How do I apply migrations on my production database? To apply local migrations, I just run:

bun wrangler d1 migrations apply db_preview --local

bun wrangler d1 migrations apply db_preview --local

bun wrangler d1 migrations apply db_preview --local

bun wrangler d1 migrations apply db_preview --local

This is a SvelteKit pages app.

And my wrangler.toml if needed:

[[d1_databases]]
binding = "DB"
database_name = "db_preview"
database_id = "db_preview"
migrations_dir = "./drizzle"

Hi, Is this compatible with remix+vite?　https://developers.cloudflare.com/d1/examples/d1-and-remix/

Yes, that works with remix+vite. I found that it’s not necessary to specify the bindings in the command line when running locally. Just let ‘remix vite:dev’ pick them up from wrangler.toml and include the local bindings in the wrangler.toml. I put together the cloudflare example for ‘remix-auth-totp’ that uses drizzle with d1 that has the local bindings in wrangler.toml. https://github.com/mw10013/remix-auth-totp-cloudflare-example

wait so local development and remote development (in this scenario) return different results ?

i knew that it was fixxed, but I would not deploy to prod without proper testing locally.

Max (@rozenmd)•3/25/24, 8:55 AM

D1 is built to work to the strengths of Cloudflare's network, so we can't offer extremely large databases while also loading them quickly. It's significantly easier for us to offer millions of DBs with a size limit instead.

The limit is currently 2GB and we're working towards making it 10GB - but D1 will require a change in how you think about your project's data if you're looking to build a big platform. Instead of storing all of your data in a single DB, you would store each customer's data in their own DB (and we're building tooling to make it easier to dynamically access multiple DBs in a single Worker without redeploying)

Aim Salam•3/25/24, 8:58 AM

Thank you for the response. I'm very excited what D1 can do in the future. I'm looking forward to it

Max (@rozenmd)•3/25/24, 8:59 AM

also if you want to stick to the old model (one single big db), we have Hyperdrive for that: https://developers.cloudflare.com/hyperdrive/

itsmatteomanf•3/25/24, 5:58 PM

The biggest limit here (but I know you are working on it, so hopefully soon it gets fixed) is that you can't dynamically connect to a database.
If I have millions of users, how can I configure a database per user (if I can work around the limits that cross-user queries are impossible, at the moment) and reach it via Workers?

kenton•3/25/24, 6:10 PM

The way you are imagining it works is the way D1 v1 and v2 worked... which turned out to be way too slow. In v3 we pull the full database down to local disk upfront.

AAaronO Did v1 and v2 use the local disk as cache too ? In the limit, eagerly pulling th...

kenton•3/25/24, 6:19 PM

I believe pages were actually cached in RAM (which is why the database size limit was 100MB). I wasn't closely involved with v1 or v2 though so can't comment in that much detail.

kenton•3/25/24, 6:20 PM

v3 is based on a new storage engine which I described a bit here: https://twitter.com/KentonVarda/status/1659551757796515846

So I've spent the last ~three months writing a new distributed storage engine based on SQLite and it has been FUN!

This DB-per-user vision is very exciting to me and very relevant to my application. I know D1 GA had been mentioned to be coming up soon (this or next month). Is this "sharding" of databases further out than that, and not something we should bank on anytime soon?

I'm actively working on migrating my application to D1 and wondering if sharding is something I can be planning for now as I migrate.

RexNormous•3/27/24, 3:35 PM

Interesting... that unfortunately seems like a lot of separate migrations to worry about

My unhelpful 2 cents is that it's be awesome to have selecting db instance be like choosing a Durable Object to interface with, e.g.: env.DB.getByShardKey(id: string)env.DB.getByShardKey(id: string). Then all DB's under that shard key would share a schema, get the same migrations, and effectively be "grouped' together, if that makes sense.

RexNormous•3/27/24, 3:40 PM

This is really awesome - didn't realize this existed.

Picturing my user's sign up flow though, I'd effectively need to pause a user's sign up and go into a "setup phase" for them (when a new deployment kicks off, db is created, etc.), then email them when we've "provisioned" their account. I think this would work if my app was invite-only & in beta, but unfortunately my app is on-demand and self-serve.
