Prerequisite Checklist

blocking

team

Team at 'experienced backend team' maturity level

This scenario is rated 'experienced backend team' complexity. Engineers with 2+ years of production backend experience, including database tuning and monitoring.

Gap signal: Team frequently reaches for external help during incidents or struggles to debug multi-system issues independently.

blocking

process

Failure mode awareness and runbooks

The team must understand the 1 documented failure modes for this scenario: replication_lag_cascade. Each should have a documented detection procedure and runbook.

Gap signal: The team has no documented runbooks for the scenario's failure modes or cannot name them without reference material.

blocking

monitoring

Production-grade observability stack

The scenario requires real-time metrics, structured logging, and distributed tracing on all critical components. Alerting must be configured before going live.

Gap signal: No dashboards exist for the critical path metrics in the scenario.

infrastructure

Minimum team maturity: Experienced Backend Team

This scenario has high operational complexity. It is recommended for Experienced Backend Team teams or higher.

Gap signal: The requirement 'Minimum team maturity: Experienced Backend Team' is not yet in place.

infrastructure

Event stream operations expertise

This architecture includes event stream infrastructure (Kafka, Kinesis, or similar). Operations requires consumer group management, partition assignment, dead-letter handling, and lag monitoring.

Gap signal: The requirement 'Event stream operations expertise' is not yet in place.

blocking

infrastructure

Apache Kafka: scenario uses Kafka for event streaming or CDC

Set min.insync.replicas=2 with acks=all; monitor consumer lag as primary health signal

Gap signal: The requirement 'Apache Kafka: scenario uses Kafka for event streaming or CDC' is not yet in place.

Infrastructure Requirements

Apache Kafka

high burden

Distributed event streaming platform designed for high-throughput, fault-tolerant, ordered, and durable log-based messaging between producers and cons

Managed: Amazon MSK (Managed Streaming for Kafka), Confluent Cloud, Azure Event Hubs (Kafka-compatible), Redpanda Cloud

PostgreSQL

medium burden

ACID-compliant relational database with strong consistency, JSONB support, full-text search, and mature replication.

Managed: Amazon RDS for PostgreSQL, Amazon Aurora PostgreSQL, Google Cloud SQL for PostgreSQL, Azure Database for PostgreSQL, Supabase, Neon

Observability Requirements

pg_replication_slots shows growing pg_wal_lsn delta for CDC slot; PostgreSQL WAL directory growing faster than expected

This signal indicates the architecture is approaching 'Tier 1: CDC Slot Lag'. Likely bottleneck: Debezium / CDC connector not keeping up with write volume.

Tier 1: CDC Slot Lag

Kafka consumer group lag growing; analytics dashboards increasingly stale; consumer CPU and network I/O near ceiling

This signal indicates the architecture is approaching 'Tier 2: Kafka Consumer Lag'. Likely bottleneck: Insufficient consumer parallelism or insufficient Kafka partitions.

Tier 2: Kafka Consumer Lag

Analytics consumers failing deserialization; event count drops for specific topics; schema registry (if in use) reports

This signal indicates the architecture is approaching 'Tier 3: Schema Evolution Crisis'. Likely bottleneck: Unmanaged DDL changes breaking Avro or JSON schema contracts.

Tier 3: Schema Evolution Crisis
