Hey guys, I was wondering - is there any actual uptime or analytics for the D1 database? On the cloudflarestatus.com website, there's no status for D1 specifically but there are Workers and Durable Objects (I believe D1 is based on them). Is it safe to assume that D1 uptime is basically the same as DO/Workers?

Ccaptain got it! I just set it via: time_stamp_updated INTEGER DEFAULT (unixepoch('now') ...

SQLite is very loose on data types (by default), and won't complain if you put the wrong thing in a given column. To make it more strict you can use: https://www.sqlite.org/stricttables.html
And then on the date/times, you can get a more precise time (sub second) and a human readable ISO form with:

    createdAt DATETIME DEFAULT (strftime('%Y-%m-%dT%H:%M:%fZ', 'now'))

    createdAt DATETIME DEFAULT (strftime('%Y-%m-%dT%H:%M:%fZ', 'now'))

The DATETIME isn't a specific Sqlite datatype, but it distinguishes it from TEXT. Also if you're setting the value from Javascript, use the Date.toISOString().
More info on the SQLite handling of dates/times: https://www.sqlite.org/lang_datefunc.html

May I know when the official version will be released? I am eagerly looking forward to using D1 for my personal project. As long as the subsequent updates do not result in data loss, I am okay with it

Afaik theres never been data loss with D1 and I doubt there will be any

That's great to hear!May I know when the official version will be released?

Theres no GA release date it will come eventually

Jonatan•9/28/23, 8:49 AM

Hello all, when I try to deploy/test my worker it says 'D1 bindings require module-format workers. [code: 10021]'. Could someone pls explain what this means? Am I missing a node module?

Jonatan•9/28/23, 9:11 AM

~~Nvm, I forgot to use the wrangler beta instead of normal wranler~~

Jonatan•9/28/23, 9:35 AM

Yeah I was using script-format workers, whoops

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

D1 is now in public beta, and storage limits have been increased:

Matt Silverlock•9/28/23, 1:23 PM

D1 is now in public beta, and storage limits have been increased:

Developers with a Workers paid plan now have a 2 GB per-database limit (up from 500MB) and can create 50,000 databases per account (up from 10). These limits will continue to increase automatically during the public beta.
Developers with a Workers free plan retain the 500 MB per-database limit and can create up to 10 databases per account.Databases must be using D1's [new storage subsystem](/d1/changelog/#new-default-storage-subsystem) to benefit from the increased database limits. See the announcement blog for more details about what's new in the beta and what's coming in the future for D1.

Hi, need some help guys, new dev here so let me know if I am posting to the wrong channel. I am running wrangler d1 migrations in postCommands after deployment which gives an error but it used to work just fine in the preCommands of the "yml" file. Now, I am getting the error "non-zero exit code"

Epailes•9/28/23, 1:33 PM

Is support for a large number of d1 instances going to be solely tied to Workers for Platforms users (which needs ent contract), or is it something which would be generally available?

Matt Silverlock•9/28/23, 1:35 PM

We can increase on a case-by-case basis. We intend to substantially increase the # of databases per account (per the blog) during the beta period as well.

Matt Silverlock•9/28/23, 1:36 PM

At "100k databases" there are other things that make you want to use WfP in terms of how many bindings you can have per script, how you are managing user scripts, etc.

Epailes•9/28/23, 1:38 PM

Ah I thought if D1 supported a large number of instances it would move to the DO method of connecting where you don't need an individual binding per worker

Epailes•9/28/23, 1:40 PM

At least for the use case where each instance has the same schema and many instances is more a method of sharding to prevent everything being stored in one huge instance which slows down, and there's no legal/contractual requirements to store user data separately.
If each d1 can be unique then platforms makes a lot more sense

I saw Cloudflare added Turso as an integration partner and was wondering the pros/cons of Turso vs D1 in your experience

Ashish Rawat•9/28/23, 2:04 PM

How this will work for 1000s of users if the database limit will be in GB (assuming atmost 10GB in future) with just 25 database per project.

Rryoppippi hi is d1 production ready?

Max (@rozenmd)•9/28/23, 3:10 PM

D1 is in public beta. While we expect breaking changes and issues to be minimal, they may still occur. We generally do not recommend running large production workloads on beta products.

PizzaConsole•9/28/23, 4:28 PM

I see that D1 does not support Transactions or save points. However when using a transaction and running locally it does not throw an error. Is that a change that needs to happen in Miniflare?

nope, as long as your db says "beta" when you run wrangler d1 info, you're all set

You'll need to dump the database to a SQLite file and then re-import to a new (beta) database.

Not if you are on the beta backend.

Matt Silverlock•9/28/23, 7:14 PM

No. ZFS snapshots don’t work like that (and way too low level). D1 has its own storage subsystem that allows this to work.

nclevenger•9/28/23, 7:27 PM

Is there a technical limit to the number of bindings that a worker can have? I'm assuming at some point there is significant performance overhead to add all of the bindings to the envenv object, but what order of magnitude are we talking about here?

Hello, I’m Allie!•9/28/23, 7:28 PM

IIRC it comes down to the metadata limit, which iirc is 1 MB

Hello, I’m Allie!•9/28/23, 7:29 PM

So however many bindings you can cram into that

nclevenger•9/28/23, 7:29 PM

ahh - makes sense

nclevenger•9/28/23, 7:29 PM

I was reading the blog post today and I hadn't realized until then there was a patchpatch method to incrementally add a binding ... that was really interesting to see ...

Hello, I’m Allie!•9/28/23, 7:30 PM

Is that the imposed limit or technical limit?

nclevenger•9/28/23, 7:31 PM

yah - I had been using WfP as a bridge for dynamic user-specific D1 ... but one use case, I was creating the same script over and over again and I thought it would be much simpler if there was a dynamic dispatch for resources like D1
