Q1Domain Verified

In the context of Redis Streams and Event Sourcing, what is the primary mechanism that enables the "append-only" nature of events, ensuring immutability and chronological order?

Redis Hashes, which store key-value pairs for individual event attributes.

Redis Sorted Sets, which maintain elements in sorted order.

Redis Streams, with their internal log-like structure and sequence IDs.

Redis Sets, which provide unique element storage.

Q2Domain Verified

When implementing an event-sourced system with Redis Streams, what is the recommended approach for handling consumer group processing to ensure at-least-once delivery and fault tolerance?

Consumers within a group share a unique consumer name, and Redis tracks the last delivered message ID per consumer group and consumer, allowing for recovery.

A single, dedicated consumer within the group is responsible for reading and acknowledging all messages.

Each consumer within a group independently polls the stream for new messages, discarding duplicates.

Messages are explicitly deleted from the stream by consumers once processed to prevent redelivery.

Q3Domain Verified

Consider a scenario where an event-sourced aggregate's state needs to be reconstructed from a Redis Stream. What is the most efficient and idiomatic way to achieve this using Redis Streams commands?

Leveraging the `XREADGROUP` command to read events, and then filtering and applying them based on an aggregate ID embedded within the event data.

Iteratively using `XREAD` with a very large `COUNT` to fetch all historical events for the aggregate.

Using `XREVRANGE` to fetch events in reverse chronological order and applying them to the aggregate.

Employing `XRANGE` with a specific ID range corresponding to the aggregate's known event history, and then applying the events.
