Thank you for your feedback, few weeks ago I could create one in local, I don't remember how, may be with the --local ( or without the --remote flag, this is not really clear when we need one or not )

Currently, if I don't uses the --local flag, it's create the DB in remote ( and without any --remote flag )

I've got a wranger.toml file like so

[env.production]
name = "krypton"
logpush = true
workers_dev = true
d1_databases = [
  { binding = "DB", database_name = "krypton", database_id = "<123>" },
]

[env.production]
name = "krypton"
logpush = true
workers_dev = true
d1_databases = [
  { binding = "DB", database_name = "krypton", database_id = "<123>" },
]

[env.production]
name = "krypton"
logpush = true
workers_dev = true
d1_databases = [

name = "krypton"
logpush = true
workers_dev = true
d1_databases = [
  { binding = "DB", database_name = "krypton", database_id = "<123>" },

When I deploy, it deploys with the D1 database as expected bound. However when I run:

wrangler d1 migrations apply krypton

wrangler d1 migrations apply krypton

I get the error,

Hello
Can anyone guide me on how to connect workers with Cloudflare d1 and different environments
The connection is fine if i go with the default wrangler.toml configuration but the moment i go with this approach (Check code below) the db connection never happens at all

Approach i am trying to use

This is a staging environment

[env.staging]
d1_databases = [
{ binding = "DB", database_name = "<DATABASE_NAME_1>", database_id = "<UUID1>" },
]

This is a production environment

[env.production]
d1_databases = [
{ binding = "DB", database_name = "<DATABASE_NAME_2>", database_id = "<UUID2>" },
]

MY BINDING

export type Bindings = {
    DB: D1Database;
    ACCESS_TOKEN_SECRET: string;
};

export type Bindings = {
    DB: D1Database;
    ACCESS_TOKEN_SECRET: string;
};

my endpoint (Using hono js)

app.get('/', async (c) => {
    const res1 = await c.env.DB.prepare('SELECT * from testTable;').all();
    return c.json({ status: 'success', message: res1 });
});

app.get('/', async (c) => {
    const res1 = await c.env.DB.prepare('SELECT * from testTable;').all();
    return c.json({ status: 'success', message: res1 });

Ok this is crazy but i found the issue and it would be reall super nice if we could get a better solution to this
for D1 connection you need to use
[env.dev]

and for actual environment variables you need to use
[env.dev.vars]

Yes many would say that its on the documentation (both in workers and D1 docs) but its super difficult to ge this correct from the first time
i spent an entire day on this

AND PLZ dont get me wrong, cloudflare solutions are super amazing but if we could get a better way of doing this environment thing

Lane C•10/13/23, 11:06 PM

I did have one index to fix and that has increased performance a lot.My db was also the alpha version, so I recreated with beta, I have no idea how that happened. Its still about 1.2 seconds to load 10 records on a query with 4 joins and a base table of 10k rows. FWIW here is a front end demo. if you page thru enough times, you'll hit a page that hasn't been cached and can see the latency. https://client-demo.sonicjs.com/

Our table has 5 columns, using INSERT INTO I was able to insert a row with 5 values using the query api. I did

"sql": "INSERT INTO table (channel, title, start_time, end_time, description) VALUES (?, ?, ?, ?, ?);"

"sql": "INSERT INTO table (channel, title, start_time, end_time, description) VALUES (?, ?, ?, ?, ?);"

Is it possible to insert multiple rows with one quest? Something like

Jason Hostetter•10/14/23, 1:17 AM

Question regarding the proposed pricing: from what I’ve read, pricing is based on row writes/reads regardless of row size. This penalizes normalization then right? I have a schema that normalizes metadata for Dicom files, which is usually many small key value pairs that are very redundant. In other words, storing the denormalized metadata would waste a lot of storage, but normalizing means I have many small rows which then costs more. For example, a typical request might load metadata for 500 files, each file with 100 data items. So that’s at least 50,000 read units for one request right? Or I could stuff all the metadata for each file into one row, where maybe 60-80% of the data is identical. Considering there is a ceiling on storage with D1 I’m not totally sure where to draw the line here.
