Hi, I've just discovered Outerbase Studio from the recent Acquisition announcement, it's great news

Hi, I've just discovered Outerbase Studio from the recent Acquisition announcement, it's great news to see it become part of CloudFlare. I was thinking about implementing it in a project I'm working on, but I found that the license is AGPL which prevents me from doing that without making my codebase public. Since the original cloud offering is now closed for new users and sunsetting soon, and seeing that the original repo is no longer active, would it be possible to make the license less prohibitive ?

I was thinking about implementing it in a project I'm working on

Do you mean using the Outerbase Studio with your D1 databases, or do you just want to use it in a completely different project unrelated to D1? Just clarifying since this the D1 channel.

aliendevOP•5/27/25, 11:36 AM

I want to make it part of my hosted dashboard, so that my users can access and edit their own DBs, which are all part of a single multi-tenant D1 database (and the project itself will be deployed using CF workers).
so to answer your question, my use case is for a different project, but related to D1 and fully part of the CF ecosystem.

Hi everyone, I have a 3gb database with multiple keys (one line can be quite large - a few kb - but the blobs are not part of any keys), the maximum size is 10gb, but for some reason querying even this small DB is very slow (even simple queries take up to a minute). I use composite keys. Anybody else seeing this type of behavior? Noteworthy is the fact that this db experiences a lot of writes as it is a live stats marting table.

If you are doing an export the whole DB is blocked until it uploads everything to R2. If you want to abort the export, then unfortunately you need to stop polling and wait a few seconds for it to stop.

lambrospetrou•5/28/25, 3:42 PM

What is the

.meta

.meta

information telling you about the duration of the query itself? 1 minute is very long either way and probably hints to other issues, commonly overloaded DB due to traffic or slow-ish consecutive queries.
Also, are all your queries slow, or just that specific one?

Paul Mihai•5/28/25, 3:42 PM

Writing seems to be perfectly fine, but querying especially on high writing load is suuuuper slow

Paul Mihai•5/28/25, 3:43 PM

we have a few million writes / day

PPaul Mihai Writing seems to be perfectly fine, but querying especially on high writing load...

lambrospetrou•5/28/25, 3:43 PM

Keep in mind that D1 is single threaded. Only one query executes at a time.

Paul Mihai•5/28/25, 3:43 PM

but just a few reads a day

Paul Mihai•5/28/25, 3:43 PM

so the problem may be the queue

Paul Mihai•5/28/25, 3:43 PM

because we have so many writes?

PPaul Mihai so the problem may be the queue

lambrospetrou•5/28/25, 3:44 PM

Yes, maybe. Check the

meta

meta

field of the responses for the duration listed. If that's small (a few milliseconds) then the issue is not the query itself. It can be either the volume of your load (number of requests and time each write query takes to finish) or some networking issue. The latency of the query is also available in the UI and through wrangler insights.

Paul Mihai•5/28/25, 3:45 PM

I'll do that! Thanks! Also I understood there is a "new" version of D1?

Paul Mihai•5/28/25, 3:46 PM

is that still a thing or were all migrated to the new backend?

Spencer•5/28/25, 3:46 PM

but i am not polling atm, it's just stuck, there is a way to cancel the process somehow ?

lambrospetrou•5/29/25, 10:30 AM

You probably mean a new version of Durable Objects, not D1. The SQLite based DOs are new-ish yes, but D1 was already built ontop of those. There is no new version of D1.

Zig•5/29/25, 6:36 PM

Im running a pages app with D1 locally, and a DO thats accessed through both a DO binding in pages and a separate worker for the DO thats sometimes called by pages. The DO worker is ran with wrangler persisting the state to the pages worker D1 instance. The pages worker calls the DO to do some work and it modifies D1, the DO sends web socket messages to pages occasionally as it runs forcing pages to fetch D1 data.

I am getting seemingly random SQLITE and D1 errors that appear in random order, and arent confined to any one section of my code. Is this just a byproduct of trying to use 2 instances of wrangler, one with the persist-to flag on local environments? Or is this indicative of a problem with my usage patterns? Will this still happen on deployed instances?

Zig•5/29/25, 9:45 PM

Update: Deployed version works flawlessly. Guessing its some issue with 2 wrangler instances trying to use the D1 file at the same time

lambrospetrou•5/30/25, 3:19 PM

We released some improvements to the D1 REST API a few days ago and now most endpoints should have some speedup. The query endpoints especially now should be much faster if you are outside the US.

Read more in the changelog: https://developers.cloudflare.com/changelog/2025-05-30-d1-rest-api-latency/

Would love to see if anyone notices this in their graphs.

lambrospetrou•5/30/25, 4:25 PM

Yeah there is a bit more work to do there, but if you have high traffic going through a worker is still best. REST API has the rate limiting, still needs to do auth, check your plan status, etc, so it will always have some delay even if rate limiting was higher. But yes, rate limiting is a common issue with the REST API. It's a thing folks want to improve across CF overall.

Not at the moment, unfortunately, you will have to make sure all queries going through are read only.

gruntlord6•6/5/25, 2:38 PM

could you have a worker in the middle that prevents writes from being passed?

gruntlord6•6/5/25, 2:38 PM

alternatively you could download the d1 export and spin up a local sqlite database

dsds10•6/5/25, 7:57 PM

Regarding the 50k db (soft) limit, how likely is this limit to be increased for non-enterprise customers?

davidbarratt•6/7/25, 12:55 AM

can you dynamically bind a D1 database? I'd like to have a database per-tennat that gets selected based on the request, but it doesn't look like that is posible without just using the REST API directly? Is that right?

You'll probably need a bit more boilerplate than with D1 but its a far better solution overall

hmm that's interesting. somehow I had the "sqlite in do" stored as "ephemeral" in my mind, but checking the docs that's not the case. I also read that the max size in DO was 1GB, but this doesn't seem the case anymore (or never was)

what are the pro/cons of using sqlite in DO vs using D1?
