They are end of lifing v1, which could go to zero. V2 can't. Are there any truly serverless SQL databases out there?
I use TiDB Serverless for some smaller projects I am working on.

Re: AWS cancels serverless Postgres service that scales to zero
#32I guess a good opportunity for someone to build a good alternative. Although it's hard to get it right because if you scale to 0 people will complain about latency and if you don't it's not really serverless.
There is a good alternative, https://neon.tech check them out. Really good bunch. Product is great and it's open-sourced https://github.com/neondatabase/neon
Re: AWS cancels serverless Postgres service that scales to zero
#33The term "serverless" is so confusing if to me. I had settled on "scale to zero" as my chosen definition for it, because it was the only definition that truly made sense to me and that I very strongly valued. Apparently AWS don't think it means that. I guess it just means "you'll never have to SSH in and upgrade anything"? The other thing that surprises me here is that one of AWS's biggest selling points is how rarel…

I mean if you scale to 0, you should expect cold start latency.
Re: AWS cancels serverless Postgres service that scales to zero
#35(CEO of neon.tech here) Scaling to zero is tricky. In order to make it work you need to 1. Separate storage and compute which aurora has done 2. Have a proxy between the user and an actual VM in which you host Postgres 3. Spin up this VM after authenticating a connection, stand up Postgres inside the VM and run the query You need to do all that very quickly- ideally in a couple hundred ms. This can only be accomplish…
So how does your company do it?
Re: AWS cancels serverless Postgres service that scales to zero
#36Aurora Postgres is an interesting product where AWS made significant changes to Postgres storage architecture, however it has a fairly high fixed cost. It seems in many cases RDS Postgres is cheaper and even when using Aurora, using fixed-size instance classes instead of "serverless" autoscaling classes (with ACUs) is a lot cheaper. Fixed Aurora on-demand instances are roughly 17% the cost of ACUs. Fixed instances ar…
I used to work for a business that was predominantly used by women.
Like clock work, at 3pm PS most weekdays there was a spike in traffic as our customers became active on our system.
I would love to see the real numbers behind the costs. Is time of day dependency the real price driver here? Are some customers getting more value than others out of this system?

I've never used it and it's still in beta, but I think Cloudflare D1 would qualify: https://developers.cloudflare.com/d1/
"Maximum database size 2 GB (Workers Paid) beta"
(but you can have up to 50.000 databases)
Re: AWS cancels serverless Postgres service that scales to zero
#38Reminder that AWS Aurora claims to have broken the CAP theorem. The literature doesn’t clarify whether they are consistent or available, and when you ask AWS directly, they tell you the CAP theorem isn’t relevant due to the way Aurora is built. They claim 99.99% availability or whatever the figure is, that it’s self healing, allows up to 2 replicas to be down for write availability and 3 replicas to be down for read…
Isn't Aurora similar to Googles Spanner in this regard, giving pretty much same characteristics?

Re: AWS cancels serverless Postgres service that scales to zero
#40Serverless V2 is also shit. The minimal one equivalent ACU to a regular instance has lots of latency spikes and much slower than a t3 instance. We also tried serverless Redis. We have a tiny machine at %10 CPU utilization, but sustained queries. It costs 20x more. We were very afraid of the result we just ran it for an hour to get an idea. Serverless, pay per use sounds only good if you have very few or unusual traff…
Yeah, the only systems likely to see real benefits from serverless are those with infrequent and intermittent traffic.
