The

storage operation exceeded timeout which caused object to be reset

storage operation exceeded timeout which caused object to be reset

is an error specific to slow user queries. What query were you trying to run? How often do you run this, and how often do you get this error?
Also, when reporting issues, putting your database ID is always helpful, otherwise we can't really help with abstract reports. In most cases this error is reported, it's a user error with a slow query or a query without indexes, so help us to help you

Queries number across a whole day is not very relevant for this overload error. Overload error is usually because of sudden spikes, not because of total load across a day.

errors on 2025-02-28 around 14:26-14:33GMT, and

errors around 2025-03-01 14:33 GMT. I don't know exactly which queries were associated with the errors, but the Query Latency metrics show the P95 latency can't have been higher than 8-10ms. My most frequently run queries have a P95 latency of 0-3ms.

Not with interleaving JS code if that's what you mean. Each batch query or single query you send to D1 is running within a transaction.

I only see the

storage operation exceeded timeout

storage operation exceeded timeout

errors at that exact timestamp (

2025-03-01 14:33 GMT

2025-03-01 14:33 GMT

) on your database, nothing else before or after, so it might have been something transient or maybe a query slowdown momentarily if the machine had any issue.
Same for the overload errors. I don't see other errors except that one time.

If your queries are idempotent (e.g.

insert if not exists

insert if not exists

) or selects, then retrying them is always suggested.

We have some plan to document some of these errors and denote which are retryable, but if you design your queries to be "safe" to retry you can already do it yourself. This will pretty much cover these one-time errors.

Matthew•3/5/25, 12:46 PM

Thanks for looking into it! Have to say, there are more transient/one-off errors than I had expected when I based my app on D1, and I wasn't aware I would have to write query-retry code

andifined.dev•3/5/25, 4:40 PM

Maybe asked some time ago. But docs state some kind of dB per user. I‘m wondering how that should be possible with d1? And how to handle dB Migrations?

marko.333•3/5/25, 6:57 PM

Does anyone know if there are plans to add support for embeddings/vectors to D1 (maybe via Vectorize integration)? I would like to merge/rank D1 queries (BM25) with dense embedding ranking? For now are there any good workarounds?
Thx.

I hope this message finds you well. I’m reaching out to request your assistance with an issue I’m experiencing with my D1 database.

Currently, I’m unable to access my database with the ID 1bad90ef-990b-4ad1-908b-4bddd1f3ffd9. When I try to view its status through the Cloudflare Dashboard, it remains stuck in a "loading" state indefinitely. This issue is preventing me from managing or using the database effectively, and I’m unsure of the underlying cause.

Could you please help me investigate what might be going wrong? I’d greatly appreciate any insights or guidance you could provide to resolve this.

Thank you in advance for your support! Please let me know if you need any additional details from my side to assist with troubleshooting.

beelzabub•3/6/25, 4:58 PM

I store base32 and base64 strings within sqlite. It would be nice if D1 supported extension functions to encode blobs as base32/base64 / decode base32/base64 strings (akin to hex/unhex that do the same)

beelzabub•3/6/25, 4:59 PM

It just makes it more convenient when running queries directly to debug stuff vs having to write JS to interpret the DB.

Hey Team, I am based in Sydney Australia, and trying D1 + Cloudflare pages using Drizzle ORM.
I am experiencing, each DB Call takes at least > 230 miliseconds.
I found multiple forum, people discussing D1 queries taking time. (I have created indexes, but that should not be a problem, since my DB is very small , with few test data in KBs).
Is this latency due to D1 not closser to my Pages Worker?

Hi, if you have multiple workers needing to talk to the same d1 instance when doing local development? How do you achieve that?

  /app2

Every D1 response now has a

To get the location of your worker, as others mentioned above you can use Cloudflare headers of the request telling you the
