Hello, I’m Allie!•5/18/25, 4:15 PM

Sort of? You bind a DO namespace to your Worker once, but from that namespace, you pass an ID and get as many DOs as you want

One Namespace -> Many “Databases”

gruntlord6•5/19/25, 12:28 AM

yup, you can have a lot of individual objects in a single namespace

gruntlord6•5/19/25, 12:28 AM

for example, an object for every customer

gruntlord6•5/19/25, 12:29 AM

where as with D1 you need a binding for every db

Is there anyone working on a D1 client for workers with built-in retry, to try and circumvent these issues? https://github.com/cloudflare/cloudflare-docs/issues/18485

anyone here familiar or have experience in getting local D1 instances to maintain persistence during local development by chance?

Fixing D1 Local Persistence with Wrangler Pages Dev

Issue

Local D1 persistence with

wrangler pages dev

wrangler pages dev

may not work as expected, even when

preview_database_id

preview_database_id

is set in

wrangler.toml

wrangler.toml

and

--persist-to

--persist-to

is used in the

dev

dev

script. Runtime operations (e.g., API calls creating new data) might connect to a new, blank D1 instance instead of the schema-initialized, persisted one. This leads to "no such table" errors and data loss between development server restarts.

lambrospetrou•5/20/25, 7:39 AM

D1 dynamic bindings are not coming in the short-term, and still undecided for long-term. If you want to programmatically create thousands of databases, SQLite Durable Objects are already available and they are the exact same SQLite components under the hood.

Durable object is too much boilerplate.

planet•5/20/25, 2:18 PM

meh it only took less than a week to learn how to use SQLite in DO and refactor code

planet•5/20/25, 2:18 PM

you get input gates & (in my testing) much better latencies & less reads/writes because you dont need to index a user id

Ashish Rawat•5/20/25, 2:51 PM

problem is you can't query across multiple database for getting list of users, do joins and so on. So you've to use D1 for that with different concept. Cloudflare database (D1, DO) is broken. D1 has different limitation while DO has different. So basically to make everything work, you need to use both D1, DO and Queues. So instead of this, I better off go with managed postgres.

I wonder why you say this. Actually, D1 has exactly the same limitations as a single Durable Object, and even more since your worker code is remotely from the actual storage and you don't have things like transactions across queries interleaved with JS code, whereas in the DO case your code runs next to the storage and is fast. Resource limits wise, a D1 database IS a single Durable Object, so zero differences.

I assume your different viewpoint is if you design your DO architecture using per-resource/per-tenant DO vs a single D1 database, but then you are not comparing the same thing since managing multiple D1 databases in the same way would be much more complicated.

planet•5/20/25, 8:35 PM

Much less of a problem and more of a design consideration.

Personally I use D1 as a lightweight directory DBs that handles background cleanups/etc (via CRON) and login lookups. emails/sso metadata matches get logged into their SQLite in DO DB.

You also have Alarms which is part of Durable Objects (so you don't necessarily need Queues/Workflows)
You can also set up basic rate limiting in memory using

this

in each new constructor instance

This is definitely different from the messaging that I've heard from other Cloudflare folks recently, I was definitely hoping for dynamic bindings for D1 as well. It's a bit disappointing how unclear this all is.

lambrospetrou•5/21/25, 6:15 AM

This is definitely different from the messaging that I've heard from other Cloudflare folks recently

I have been in this channel for 9 months now and we never gave an ETA for dynamic bindings. It was (and still is) one of the future possible features. But, I don't want folks to start designing their new applications now depending on a feature that does not yet exist and is not going to land within say the next quarter. That's my viewpoint.

SQLite in DO's is a nice idea, but it's fairly unusable right now when you can't actually view DO instances and cannot view what is in the databases....

You cannot (yet) view them natively in the Cloudflare dashboard but there are several open source solutions to inspect your Durable Objects. For example, you could use something like https://github.com/outerbase/browsable-durable-object
I agree that DOs don't (yet) have some of the niceties of D1 like import/export but you get the flexibility of creating as many as you want much easier than with D1. So, it's about tradeoffs and what you need right this moment.

Dean•5/21/25, 7:01 AM

Yeah it truly sucks. I have workarounds for it and looking at using durable objects but think I’ll end up just using another database provider that’ll allow me to do everything d1 does but have a database for each user,

Ashish Rawat•5/21/25, 8:02 AM

Well that proves the point, neither D1 nor DO solves the basic problems completely. Why would we should use 10 different things when all can be done with postgres and postgres doesn't have 10 GB limitation.
Also this is not just the problem with DO or D1, even workers doesn't have many limitations, basically all the development products of cloudflare are just WIP and not ready for production usage completely.

lambrospetrou•5/21/25, 8:50 AM

If Postgres solves your needs, then using Workers + Hyperdrive is a perfectly fine combination. There is no need to shoehorn your architecture into the D1/DO model.

Himanshu•5/21/25, 11:30 AM

I'm unable to use D1 outside of the Workers environment. I tried in Node.js, but I'm having trouble accessing the bindings. Any solution for this?

See my link to outerbase's projects that exposes the Studio UI they have for each of your DOs. At some point we should be adding that natively into the dashboard, but until then you can use the library version.

Dynamic bindings and transactions were two things that we saw being mentioned as coming :soontm: multiple times in the past, even in official blog posts

João Castro•5/21/25, 5:23 PM

Honestly today I don't really care anymore because DOs with SQLite solve those problems so that is great

João Castro•5/21/25, 5:24 PM

Just that D1 feels like something that currently sits in a very weird spot

João Castro•5/21/25, 5:42 PM

And I have the impression that we might see something like the Functions/Pages and Workers convergence happening with D1 and DOs in the future
