In event streaming, what is the purpose of an event store?
To store real-time streams of events
What is the key function of event stream processing (ESP) engines?
Analyze and identify patterns in the stream of events
How does event streaming benefit from scalability?
Accommodate high volumes of events efficiently
What is a key advantage of event streaming in terms of replayability?
Events can be stored and replayed for debugging purposes
How does real-time processing benefit event streaming applications?
Enables minimal latency in processing events
What is the core idea behind Event-Driven Architecture (EDA)?
EDA focuses on events as the central mechanism for communication between different parts of a software system
In Event-Driven Architecture (EDA), what do event producers do?
Event producers generate events whenever something significant happens
What is one of the benefits of Event-Driven Architecture (EDA)?
Decoupled Services in EDA
What does real-time processing refer to in the context of event streaming?
Processing events as they occur, enabling real-time applications
How does event-driven architecture promote scalability?
By scaling event producers and consumers independently based on their needs
Why is loose coupling between components considered an advantage of Event-Driven Architecture?
It makes the system more modular and scalable
What is the main benefit of separating the read and write models in a CQRS architecture?
It allows for the optimization of each model for its specific tasks.
What is the main purpose of event sourcing in the context of the library analogy?
To record a complete history of all book borrowing and return events.
What is the relationship between the Librarian Area (Write Model) and the Public Catalog (Read Model) in the CQRS architecture?
The Librarian Area and Public Catalog are both optimized for the same tasks.
What is the main benefit of using event sourcing in the library analogy?
It provides a complete record of all book activity in the library.
What is the primary purpose of the Public Catalog (Read Model) in the CQRS architecture?
To provide a searchable database of books for the public to access.
What is the main trade-off or complexity associated with using event sourcing and CQRS?
They require more complex data modeling and event processing.
What is the primary role of an event streaming platform in an event-driven architecture?
To act as a central hub for storing and distributing event data
In the context of event-driven architecture, what is the role of an event producer?
To generate events and publish them to an event stream
What is the primary function of an event consumer in an event-driven architecture?
To subscribe to specific topics or categories of events and take actions based on the event data
What is the role of an event stream processing (ESP) engine in an event-driven architecture?
To continuously process the event stream, potentially filtering and transforming events
What is the purpose of an event stream in an event-driven architecture?
To store the sequence of events chronologically
What actions can event consumers take in response to receiving relevant events?
Update databases, notify other services, or trigger workflows based on the event data
Which of the following is NOT a key benefit of using event streaming platforms?
Ensuring data consistency across multiple systems
In the analogy provided, what do the cars entering the intersection represent?
Producers
Which of the following statements about event streaming platforms is NOT true?
They are designed to handle low-volume data efficiently
In the analogy, what do the traffic lights or pedestrians waiting at the intersection represent?
Consumers
What is the primary purpose of an event streaming platform?
To efficiently manage the flow of events between producers and consumers
Which of the following statements about event streaming platforms is true?
They are designed to handle high-volume data efficiently
