What are the latency differences between Redis and Kafka?

What are the latency differences between Redis and Kafka?

Redis typically has lower latency compared to Kafka because it is an in-memory data store, while Kafka is designed for high throughput and durability.

Can you explain why Redis is faster?

Redis is faster because it stores data in memory, allowing for quick read and write operations, whereas Kafka writes data to disk.

How does this affect use cases for each?

For real-time applications requiring low latency, Redis is ideal. Kafka is better for event streaming and processing large volumes of data.

Are there any scenarios where Kafka might be preferred?

Yes, Kafka is preferred for scenarios involving data persistence, high throughput, and when you need to handle large streams of events.
