Again: Redis is a database, not just a cache - it doesn’t care if you store ephemeral cache artifacts or customer records within it. Redis doesn’t pose any constraints on the type of data. Inversely, you can use Postgres as a semi or full

I don’t really care about the OS. I want a beefy laptop with a good keyboard and trackpad, long battery life, and a crisp screen. Preferably very silent, bonus points for a clean design. That’s the value proposition of a MacBook.

And I'd still question it. The experience of just… knowing how a good architecture looks like without being able to really put it in words is what makes a good engineer to me. These people can pick up relevant regulations or industry t

First up, if I wanted to talk to a machine, I would've asked one myself. Then, I don't understand your point really: Yes, the CAP theorem is a thing. There are compromise solutions available however to enable highly available da

At which scale would you recommend this over a Sentinel setup?

by 9dev 4mo ago
These two concerns are not mutually exclusive, the kind of database or data stored within it doesn't give any availability guarantees on its own. Even a single Postgres instance, which I suppose fits your understanding of a real datab

Why would you even want to use that dumpster fire of a model in the first place..?

"allowing to enter the country" and "accepting" are two very distinct things.

and as you've just confirmed... there is a need for good HA support in Redis. Which was the entire premise of this thread.

by 9dev 4mo ago
This discussion is a bit weird. We started off from, Redis should have better availability guarantees. Specifically to avoid the degradation of service you described. But that requires running on multiple instances, which in turn requires t

That’s the precise point I’m making

Redis is a real database. If I wasn’t convinced it could retain data I hand it, I wouldn’t use it in the first place. Just because it works for your use case right now doesn’t mean there isn’t room for improvements to support others too.

What kind of an answer is that? This software is perfect the way it is, you’re just to inept to hold it right? A high availability protocol should not leak into the client. It should be able to discover other nodes. It should not land in

Sure the data is lost. A session commonly holds arbitrary state, and even if it’s just the login information. This is ridiculous.
348.
by 9dev 4mo ago
That you do. Until you realise that there is only a single writer in that scenario, it doesn’t address any sharding concerns, you need to use compatible clients that opt into the sentinel protocol, during failover you’ll see client errors…

It’s not. Imagine a web app that stores your user information in a session store, mapped by your cookie-provided session ID. Your web app searches redis 1 for the session id, but since that key is on redis 2, the lookup fails and the applic

Redis doesn't necessarily have to be used as a cache. Streams, for example, make it a great message queue; but a single-node message queue is a single point of failure and thus not viable for many setups.

While I love Redis as a versatile tool for external data structures, it's still lacking in two areas IMHO: One, it would be cool to be able to embed it, similar to sqlite, directly into applications. Two, the HA story is so much more c

I'm not arguing with that, I think; I agree with your general sentiment and apparently read many of the same books you read as well. Yet I still believe there's value in a shared understanding of what quality software is, and what

I like the general concept of software that treats its users as responsible adults, in the sense of not restricting them in how they can use the software; the analogy to machines that must work in remote areas with an extreme climate and no

The perspective. From within the simulation there is no point in making the distinction, but from the outside it does. For another example - running a program on a virtual machine or a physical computer is the same to the program, but very

I feel like systemd units could need a layer of abstraction above them, so instead of editing the files manually, a tool would do it, some kind of declarative CLI or something. Probably not really a concern in the age of LLMs anymore, but i

I’m not sure this is the answer. As you say, the concept of keeping the masses occupied is a lot older than TikTok or Doordash…

> a community online where AI isnt allowed. This is something I think about a lot, especially how one could pull it off without tearing down anonymity online. Having some sort of "proof of humanity" is a hard problem to solve.
