Event Driven Fundamentals

Event Producer Patterns

Charleston event producers emit business events when state changes occur including order placement, inventory updates, or user actions without knowing consumers. Patterns include event schemas, publishing guarantees, and idempotency keys that ensure reliability while maintaining decoupling through standardized event production.

Event Consumer Design

Reactive Charleston consumers subscribe to relevant events processing them asynchronously through handlers that update state, trigger workflows, or notify users. Design includes subscription management, error handling, and processing guarantees that ensure correctness while enabling scale through independent event consumption.

Event Store Implementation

Persistent Charleston architectures store events immutably creating audit trails and enabling replay for debugging, recovery, or temporal queries. Implementation includes event ordering, partitioning strategies, and retention policies that preserve history while managing storage through efficient event persistence.

Event Router Architecture

Intelligent Charleston routing directs events to appropriate consumers based on content, metadata, or routing rules enabling flexible event distribution. Architecture includes topic design, content based routing, and dead letter handling that ensure delivery while maintaining flexibility through sophisticated routing mechanisms.

Messaging Patterns

Publish Subscribe Model

Decoupled Charleston systems implement pub sub patterns where producers publish to topics and multiple consumers subscribe independently enabling fan out scenarios. Model includes topic hierarchies, subscription filters, and delivery guarantees that scale communication while maintaining independence through publish subscribe architectures.

Message Queue Patterns

Work Charleston distribution uses message queues ensuring exactly once processing through visibility timeouts, acknowledgments, and retry mechanisms. Patterns include priority queues, delay queues, and batch processing that balance load while ensuring reliability through queue based work distribution.

Request Reply Correlation

Synchronous Charleston patterns implement request reply over async infrastructure using correlation IDs and reply to addresses maintaining compatibility. Correlation includes timeout handling, response aggregation, and error propagation that enable synchronous semantics while leveraging async benefits through correlation patterns.

Saga Orchestration

Distributed Charleston transactions implement saga patterns coordinating multi step processes through events maintaining consistency without distributed locks. Orchestration includes compensating transactions, state machines, and timeout handling that ensure completion while avoiding complexity through saga based coordination.

Event Streaming Platforms

Apache Kafka Architecture

High throughput Charleston systems leverage Kafka processing millions of events per second with durability, ordering, and exactly once semantics. Architecture includes partition strategies, consumer groups, and stream processing that handle volume while ensuring reliability through Kafka's distributed log architecture.

AWS Kinesis Integration

Cloud native Charleston streaming uses Kinesis Data Streams for real time ingestion with automatic scaling and managed infrastructure. Integration includes shard management, enhanced fan out, and analytics applications that simplify operations while leveraging cloud capabilities through managed streaming services.

Redis Streams Usage

Lightweight Charleston streaming implements Redis Streams for low latency event distribution with consumer groups and message acknowledgment. Usage includes stream trimming, consumer lag monitoring, and persistence options that provide speed while maintaining durability through Redis streaming features.

Cloud Pub/Sub Services

serverless architecture Charleston architectures utilize cloud pub/sub services like SNS/SQS or Google Pub/Sub eliminating infrastructure management completely. Services include topic filtering, dead letter queues, and cross region replication that ensure delivery while minimizing operations through managed messaging platforms.

Event Processing Patterns

Stream Processing Pipelines

Real time Charleston analytics process event streams continuously using Apache Flink or Spark Streaming calculating aggregates, detecting patterns, and triggering alerts. Pipelines include windowing functions, state management, and exactly once processing that derive insights while maintaining accuracy through stream processing frameworks.

Complex Event Processing

Pattern Charleston detection identifies complex scenarios across multiple events like fraud patterns, system anomalies, or business opportunities in real time. Processing includes temporal operators, pattern matching, and rule engines that detect conditions while enabling response through CEP capabilities.

Event Enrichment Strategies

Enhanced Charleston events augment raw data with context from databases, APIs, or caches creating rich events for downstream processing. Strategies include lookup tables, caching layers, and async enrichment that add value while maintaining performance through efficient enrichment patterns.

Event Transformation Flows

Normalized Charleston processing transforms events between formats, schemas, or domains enabling system integration without tight coupling. Flows include schema registry integration, format conversion, and validation that ensure compatibility while maintaining flexibility through transformation pipelines.

Reliability and Resilience

Delivery Guarantees

Reliable Charleston messaging implements at least once or exactly once delivery using acknowledgments, idempotency, and deduplication ensuring no message loss. Guarantees include producer confirmations, consumer acknowledgments, and duplicate detection that ensure delivery while preventing duplication through reliability mechanisms.

Error Handling Patterns

Resilient Charleston systems handle failures through retry queues, dead letter topics, and circuit breakers preventing cascade failures. Patterns include exponential backoff, poison message handling, and manual intervention that recover gracefully while maintaining stability through comprehensive error management.

Backpressure Management

Scaled Charleston architectures implement backpressure preventing consumer overload through rate limiting, buffer management, and dynamic scaling. Management includes flow control, credit based systems, and elastic consumers that handle spikes while preventing failure through backpressure mechanisms.

Disaster Recovery Design

Protected Charleston systems replicate events across regions, maintain event stores, and implement replay capabilities ensuring business continuity. Design includes multi region replication, backup strategies, and recovery procedures that ensure availability while minimizing data loss through DR planning.

Integration Patterns

Legacy System Integration

Bridged Charleston architectures connect legacy systems using change data capture, polling adapters, or API gateways emitting events from traditional applications. Integration includes anti corruption layers, event translation, and gradual migration that modernize incrementally while preserving functionality through integration adapters.

Decoupled Charleston microservices communicate through events rather than synchronous calls improving resilience and enabling independent deployment. Communication includes event contracts, schema evolution, and service discovery that maintain autonomy while enabling integration through event based communication.

External System Webhooks

Connected Charleston systems receive webhooks from external services converting them to internal events for consistent processing. Webhooks include validation, transformation, and retry handling that integrate reliably while maintaining security through webhook adapter patterns.

API to Event Bridges

Hybrid Charleston architectures expose event streams through REST or GraphQL APIs enabling synchronous clients to benefit from event driven backends. Bridges include subscription APIs, long polling, and WebSocket upgrades that provide compatibility while leveraging events through API adaptation layers.

Monitoring and Observability
