Alternatives to Pub/Sub

[Geoffrey Hoffman]

Researching building a chat system (PHP) for live help on customer's website (versus hacking into available ones such as PHP Free Chat). 

Would love to use Redis... 

Just wondering, since Pub/Sub is "eventually going away" in Redis, I have some questions:

When will pub/sub be going away? Do we know? 

How to do similar feature to pub/sub with "futureproof" code in Redis? (helpful link is this the best way?)

I read this post which linked here, and mentioned AMQP and 0MQ - has anyone seen APE-project? Node.js? WebSockets?

What are all you smart people using if not Redis Pub/Sub?

Thank you & Cheers

There's actually a really nifty way to do this. I'm going to write it
up on my blog and reply to this thread again with the link :)

I think people use XMPP.

Cheers,

Cool -  "... notice how we're not using Pub/Sub here..." Yeah, you hinted about it already... :-)

[Josiah Carlson]

That is an older blog post. I probably won't make this one into a blog
post, I don't really have time. Right now I'm commenting it so it's
understandable.

The gist for the Redis-backed chat server is:

If you have any questions, please ask :)

I just made a small update to make it properly clean up after itself.
I missed it this afternoon.

This is completely false, was never said, and I can confirm the contrary:

Pub/Sub is part of our API, we'll support it in the future forever.

Wow, I apologize for misleading any list readers!

The only place I would've gotten that idea is this list. I have to review all the the past threads on the topic now.

So then pub/sub seems a great way to implement a chat server...

[Dvir Volk]

the only feature that's being discussed as bound for deprecation  is the database numbering.

[OT]: personally I'd suggest that if you it gets cancelled, it would be possible to do DEL by pattern similar to KEYS.

not in the same command of course, not to hurt DEL's performance, maybe PDEL (pattern del)?

Maybe, but more likely Leonardo DiCaprio put this idea inside your
mind, yesterday.

No, I believe it was one of my threads. I remember this statement too.

Aha, it is Geoffrey's active imagination, after all :-)

Whew, glad to hear it!

Pub/sub might be a good way to implement a chat server if your clients
can always stay connected and always have a fast enough connection.
That's not always the case, which is why I hacked up that other
version yesterday :)

Hi Salvatore,

thanks for clearing this up, I got worried that pub/sub was going away
and was gonna write a long post on why it should still be around ....
which would have just added to the confusion and wasted everyone's
time
