Since d1 uses SQLite internally, does it run into the same limitations as SQLite, namely handling large number of independent writes/sec. From what I read SQLite is not capable of handling more than 1000 write reqs/sec.

Currently for open beta, ~1K QPS depending on result set size. Our eventual goal is to get 3-10K QPS for reads, 1-2K QPS for writes. Let us know what requirements your workload would need?

Sounds good, thank you! And I meant storage per account and number of DBs specifically

Can you promise at this point that the D1 size limitations will begone

janat08•11/29/23, 8:52 AM

You recommend against building on D1 for production, but surely not because you still have forseeable hard limits on db size?

I don't think it is ever going to be unlimited, but it is definitely going to be higher than it is now

janat08•11/29/23, 9:01 AM

Do you get to shard it or something once at the ceiling. You mean I won't be able to have a petabyte db on cf, but my question is if at some point I'd have to close registration at my app because of the storage limit?

Hello, I’m Allie!•11/29/23, 9:04 AM

I think it is also a case of understanding what platforms are built for. While it would be nice theoretically if D1 could scale infinitely, in practice, if you do get to Petabyte scale, you should probably look at a DB specfically built for that. Until then though, D1 is a good choice

janat08•11/29/23, 9:22 AM

Is there going to be some library for sharding, where you can have multiple d1 dbs, and get to treat them one, so as to bypass the size limitation at the expense of extra reads

Max (@rozenmd)•11/29/23, 9:28 AM

we have folks building products that have 1 db per customer, where each db has the same schema, just stores different data
though migrations + dynamically binding to new dbs are a pain point

is there some kind of workaround, or limitations improvement to make d1 fit for general usage?

Max (@rozenmd)•11/29/23, 9:40 AM

It doesn't sound like D1 fits your use case if you're worried about petabyte scale. Hyperdrive is probably a better fit: https://developers.cloudflare.com/hyperdrive/

janat08•11/29/23, 10:38 AM

I have no reason to worry about petabyte scyle, but surely anyone is hitting the 2gb limit

kian•11/29/23, 11:04 AM

This is a beta-only limitation. The D1 team will increase the maximum storage per-database, storage per-account and number of databases for Paid plans during the course of D1’s public beta.

kian•11/29/23, 11:05 AM

They're beta limitations - there is no forecasted hard limit, but there will naturally be one even in GA.

What errors are you seeing?

talfiz•11/29/23, 4:17 PM

after successfuly inserting into the table (I can see the values in the UI) if I try to edit / insert from the ui or with code i get the error FOREIGN KEY constraint failed (Code: 7500) , and If I try to delete the whole table from the UI Its telling me to try again later (its the same for two days)

talfiz•11/29/23, 4:19 PM

I believe its a bug

Even tables with no binary

Rob M.•11/29/23, 4:41 PM

Can you send a snippet with your "env" usage?

Rob M.•11/29/23, 4:44 PM

By the way, you should use 'context.env.*' instead of 'env.*' in Page workers. Maybe that's the issue.

talfiz•11/29/23, 5:56 PM

Hi guys I fixed the bug what I tried to do is to delete a user when a teacher is still refrenceing him to do that I should add ON DELETE CASCADE to the table thanks for however tried to help

You talk below about cases where people create 1db per user.. But to be more efficient, if I want to create 1 db per region (enam, wnam...) and redirect each user to the closest/fastest db, is there a way to programatically do that? with the CF-IPCountryCF-IPCountry header ? but should I build a table with states on the east/west cost ... and redirect based on it? or is there a way to get a ping to the D1 center location?

rodrigo•11/30/23, 9:59 AM

And regarding Asia-Pacific region .. that is a region too big (Australia, China , India ...). Is there (or will there) a way to allocate D1 dbs to smaller areas within the region?

the Workers platform is built in such a way that you should never need to make decisions like that - we know where your requests are coming from and should route them to the nearest replica for you, without your input (except for cases where you've opted into keeping data in certain regions)

Max (@rozenmd)•11/30/23, 12:09 PM

I was talking more about the case where you want to have several D1 dbs so that you have several writers. In this case, there is a way to redirect users to its closer db writer ?

Support for more than 100,000+ databases for Workers for Platforms users — there’s no limit, but if we said “unlimited” you might not believe us — on top of the 50,000 databases per account that D1 already enables.

From https://blog.cloudflare.com/d1-open-beta-is-here/

D1: open beta is here

D1 is now in open beta, and the theme is “scale”: with higher per-database storage limits and the ability to create more databases, we’re unlocking the ability for developers to build production-scale applications on D1

Matt Silverlock•11/30/23, 11:44 PM

It can depend - this isn’t final yet and there may be cases where we should count rows read. Note that no one is actively billed just yet.

Since d1 uses SQLite internally, does it run into the same limitations as SQLite, namely handling la
