MMax (@rozenmd)and you're not calling any other service in that Worker?

oscarOP•1/8/25, 2:18 PM

honestly haven't had the time to dig deeper on that specific call but it's most probably an alarm trigger on a DO in a Worker that also interfaces with R2, KV and other Workers. Each specific DO alarm trigger may or may not interface with each of these services depending on the characteristics of the long running job it's running.

Chaika•1/8/25, 3:42 PM

I've gotten that exact same error from R2 before, you mention using R2 so probably that, just need to retry

Greenrider•1/8/25, 6:33 PM

Has anyone run into an issue with 504s back from D1 when using Wrangler to do load a .sql migration file remotely? It worked the first time, but now when I want to update the DB, I'm able to upload the .sql to remote and then I immediately get a 504 gateway error before anything in the .sql runs on remote

Billy•1/8/25, 9:38 PM

Is anyone aware of an existing tool that will take a D1 export and save the file directly to R2? I know I can do all this programmatically but I was hoping there was a simpler way or a pre-existing tool for it already. Thanks

True, that may be R2. We do get some D1 errors periodically, sent you some examples on DM. Might be just a case of implementing retries?

esselungo•1/9/25, 8:55 PM

what would be the best setup for a grid of points being written every minute? i used to just write one row per point but d1 is just too expensive so i want to reduce the rows written

esselungo•1/9/25, 8:55 PM

is d1 even the best for that

Bailiwic•1/9/25, 9:56 PM

My build keeps looking for DATABASE_URL environment variable, but I'm using settings/binding to bind my D1 instance. I can create the variable, but don't know what to put in it since the binding doesn't have a url.

lambrospetrou•1/10/25, 1:17 PM

This error is probably coming from Prisma then. I am not familiar with Prisma, unfortunately, so hopefully someone else can chime in. In pure Worker projects nothing asks you for a database URL, since as you said D1 doesn't have a database URL.

besimking•1/10/25, 1:19 PM

Is there any possiblity for cloudflare to serve convex as a baas in the near future? Since it is open source

besimking•1/10/25, 1:22 PM

I kind a need a realtime db, that's why I asked this question

mihaaai•1/10/25, 2:00 PM

Does maximum sql statement lengthmaximum sql statement length of 100,000 bytes (100 KB)100,000 bytes (100 KB) also includes binding values? Since Maximum string, BLOB or table row sizeMaximum string, BLOB or table row size is 2MB2MB, are values ignored from the previous constraint?

Bailiwic•1/10/25, 2:01 PM

For anyone interested, Prisma requires DATABASE_URL environment variable, even in production and using D1 binding. The value of the variable doesn't seem to make a difference.

Isaac McFadyen•1/13/25, 12:13 PM

This command runs some SQL on a remote D1 database. It works regardless of where the database is linked. If that database is linked to Pages then yes this will work.

Leo•1/13/25, 8:57 PM

Why is the number of read rows so high again? For 24 hours, I managed to optimize my database by adding indexes, but since 5 P.M. UTC everything is like before.

lambrospetrou•1/13/25, 9:16 PM

Your database is fine, no errors at all. You have two SELECT queries that are causing this I think probably due to lack of index. Make sure you applied your changes/optimizations on the remote database and you didn't only update a local test database if using wrangler.

Check the D1 insights in the dashboard for slow queries to see your slow queries and confirm if the indexes you added apply to those queries (their where filters).

Leo•1/13/25, 9:29 PM

The indexes worked yesterday and if I query the DB using the dashboard, a fairly normal row count appears... and I did not change anything since 12:00 today. I still don't see where the issue is and how to optimize these away.

lambrospetrou•1/13/25, 9:35 PM

If you copy paste your slowest query in your D1 console dashboard and run it prefixed with

EXPLAIN

EXPLAIN

you are hopefully going to see if the database does a scan or if it's uses an index.
There isn't anything problematic with your database either way or a broader issue, so it's something with the query.

Leo•1/13/25, 9:35 PM

Ok, thank you, I'll take a look on this tomorrow.

Most of Cloudflare's dev platform requires some sort of custom middleware at some point. Durable Objects might be a solution to your problem, but again you'll need some amount of custom middleware

Interesting, great to know now than later.. didn't want to dig to deep into something that I'm just going to have to migrate away from anyways.
