What are some advanced features of Redis when using it with Node.js?
Redis offers several advanced features like pub/sub messaging, Lua scripting, and transactions that enhance performance.
Can you explain how pub/sub messaging works in Redis?
Sure! Pub/sub allows messages to be sent to multiple subscribers without them needing to know about each other. You publish a message to a channel, and all subscribers to that channel receive it.
What about Lua scripting? How can it be beneficial?
Lua scripting allows you to run complex operations atomically on the server side, reducing round trips and improving performance.
Are there any specific use cases where these features shine?
Yes, for instance, pub/sub is great for real-time notifications, while Lua scripting is useful for batch processing data efficiently.
