Customizing Redis pubsub for message persistence – Part 2

In the last post we saw how Redis can easily be modified to persist the last published message on PubSub channels. Without subscribing to the PubSub channel we were able to get the last published message from Redis db. In this post, I will take that idea one step ahead and add native capabilities within Redis to persist all the unprocessed messages published on PubSub channel in channel specific lists. We’ll also preserve our capability to send the last published message to clients upon subscription.

Back to blogging: What to expect

I started this blog as a way to share my experiments and experiences while learning web development and computer science in general. In the first 2 years (between Apr’08 and Aug’10) I wrote as many as 100 blog posts. Quite a frenzy. Ever since, I only managed to write 5-6 posts in the following 4 years, about nearly 45 drafts which may now never get published. Good thing is that, I am back to blogging, which means a lot to share.
