An Event Processor is a software component that consumes and transforms events within event processing pipelines in event-driven architectures.
- Context:
- It can typically receive Event Notifications from event producers through event channels.
- It can typically extract Event Data from event messages for processing purposes.
- It can typically apply Transformation Logic to modify or analyze event information.
- It can typically generate Processed Events or processing results based on input events.
- It can typically handle Event Stream from multiple event sources.
- ...
- It can often implement Event Filtering to process only relevant events.
- It can often manage Event Sequencing to handle event order.
- It can often support Event Batching for processing efficiency.
- It can often provide Event Correlation to identify related events.
- It can often implement Error Recovery Strategy for processing failures.
- ...
- It can range from being a Stateful Event Processor to being a Stateless Event Processor, depending on its event processor state persistence.
- It can range from being a Simple Event Processor to being a Complex Event Processor, depending on its event processor implementation complexity.
- It can range from being a Single-Purpose Event Processor to being a Multi-Purpose Event Processor, depending on its event processor functional scope.
- It can range from being a Synchronous Event Processor to being an Asynchronous Event Processor, depending on its event processor execution model.
- ...
- It can integrate with Message Queue or Event Bus for event consumption.
- It can connect to External Systems for enrichment data.
- It can utilize Monitoring Systems for processing observability.
- It can interact with Configuration Systems for processor parameterization.

- Examples:
- Event Processor Types, such as:
- State-Based Event Processors, such as:
- Stateful Event Processor maintaining processing state across multiple events.
- Stateless Event Processor processing events independently without maintaining persistent state.
- Session-Based Event Processor maintaining session state for related event sequences.
- Processing Model-Based Event Processors, such as:
- Stream Event Processor handling continuous event streams.
- Batch Event Processor processing event batches at scheduled intervals.
- Real-Time Event Processor processing events with minimal latency.
- Domain-Specific Event Processors, such as:
- Financial Transaction Event Processor handling financial events.
- Security Alert Event Processor analyzing security events.
- IoT Data Event Processor processing device events from IoT systems.
- Implementation-Specific Event Processors, such as:
- State-Based Event Processors, such as:
- ...
- Event Processor Types, such as:
- Counter-Examples:
- Event Handler, which focuses on specific action responses to event notifications rather than event transformation.
- Data Pipeline, which processes data flows that may not be event-driven.
- Scheduled Job Processor, which executes predefined tasks on time-based schedules rather than in response to events.
- Request-Response Processor, which processes requests and returns responses in a synchronous pattern.
