Are you able to request a limit beyond that or is it still a hard-coded value like in the beta?

Matt SilverlockOP•4/3/24, 2:22 AM

We don’t currently increase that limit - it’s not that it’s hard coded, it’s that we have a very (very) high bar for performance & cold starts.

We’re continuing to work on raising it over time - and as we do it’ll just work. But also unlikely a single D1 DB will be 100GB (which is a large transactional DB by any standard)

Matt SilverlockOP•4/3/24, 2:23 AM

Keep in mind that a 10GB database storing user records @ 1KB per row = 10M users.

Village (Josef)•4/3/24, 2:24 AM

That's fair yeah, we're considering a serverless migration at work and our current DB is 108GB (we can't split by user with our use case) so size is the issue

does SQLite View improve query speed? I'm not planning to join view with anything else

Same here. I tried specify a region and it works.

Are you still seeing this? I was able to create a new DB just now.

OK, looking into it. My new DB was automatic (based on your previous comment).

Tony Leung•4/3/24, 1:37 PM

Hi guys, is there anyway to turn off foreign key check while migrating the database? Some table altering tasks needs table to be dropped, which will cascade referenced tables.

D1 supports defining and enforcing foreign key constraints across tables in a database.

Tony Leung•4/3/24, 1:46 PM

This works with table creating or importing but not for table dropping. Matt also suggested me to bracketing the migration by that pragma but sadly it didn't work

Village (Josef)•4/3/24, 2:23 PM

Got another question, there's still no way to dynamically bind to databases correct? I.e. bind to all 50k DBs from a Worker instead of the ~5k that'll fit in wrangler.toml? I believe you can use the API, but that kind of defeats the purpose.

kian•4/3/24, 2:25 PM

Correct

Original message was deleted

Tony Leung•4/3/24, 2:26 PM

Yeah I think it's the only way to add foreign key or change column type, but whenever I drop the table, all records in tables which reference to the table dropped before are gone too because of cascading on delete.

Tony Leung•4/3/24, 2:30 PM

My current approach is store the child table data to a temp table then insert it again after migrating the parent table. But when my child table also has some more children, the task turns out to be complex and wasteful

Kkian Correct

Max (@rozenmd)•4/3/24, 5:03 PM

The REST API is significantly slower than a Worker, would recommend a simple wrapper over a Worker instead: https://github.com/elithrar/http-api-d1-example

Is it possible to share a d1 database between worker and pages locally?

Cory•4/3/24, 6:48 PM

I am trying to understand how session-based consistency would work in an application such as SvelteKit and the data invalidation methods. I understand the example of consistency when executing multiple queries in the same function, but how can I guarantee that the next reload of the page will be up to date? Does anyone have any examples of this?

Cory•4/3/24, 8:03 PM

Yes, but how can I know that the read replicas are caught up at that point

Ggotfredsen but .. where is the D1 download .. / export .. for backup ? 🙂

it's an upcoming feature which breaks compatibility with previous API

LLordSilver it's an upcoming feature which breaks compatibility with previous API

zegevlier•4/3/24, 9:15 PM

It doesn't break compatibility with the old API, you can still use the old API just fine. It's just that there is no change to behaviour of the "old" API when the new API is introduced

zegevlier•4/3/24, 9:18 PM

I can't confirm whether you'll be able to use them simultaneously, but D1 is a GA product, so I would not expect any of the current APIs to change in a backwards-incompatible way.

Unsmart•4/3/24, 9:20 PM

If theres any changes it will be guarded by a compat date/flag

Matt SilverlockOP•4/3/24, 9:58 PM

Exactly this.

You can use the existing

env.DB.prepare()

env.DB.prepare()

and other APIs, or you create a session via

let session = env.DB.withSession(commitToken)

let session = env.DB.withSession(commitToken)

and then call

session.prepare()

session.prepare()

session.batch()

session.batch()

, etc, etc.

We aren't breaking the APIs. Users that never adopt the session API will have D1 as it works today, with the same consistency model they've built their app against.

Developers who want to use replicas can adopt the session API.

forslunds•4/3/24, 10:02 PM

Do we really need replicas if we go 1db/user

if we dont have heavy writes ofc

Unsmart•4/3/24, 10:05 PM

replicas only helps with reads not writes

johtso•4/3/24, 10:57 PM

are there any tools that let you explore your d1 database with a gui similar to drizzle studio?
