How does BPM handle high-volume transactional processes?

Nodinite BPM scales to millions of transactions with efficient log storage, indexing, and search. This page explains:

• Architecture showing scalability layers from ingestion to archival
• Performance comparison matrix across different volume scenarios
• Real-world Black Friday scenario with 10M+ transactions
• Best practices for high-volume configuration
• Capacity planning guidelines

Configure log retention policies, archive historical data, and use Log Views with filters to manage high-volume processes. Monitor service performance and queue depth directly in BPM to proactively identify bottlenecks.

Quick Answer

Nodinite BPM handles millions of transactions per day through optimized architecture: fast event ingestion (10,000+ events/second), efficient indexed storage with sub-second search, intelligent caching, configurable retention with cold storage archival, and partitioned databases for horizontal scaling.

High-Volume Scalability Architecture

Scalable architecture: Ingest → Process → Store → Archive → Query at millions of events per day.

Scalable architecture: Ingest → Process → Store → Archive → Query at millions of events per day.

Performance Characteristics Comparison

Key Insight: Nodinite maintains sub-second search performance even at 100M+ events/day through intelligent indexing, caching, and query optimization.

Real-World Scenario: Black Friday E-Commerce

Business Context

Global e-commerce platform prepares for Black Friday—biggest sales day of the year.

Historical baseline (October average):

• 1.2M orders/day
• 8.5M log events/day (7.1 events per order average)
• Peak: 450 events/second (2 PM UTC)

Black Friday projection (November 24):

• 12M orders/day (10x increase)
• 85M log events/day
• Peak: 10,000 events/second (12 PM UTC, global rush)

Challenge: Ensure Nodinite BPM maintains performance during 10x volume spike without losing visibility into order processing.

Capacity Planning: 3 Months Before Black Friday

August 1 - Assessment:

1. Review current infrastructure:

   • SQL Server: 2 TB database (90 days hot storage)
   • Logging Service: Single instance, 500 events/sec capacity
   • Web Client: 50 concurrent users typical

2. Project Black Friday requirements:

   • 85M events/day = 10,000 events/sec peak
   • 20x logging service capacity needed
   • 5 TB database growth in 1 day (requires 10 TB buffer)
   • 300 concurrent users (customer service + IT ops monitoring)

3. Capacity plan:

   • Scale Logging Service to 4 instances (load balanced)
   • Upgrade SQL Server storage: Add 10 TB SSD
   • Optimize indexes on Search Fields (Order ID, Customer ID, Product ID)
   • Configure aggressive caching (last 1 hour of events in memory)
   • Pre-archive August-September data to cold storage (free up hot storage)

September 1 - Implementation:

• Deploy 4 Logging Service instances (12,000 events/sec combined capacity)
• Upgrade database to 15 TB SSD array
• Add 3 additional SQL Server read replicas for BPM queries
• Configure retention: 30 days hot (Black Friday → Christmas), then archive
• Test load: Simulate 10,000 events/sec sustained for 4 hours

October 1 - Validation:

• Load test results: 10,000 events/sec sustained ✓
• BPM query response: 1.2 seconds average (target < 2 sec) ✓
• Concurrent users: 400 simulated users (target 300) ✓
• Disk I/O: 45% utilization at peak (healthy margin) ✓

Black Friday: November 24

• Cache hit rate: 87% (excellent)

Incident: 12:43 PM - Payment Gateway Bottleneck Detected

1. BPM shows: 4,200 orders stuck in "Payment Processing" step (red)
2. Operations team: Clicks "Payment Gateway Resource" in BPM
3. Resource monitoring: Queue depth: 8,700 messages (normal: < 500)
4. Root cause identified: Payment gateway connection pool maxed at 2,000 concurrent requests
5. Remote Action executed: Scale payment gateway pool to 5,000 connections
6. Resolution: Queue drains in 8 minutes, order processing resumes
7. Total downtime: 8 minutes (vs. potential hours without BPM visibility)

6:00 PM UTC - Traffic Normalizes

• Event rate: 3,000 events/sec
• 9.2M orders processed (18 hours)
• 68M log events stored (80% of daily projection)

