ajgeiss0702•4/10/25, 7:36 PM

intermittently or every request?

A

ajgeiss0702•4/10/25, 7:37 PM

I get that too, but last I saw they were recommending people retry the request when reciving that error

M

MozzyOP•4/10/25, 7:39 PM

occasionally, but, started a few hours ago. Could be read replication perhaps, but the error isn't helpful

A

ajgeiss0702•4/10/25, 7:40 PM

actually I just checked my logs, and ive seen more of those recently than usual too

ajgeiss0702•4/10/25, 7:40 PM

first one for me was April 10, 2025

Any particular region?

A

ajgeiss0702•4/10/25, 7:44 PM

that might have been around when I enabled replication for that db, but i didnt record exactly when I enabled it so im not sure.
but the workers arent using the session api at all yet

MMilan Any particular region?

ajgeiss0702•4/10/25, 7:45 PM

the database is located in WNAM, let me check the colo of the requests with errors

A

ajgeiss0702•4/10/25, 7:48 PM

there doesnt appear to be a common colo. some in europe, some in asia, and a few more errors from YYZ and Chicago (which are the colos that my site gets the most requests from anyway)

Is it possible to create new databases dynamically yet? Or are we still stuck with being unable to on-the-fly create and interact with them?

dynamic bindings are not released yet. Until they are, Durable Object's SQL storage is something you could look into, since you can create an unlimited number of objects, and each has seperate storage.

Isaac McFadyen•4/10/25, 8:26 PM

No worries - yeah I don't know specifics of what would be affected, just that some internal API is having issues, R2+D1 are affected, and that engineering is engaged internally

Z

Zack•4/10/25, 8:26 PM

Fair enough, my main addition then is that this isn't affecting our production databases, just this one with replication enabled. Unsure if that's relevant or just coincidence

N

Nikolas•4/10/25, 8:27 PM

The problem we currently face is, when the d1 write succeeds and doesn't throw "internal error", it doesn't write all the columns, only the first ones. We do a big insert query through the API. I assume there is a grater issue with d1 right now?
