Yeah, with the ability to clone over something else that exists already then yeah. it's just some UX, but it makes sense. Cloudflare is more dev focused, a Scaleway has a slightly wider user base that would go to it.

Not that we're sharing yet. It will coincide with the beta. We won't be doing one-off increases.

In https://developers.cloudflare.com/workers/wrangler/configuration/#d1-databases, it says to use

(in line with kv format), but then the example uses

Adi•7/3/23, 4:12 AM

It's definitely a bit of a risk to use it right now, given it's alpha state there is a possibility for unexpected errors. That being said, from my experience D1 is mostly quite stable.
It's been said a few times before in this channel, but once backups are available for the new D1 backend, the risk for using this in production is much lower.

That would be a interesting solution. Only thing I wonder for something like d1 is say I use it to store e-commerce orders for my saas. What happens when I have over 100gb of data and ex hit the db size limits? Is there spread the data across multiple d1 databases at that point?

We dont even know what the limits of production ready D1 will be yet so we cant really give any advice for that yet

Hi Everyone. I'm new to this Discord. I am planning to use D1 for my new website. Cloudflare says they don't recommend it for production. I will have a simple interface (about 5 tables). I will be maintaining data about my clients permission to login, some client data stored as JSON strings, and some other basic stuff. Should I be concerned about the stabilithy of D1 in a production website?

U

Unsmart•7/4/23, 3:47 PM

It is an alpha product so breaking changes can happen and while it probably will work fine you probably shouldnt use it for production.

Not sure what I'm doing wrong, and I'm not experienced with JS or SQL, but
1) the console works fine
2) invalid query throw errors
but...
3) valid queries return nothing?

console.log(query);
result = context.env.db.prepare(query).bind(value);
const res = await result.raw();
console.log("RESULT: "+res);

console.log(query);
result = context.env.db.prepare(query).bind(value);
const res = await result.raw();
console.log("RESULT: "+res);

console.log(query);
result = context.env.db.prepare(query).bind(value);
const res = await result.raw();
console.log("RESULT: "+res);

console.log(query);
result = context.env.db.prepare(query).bind(value);
const res = await result.raw();
console.log("RESULT: "+res);
