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;
};

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 });
});

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 });
});

i then get the following error

Does wrangler dev —env stagingwrangler dev —env staging work?

TalaatOP•10/13/23, 3:07 PM

unfortunately no

however if I change
[env.dev.vars]
to
[env.dev]
it does work but it only picks up the db connection and ignore other variables like the access token

Cyb3r-Jak3•10/13/23, 3:12 PM

Can you share your full wrangler file. My guess is this is toml inheritance being weird

deleted your message, it seems to contain secrets

TalaatOP•10/13/23, 3:27 PM

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

MMax (@rozenmd)deleted your message, it seems to contain secrets

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/

looking for something similar to this maybe

Samantas5855•10/14/23, 12:49 AM

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

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

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

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.

Denormalized rows can often be more efficient in real life. I'm experimenting with JSON fields for this

Samantas5855•10/14/23, 12:36 PM

also would it be possible to do

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

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

instead of doing

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

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

Seems like there is confusion on Worker API and REST API methods/endpoints

Cyb3r-Jak3•10/14/23, 12:47 PM

@Samantas5855 The

/query/batch

/query/batch

endpoint exists for the worker because it calls the

.batch

method through the Workers API. All of the endpoints in the worker are just ways to access the Workers API bindings

Cyb3r-Jak3•10/14/23, 12:51 PM

If the worker was written that way then yes. The endpoints in the worker can be set to whatever as it just translations from a REST to the Workers binding

Samantas5855•10/14/23, 12:51 PM

by calling the query api like that

  --data '{
    "params": [
        "a",
        "b",
        "c",
        "d",
        "e",
        "a2",
        "b2",
        "c2",
        "d2",
        "e2"
    ],
    "sql": "INSERT INTO myTable (f1, f2, f3, f4, f5) VALUES (?, ?, ?, ?, ?), (?, ?, ?, ?, ?);"
}'
