If your FTS queries scan multiple columns you need to ensure your indexes cover those columns: https://developers.cloudflare.com/d1/best-practices/use-indexes/

Cloudflare Docs

Use indexes · Cloudflare D1 docs

Indexes enable D1 to improve query performance over the indexed columns for common (popular) queries by reducing the amount of data (number of rows) the database has to scan when running a query.

If this 1k writes/s is for a single database, and you could be writing many rows each time, you are at the border of what you can do. It means you should not spend more than 1ms per query. Doable if they are selects, but for writes it will really depend on many factors.
Batching even more earlier, or using a few database instances would give you a lot more room and flexibility.

Is there anything you can do to mitigate

D1_ERROR: Internal error while starting up D1 DB storage caused object to be reset.

happens fairly regularly, all you can do is re-attempt your query

J

James•12/20/24, 11:58 PM

Yeah, hopefully we'll get some better documentation around error rates and safely retriable ones as per https://github.com/cloudflare/cloudflare-docs/issues/18485. Until then, unfortunately all you can do is retry or use another more stable database provider if the error rates aren't acceptable for your use-case.

I tried that obviously, but my database seems to be locked up in this state. It’s all it gives back for the past 14 hours. Can’t connect to it through web, wrangler or code.

Dean•12/21/24, 8:37 AM

ah, sounds like it's very broken, my D1 databases do that periodically but usually only briefly

K

Kyrre•12/21/24, 8:42 AM

When creating a D1 database, I can provide a location hint like EEUR. However, this region is big, and I want to be close to my users. Is there any way of figuring out which data center actually hosts the database, so I can retry until I actually hit the right location? I know about the

d1 info

d1 info

option, but this only returns EEUR.

K

Kyrre•12/21/24, 8:45 AM

My understanding is that D1 is not currently replicated?

K

Kyrre•12/21/24, 8:47 AM

Right, but presumably there is a "primary" data center for the database.

K

Kyrre•12/21/24, 8:49 AM

For one database we have in the WEUR region, it seems to always return MRS in the smart placement header, even though there are several much closer data centers.

K

Kyrre•12/21/24, 8:50 AM

I find it utterly baffling that this information is obscured from us.

this happens because the API for the sqlite d1 file in miniflare is slightly different from the managed postgres api in live. Please share your solution because mine is really dumb
