It really depends on your access patterns. If you are trying to read the same KV pair repeatedly, in the same location, KV is likely going to be faster. The trade-off is that (naturally) you need to fit into a KV-type data model.

Hello, is there a newer d1 api? Im trying to access my d1 db from my sveltekit cloudflare pages project but the only api i can find seems to be a little dated? https://www.npmjs.com/package/@cloudflare/d1?activeTab=readme

npm

@cloudflare/d1

The D1 Client API supports:. Latest version: 1.4.1, last published: a year ago. Start using @cloudflare/d1 in your project by running

npm i @cloudflare/d1

npm i @cloudflare/d1

npm i @cloudflare/d1

npm i @cloudflare/d1. There are no other projects in the npm registry using @cloudflare/d1.

You don't. If you add a D1 Binding to your Worker, then it will just work

export default {
  async fetch(req, env) {
    // ...
    const result = await env.D1.exec("SELECT * FROM db;");
    // ...
  }
}

export default {
  async fetch(req, env) {
    // ...
    const result = await env.D1.exec("SELECT * FROM db;");
    // ...
  }
}

  async fetch(req, env) {

    const result = await env.D1.exec("SELECT * FROM db;");

Pages Functions is the same, it should be present on the

I'm a little stupid, for the .env item what should i add? my wrangler.toml file looks like this but i dont think its working:

[[d1_databases]]
binding = "DataB"
database_name = "thing"
database_id = "dwadwadwad3213dsfasfdaeiu2"

[[d1_databases]]
binding = "DataB"
database_name = "thing"
database_id = "dwadwadwad3213dsfasfdaeiu2"

[[d1_databases]]
binding = "DataB"
database_name = "thing"
database_id = "dwadwadwad3213dsfasfdaeiu2"

[[d1_databases]]
binding = "DataB"
database_name = "thing"
database_id = "dwadwadwad3213dsfasfdaeiu2"

if i have to create a .env file would i format it the same way?

You don't use

for Pages, you pass bindings via the CLI

Is it possible to cache database queries using the cache API inside workers? Do you simply make a response with the data with some random url and call it a day?

wrangler d1 execute EmailTracker --command='SELECT * FROM SenderInfo WHERE email = "drnewt536@gmail.com";' fails, yet

It is not. The batch runs in an implicit transaction, so that a batch doesn’t “partially” complete and leave your database in an unexpected state.

Matt SilverlockOP•6/13/23, 7:58 PM

That’s not how a transaction works. What if some of those earlier queries insert data? Modify the schema? Or return nothing? etc.

If you need to treat them as discrete queries, issue multiple separate queries

Some of the discussion actually reminded me of a question I have had since wrangler3/miniflare3 came out.
With those old miniflare packages (https://www.npmjs.com/package/@miniflare/d1) when in a test environment, you could write code that would simulate d1 in the following way

import { D1Database, D1DatabaseAPI } from "@miniflare/d1";
import { drizzle } from "drizzle-orm/d1";

const d1 = new D1Database(new D1DatabaseAPI(sqliteDb));
const db = drizzle(d1); // now I can can write unit tests for drizzle

import { D1Database, D1DatabaseAPI } from "@miniflare/d1";
import { drizzle } from "drizzle-orm/d1";

const d1 = new D1Database(new D1DatabaseAPI(sqliteDb));
const db = drizzle(d1); // now I can can write unit tests for drizzle

import { D1Database, D1DatabaseAPI } from "@miniflare/d1";
import { drizzle } from "drizzle-orm/d1";

const d1 = new D1Database(new D1DatabaseAPI(sqliteDb));
const db = drizzle(d1); // now I can can write unit tests for drizzle

import { D1Database, D1DatabaseAPI } from "@miniflare/d1";
import { drizzle } from "drizzle-orm/d1";

const d1 = new D1Database(new D1DatabaseAPI(sqliteDb));
const db = drizzle(d1); // now I can can write unit tests for drizzle

How can I write this with miniflare 3?

Jason Hostetter•6/14/23, 2:53 AM

I ended up refactoring my query into two separate queries, which now seems to keep it under the depth of 20 limit. I initially had the queries combined with nested CTEs so that I could avoid two DB round-trips, but it seems like the speed of the new backend more than makes up for it. It's really fast now.