11:59 PM UTC - Black Friday Complete

• Final count: 11.8M orders processed
• Total log events: 83.2M events
• Peak throughput: 10,247 events/sec (successfully handled)
• Database size growth: 4.8 TB in 24 hours
• BPM availability: 100% (no outages)
• Average BPM query response: 1.4 seconds
• Payment gateway incident: 8 minutes (detected & resolved via BPM)

Performance Metrics: Black Friday vs. Normal Day

Business Impact

Revenue protected:

• Payment Gateway incident resolved in 8 minutes
• Estimated orders lost if not detected: 4,200 orders × $147 avg = $617,400 revenue at risk
• With Nodinite BPM detection: 8-minute impact = ~150 lost orders = $22,050 impact
• Revenue protected: $595,350

Operational efficiency:

• Customer service handled 28,000 inquiries during Black Friday
• Average inquiry resolution: 3.2 minutes (using BPM Search Field Links)
• Without BPM: Estimated 12 minutes per inquiry (manual log searches)
• Time saved: 8.8 minutes × 28,000 inquiries = 4,107 hours = $123,200 labor savings

Customer satisfaction:

• Order status transparency: Customers could track orders in real-time
• Proactive notifications: Email sent when orders stuck (detected via BPM alerts)
• NPS score: 87 (Black Friday) vs. 78 (typical day)—improved despite high volume

High-Volume Best Practices

1. Configure Retention Policies

Hot Storage (Fast SSD):

• Operational troubleshooting: 30-90 days
• Trade-off: Cost vs. query performance
• Recommendation: 90 days for most enterprises, 30 days during peak events (Black Friday → Christmas)

Cold Storage (Cheaper HDD/Archive):

• Compliance & audit: 1-7 years (industry-dependent)
• Query performance: Slower (acceptable for historical analysis)
• Cost: 1/10th of hot storage

Purge Policy:

• Beyond regulatory requirements: Automatic deletion
• GDPR consideration: Honor data deletion requests
• Recommendation: 7 years for financial data, 3 years for operational data

2. Use Targeted Log Views

Efficient queries:

• ✅ Filter by date range (last 7 days)
• ✅ Filter by domain (Finance department only)
• ✅ Filter by Message Types (Order Created events)
• ✅ Use Search Field Links for specific Order ID

Avoid inefficient queries:

• ❌ "Show all events" (across 90 days, millions of records)
• ❌ Wildcard searches without filters ("%payment%")
• ❌ Complex regex on full payloads (use Search Fields instead)

3. Monitor Queue Depth Proactively

Set alerts:

• Queue depth > 1,000 messages: Warning (review capacity)
• Queue depth > 5,000 messages: Critical (scale immediately)
• Processing rate < 50 events/sec: Warning (performance degradation)

Use BPM Resource Monitoring:

• Track service processing rates in real-time
• Visualize queue trends over time
• Execute Remote Actions to scale resources (add worker threads, scale out services)

4. Optimize Search Field Expressions

Efficient extraction:

• ✅ XPath: //OrderID/text() (fast, precise)
• ✅ JSONPath: $.transaction.orderId (fast, precise)
• ❌ Complex Regex: (?<=OrderID:)[\d\w-]+(?=,) (slower, CPU-intensive)

Index frequently-queried fields:

• Order ID, Customer ID, Invoice Number (business-critical)
• Correlation ID, Transaction ID (troubleshooting)
• Skip: Rarely-queried metadata (reduces index overhead)

5. Capacity Planning Formula

Estimate storage requirements:

Average event size: 5 KB (payload + metadata)
Daily events: 10M
Daily storage: 10M × 5 KB = 50 GB/day

Hot storage (90 days): 50 GB × 90 = 4.5 TB
Add 50% buffer for peak events: 4.5 TB × 1.5 = 6.75 TB
Add index overhead (30%): 6.75 TB × 1.3 = 8.8 TB total

Recommendation: Provision 10 TB SSD for hot storage

Estimate logging service capacity:

Peak events/second: 5,000
Add 50% headroom: 5,000 × 1.5 = 7,500 events/sec target

Single Logging Service instance: 2,500 events/sec
Instances required: 7,500 / 2,500 = 3 instances (load balanced)

Recommendation: Deploy 4 instances for high availability
