If you do

do you see

There should be a

running_in_region

running_in_region

field right between the size and read query count... strange that you don't see it

Chaika•10/30/24, 3:58 AM

What do you mean "Current regions"? D1 only runs in a single region/location, if you don't specify a location hint it just does it off the requestor's location, and it'll stay there forever

FFlikTeoh Yeah. What I mean is that, other db that was created without location hints, sho...

C

Chaika•10/30/24, 4:01 AM

hmm I can't reproduce that. If you have a second, try making another with the same location hint? Just trying to understand scope, I'd guess it's a weird one-off issue
The --json option is just returning what the database get endpoint responds with + graphql, so it missing is api being confused/not a specific wrangler thing

what's the date of creation on that db?

Chaika•10/30/24, 4:09 AM

there's going to be some cold start time but shouldn't be that much

C

Chaika•10/30/24, 4:09 AM

where are you getting the response times from? The D1 Console wouldn't be a good indictator of response time for example, all requests still have to go you -> core -> d1 instance afaik

FFlikTeoh Yeah it was in the 1.5s to 2s range last week. Yesterday it was at 4.4s. Which w...

C

Chaika•10/30/24, 4:12 AM

it wouldn't go to sleep if it was constantly being accessed, if you're getting 800ms on some subsequent requests that's still pretty high though

Chaika•10/30/24, 4:13 AM

hmm that one's 0.3ms on avg

C

Chaika•10/30/24, 4:13 AM

800ms is really high if you have smart placement on, possible that it being borked is connected to the api not showing the location though

FFlikTeoh I can't remember the exact location hint I gave when I created that db. But I th...

C

Chaika•10/30/24, 4:14 AM

with smart placement on, what was the cf-placement response header?

C

Chaika•10/30/24, 4:20 AM

Smart Placement is currently ignored when making RPC calls. If Smart Placement is enabled for Worker A, and Worker B declares a Service Binding to it, when Worker B calls Worker A via RPC, Worker A will run locally, on the same machine.

C

Chaika•10/30/24, 4:20 AM

even if it did work if the underlying d1-calling worker was called via rpc the header wouldn't be passed up anyway

C

Chaika•10/30/24, 4:23 AM

means it's running wherever the original worker is running, which would be a cf location close to the requestor

C

Chaika•10/30/24, 4:25 AM

essentially yea. Assuming APAC is your location/the location you're calling the worker from. Not 100% sure about normal, still seems a bit high to me, don't understand how you're measuring the ~400-800ms response time though

CChaika what's the date of creation on that db?

I noticed that some databases display "running_in_region," while others do not. I suspect that the ones not displaying this might be due to not specifying a location during creation, and the system automatically determined one.

JJames It's absolutely a valid concern and I don't think anyone is arguing that - if yo...

Hey this is kinda off topic for d1 but was just reading through and a question came to my head is their any way of protecting againts a DNS going down. Like i think cloudflare DNS went down a few times before is it just pray it doesnt happen or is their any way around that?

JIYU•10/30/24, 7:12 AM

Is it just me or are these errors bound to happen as long as I'm using D1? I've been getting a lot of these errors yesterday.

Increase in D1 Errors

N

naourass•10/30/24, 2:31 PM

I'm trying to apply a migration on a

preview

preview

preview

preview db, but the command is failing with

Exit Code 1

Exit Code 1

Exit Code 1

Exit Code 1 without any error message. Any idea what am I doing wrong or what could be the error cause here?

Update: Issue resolved, I had to create an independent preview database and pass its id to

preview_database_id

preview_database_id

. Note that doing this will change the id of your local database too if any.

Here's my

wrangler.toml

wrangler.toml

db config:

[[d1_databases]]
binding = "CORE_DB"
database_name = "phoenix-core-prod"
database_id = "xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx"
migrations_dir="database/migrations/core"
preview_database_id = "CORE_DB"

[[d1_databases]]
binding = "CORE_DB"
database_name = "phoenix-core-prod"
database_id = "xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx"
migrations_dir="database/migrations/core"
preview_database_id = "CORE_DB"

[[d1_databases]]
binding = "CORE_DB"
database_name = "phoenix-core-prod"
database_id = "xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx"
migrations_dir="database/migrations/core"
preview_database_id = "CORE_DB"

[[d1_databases]]
binding = "CORE_DB"
database_name = "phoenix-core-prod"
database_id = "xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx"
migrations_dir="database/migrations/core"
preview_database_id = "CORE_DB"

Here's the

npm

npm

script:

"db:migrate:core:preview": "wrangler d1 migrations apply phoenix-core-prod --remote --preview"

"db:migrate:core:preview": "wrangler d1 migrations apply phoenix-core-prod --remote --preview"

"db:migrate:core:preview": "wrangler d1 migrations apply phoenix-core-prod --remote --preview"

"db:migrate:core:preview": "wrangler d1 migrations apply phoenix-core-prod --remote --preview"

And here's the command result:

Hello, I’m Allie!•10/30/24, 2:50 PM

Note DB IDs(and the rest of your wrangler config) are not secret, as anyone would need access to your account to make use of it

N

naourass•10/30/24, 3:01 PM

Thanks for the note! Back to the issue, I'm note sure if I should create an independent preview db and pass its id to

preview_database_id

preview_database_id

. Can anyone confirm?

N

naourass•10/30/24, 3:51 PM

Just tried that

and the migration command was applied successfully!

So how do you access these different bindings in your code? In the past, all environments could have the same DB binding name for all environments.

Now, do I have to do something like this?

let db = c.env.DB_DEV;

if (c.env.??? === "staging") {
  db = c.env.DB_STAGING;
}

if (c.env.??? === "production") {
  db = c.env.DB_PRODUCTION;
}

let db = c.env.DB_DEV;

if (c.env.??? === "staging") {
  db = c.env.DB_STAGING;
}

if (c.env.??? === "production") {
  db = c.env.DB_PRODUCTION;
}

let db = c.env.DB_DEV;

if (c.env.??? === "staging") {
  db = c.env.DB_STAGING;
}

if (c.env.??? === "production") {
  db = c.env.DB_PRODUCTION;
}

let db = c.env.DB_DEV;

if (c.env.??? === "staging") {
  db = c.env.DB_STAGING;
}

if (c.env.??? === "production") {
  db = c.env.DB_PRODUCTION;
}
