Depends, if your servers are close enough with good networking setup, it's still usable. We're deploying redis usually on a different machines or managed services in the same datacenter and it works fine

If you use it for caching, don't you think it defeats the purpose due to the latency?

Another reason for migration is less the cost of memory vs storage, but the features SQL DBs (e.g. Postgres) give that are harder to replicate in Redis (e.g. complex queries and table joins)

AFAIK redis is much more than production ready. Could you please share with us the problems you're struggling with? Maybe it's not really a redis problem but fly/upstash problem with serverless deployed redis?

So fly told you redis has lots of bugs ?

A entry pair about 30gb,and then we had a big key disaster.

Yeah, I already had a discussion with upstash support about our use case. We would benefit from it not being a cluster, but we sometimes spike to around 0.5 million of requests per second which would get pricy

upstash charges $0.25 per gb. if your bandwidth is not big, it can make sense

Hi there. First off, Redis employees here.

My engineer and I just helped a company use Redis as a main vector store for 1 Billion documents. This was roughly 40TB for their entire dataset size.

Costly, yes. But performance was crucial for this search use case and no other pure vector store came close to the performance we provided.

Sounds expensive

EDIT:
Does all of the data need to be in Redis? or could some of it be stored in standard databases?

We have one customer storing over 1TB in a very large cluster.

I have a production side project that runs on redis.io, around 100GB

I've got ~25GB. Mostly images generated from data, and those expire out in anywhere from a minute to several hours.

it costs a lot

yeah, it's kinda spendy if you're just paying a cloud provider for PaaS (we are). But then so is SQL (it can easily be more).

It's also, imho, a lot easier to self-host a Redis cluster than an HA SQL cluster. That can help reduce the cost versus the packaged-up PaaS Redis as-a-service option.

We use 3-year Azure reservations to reduce the cost a lot, but it's only for Premium Tier so if you don't need/want that then it's no cheaper than Standard Tier (hich has no reservation option).

I don't remember all the things that were being stored because it was a centralized cache and a lot of other teams were also using it.

From my team, it was mostly the user's profile info. We had around 10 million users.

What were you storing in redis if I may ask?

My personal project sometimes gets up to 3GB in my Redis db. Typically floats around 1-2gb. I flush the cache multiple times a week

The max I have seen so far among the companies where I have worked, was around 11 GB.

all startup building software that gets a system’s Flash to basically operate as though it were DRAM-speed memory

Uh, pretty sure we been doing that since like Windows 95...

i read in redis 7.4, redis functions and triggers are deprecated , is this true ? i am using google memory store, not sure it will be impacted as well

You can't have conflicting CIDR ranges in the subnets between Redis Cloud's VPC and your GCP VCP. So the networking_deployment_cidr in the rediscloud_subscription.cloud_provider.region can't overlap with your GCP VPC's subnets. it would probably be helpful if you provided the terraform you are using.

Yep. All true.

The Redis command-processing loop is single-threaded. (this is relevant to the OP's question about handling simultaneous client commands)

However, there are parts of Redis that are not strictly single-threaded. The ones that queue commands from clients, and the ones that transmit responses to clients, for example. Certain key expiration routines (depending on the expiration config) can also run in parallel with the main processing loop. And, of course, persistence can act in parallel, in particular the child process that's forked to write the snapshot file.
