour 2-4: 90% valid
  Hour 4-8: 85% valid
  Hour 8+: 80% valid
  
Action:
  - Prioritize fresh leads
  - Price by age
  - Set age limits

The Feedback Loop

How feedback affects future events:

Feedback Impact Chain:

High Returns from Source X
    ↓
Tighten acceptance criteria
    ↓
More source.rejected events
    ↓
Higher quality accepted leads
    ↓
Better delivery rates
    ↓
Higher buyer satisfaction
    ↓
Premium pricing unlocked

Event-Driven Workflows

Automated Quality Management

React to event patterns:

Quality Automation Rules:

IF source rejection rate > 30% for 1 hour:
  → Notify source manager
  → Reduce volume cap by 50%
  → Require manual review
  
IF buyer timeout rate > 10%:
  → Increase timeout threshold
  → Alert buyer technical contact
  → Route to backup buyer
  
IF conversion feedback > 15%:
  → Increase source cap
  → Upgrade to premium tier
  → Request more volume

Dynamic Routing

Event-based decisions:

Smart Routing Logic:

Check Recent Events:
  - Buyer A: 5 timeouts in last hour
  - Buyer B: All successful
  - Buyer C: Returning many leads
  
Routing Decision:
  - Skip Buyer A (temporary issue)
  - Prioritize Buyer B (performing well)
  - Reduce to Buyer C (quality concerns)

Predictive Patterns

Use events to predict outcomes:

Conversion Prediction Model:

Event Signals:
  - Fast acceptance (<100ms) → +20% conversion
  - Multiple enhancements → +15% conversion  
  - Delivered in <1s → +10% conversion
  - Previous feedback positive → +25% conversion
  
Routing Strategy:
  Score > 80% → Premium exclusive buyer
  Score 60-80% → Standard buyer pool
  Score < 60% → Budget buyers only

Performance Optimization

Event Processing Speed

Handle high-volume events:

Performance Benchmarks:

Event Capture: < 10ms
Event Storage: < 50ms
Event Query: < 100ms
Aggregation: < 500ms

At Scale (1M events/hour):
  - Capture: Distributed queue
  - Storage: Time-series DB
  - Query: Indexed lookups
  - Aggregation: Pre-computed

Storage Strategies

Optimize event retention:

Tiered Storage:
