Anyone spotted these improvements in their metrics for Workers using D1?

https://developers.cloudflare.com/d1/platform/changelog/#2025-01-07

Chaika•1/21/25, 6:47 PM

yes :MeowHeartCloudflare:

Teejers•1/21/25, 7:35 PM

Hey everyone! Is there any way to give other users access to view d1 in the cloudflare dashboard? Right now it says 403 for them.

Can I configure CORS headers for my D1 DB when used over REST API? I'm trying to query it from the browser, but the missing CORS headers makes it very hard. no-corsno-cors-mode strips the Auth header, so that's also not an option.

Jenkins•1/21/25, 9:08 PM

Just feels so wasteful to have to set it up just to serve as a dumb proxy. Performance is not really a worry for this app.

But thanks for the info anyways. Are there no other workarounds?

I don't think it's a good idea either, your API token will be exposed and anyone can query whatever they want with your database, eg deleting all tables.

Jenkins•1/21/25, 10:24 PM

I am aware of the security implications, and they are handled by me manually adding the acc and DB ids as well as the token on a config page and storing them in local storage. This is just a personal app meant to sit behind CF ZeroTrust.

I will just set up the proxy. I think the lack of CORS headers should be either documented or be configurable like with R2.

Max (@rozenmd)OP•1/22/25, 7:45 PM

Rolled out a quick update on the D1 insights view in the dash (click on your D1 DB -> scroll down):

You can now search, and there are heaps more results

(more updates coming)

Hi everyone, I have questions regarding D1 db count limit:

Is it possible to have more than 50,000 dbs? Reason: I'm planning to use 1 db per user and the user count might grow beyond 50k.
Second, does this limit apply to DO backed by sqlite?

No.

*with the caveat that the account DO storage limit applies I believe, correct?

50GB but you could reach out and get it raised possibly

Is there a service outage with D1 at the moment? I'm getting huge latencies trying to read a small DB and my queries don't take much time at all, usually <200ms at most

The CF worker that's using it is only getting 16 req / s max, wouldn't have expected any issues from this kind of load? (worker ID f1464da9-c78b-42c2-b197-fc60492ca704f1464da9-c78b-42c2-b197-fc60492ca704)

We started rolling out a feature around 1600 UTC, the team is investigating if it's related

Max (@rozenmd)OP•1/23/25, 5:49 PM

16 RPS should be more than fine, but depends on how complex the query is

jims0209•1/23/25, 6:24 PM

Yeah the performance is pretty bad now. Even the CF D1 dashboard is slow to load

Wall times have come back down to normal right before 20:00 UTC

how to migrate from 001 migrations --> 002 migrations if a table already exist, this error confusing via wrangler. all example is writter from empty table not an existed one

Max (@rozenmd)OP•1/24/25, 12:41 PM

your migrations shouldn't be trying to create a table that already exists, but you can update your SQL to CREATE TABLE IF NOT EXISTSCREATE TABLE IF NOT EXISTS to avoid the error. it sounds like there's something wrong with your setup if you already have tables and are trying to run migrations to create them, though.

Isaac McFadyen•1/24/25, 12:42 PM

^ migrations are not meant to be indempotent, instead there's usually a table created within the DB that stores the migration name/ID and whether it's already been applied

Isaac McFadyen•1/24/25, 12:42 PM

That way you don't re-run the same migration twice.

It looks like you're trying to create a unique/primary/foriegn key that already exists?

What's your SQL statement?
