Currently you can't. Dynamic bindings are on the roadmap.

Larry•12/9/24, 12:28 PM

Have you explored using Cloudflare Durable Objects (DOs) with the SQLite API? They provide a workaround for the current lack of dynamic binding for D1. One DO per customer is a common pattern.

Thanks, I was looking into that, but so far the limit is 1 GB and not sure how to ensure data backup yet

The 1GB limit is while in Beta. It will match D1's 10GB once it goes GA.

Larry•12/9/24, 7:28 PM

Offline backup is a lot harder. You will just have to trust Cloudflares time travel capability, which is not super reassuring, or roll your own.

pricing is drastically different on a read-heavy workflow (specially indexed), also includes a much higher monthly allowance on usage for workers paid

Burrito•12/10/24, 2:05 AM

I'm under the impression that DO SQLite has the same pricing as D1? Unless you are talking about the extra cost of DO itself.

Ian•12/10/24, 2:13 AM

DO SQLite AFAIK uses DO pricing, each read and write

Ian•12/10/24, 2:14 AM

Do let me know if this is not true

Burrito•12/10/24, 2:14 AM

There are two pricing models for DO, there's the KV storage backend and the SQLite storage backend. For the SQLite storage backend, pricing model is the same as D1.

Ian•12/10/24, 2:16 AM

Thanks, I had to do a full search of the docs to find it

Ian•12/10/24, 2:17 AM

If this is the case, then I have nothing more than to wait for 10GB storage limit per DB

sor4chi/monica•12/10/24, 3:52 AM

Hello. I have a question about D1.

Even for a very simple query like “SELECT 1”, the database latency takes around 500ms. This number is confirmed using serverTiming, so I’m certain it’s not caused by other factors outside D1.

Additionally, I have confirmed that several people in the X community are experiencing the same issue. I tested this by sending requests to Workers with D1 binding from the Tokyo area.

If anyone else can reproduce this, or if you know the cause or any solutions, I would greatly appreciate your input.

lambrospetrou•12/10/24, 9:18 AM

Where is your database located? Usually network is what takes up the whole time when querying D1.
The meta.durationmeta.duration field should tell you how much the actual SQL query takes when running inside your database.
Everything else is networking to get from your Worker location to your D1 database location.

This is not to say there aren't things to improve internally (there are!!), but if worker and database are far away, then hundreds of ms latency is to be expected.

sor4chi/monica•12/10/24, 10:18 AM

Hi, @lambrospetrou
Indeed, when fetching the meta, it appears to be the case. This suggests that D1 itself is not hopelessly slow.
Does this mean that D1’s location selection strategy is the issue?
As a user, is there any way to intentionally select the location other?
Smart placement didn't work.

lambrospetrou•12/10/24, 10:34 AM

Unfortunately, region-wise location hints are the only way to influence its location at the moment. In certain regions this is still a very wide area though, indeed. For example, APAC can be anywhere between Singapore and Osaka (https://where.durableobjects.live/region/apac).
I can't promise anything on this yet, but it's something we are thinking on how to improve.
Read replication will definitely help with reads on this depending on where your queries originate, but writes are going to still be impacted.

For now, if your servers/workers are in a single location (e.g. Tokyo), try creating one a few times and see if you get one close to you.

lambrospetrou•12/10/24, 10:42 AM

After creation the database doesn't move no. The first query is always going to be slow since you are cold starting your database, its location being cached in Cloudflare's CDN etc.

sor4chi/monica•12/10/24, 10:44 AM

Thank you, I understand now.
I apologize if my understanding is incorrect, but I had heard that D1 delivers “read replicas to the edge,” so I assumed that READ operations would be reasonably fast regardless of the location.

lambrospetrou•12/10/24, 10:54 AM

Read replication is coming soon yes, but it's not rolled out yet.
Even with read replication though, you are still going to go over the network on a different machine, or location even, so it's not going to be a single-digit millisecond solution either (it cannot be due to physics!).

o7•12/10/24, 12:24 PM

I know promises cant be made, but would this essentially just consist of a finer control for location hints?
e.g. when dynamic bindings arrive, and I create a DB for each client, I can ensure the DB spawns in as close as possible to them. Instead of randomly getting a DB handed to you in a random city.

This would be amazing especially if R2 matched this behavior when doing D1 + R2 writes together, which would improve performance by a lot...

for pure query duration? seems pretty slow - does your WHERE clause hit your index?

Original message was deleted

lambrospetrou•12/10/24, 3:10 PM

How are you measuring this duration? How much data are those rows?

Original message was deleted

lambrospetrou•12/10/24, 3:14 PM

Couple hundreds rows, but how much data? 200KB, 2MB, 200MB?

Original message was deleted

lambrospetrou•12/10/24, 3:14 PM

So this is from your worker code, not the meta.durationmeta.duration field of the D1 response, right? If yes, tens of milliseconds is expected.
If you want to see the actual SQL query duration check the meta.durationmeta.duration field.

Original message was deleted

Max (@rozenmd)•12/10/24, 3:18 PM

Yeah meta.durationmeta.duration tells you how long it actually took - anything else gives you network noise

Original message was deleted

Max (@rozenmd)•12/10/24, 3:22 PM

meta.durationmeta.duration measures how long sqlite took to actually get your data

measuring from your Worker includes time it took to reach D1's Worker, time for D1's Worker to reach the DB, and back

In short, meta.durationmeta.duration is all you can actually influence (apart from enabling smart placement, I guess)

I found drizzle has just enough edge cases to not trust it, and just stick to raw sql.

I do use drizzle to generate migrations and then do custom type casting w the drizzle schema definitions I make.

CedricHadjian•12/10/24, 4:12 PM

Hi peeps, we got a table that has 12,000,000 rows and we're facing this error:

D1_ERROR: D1 DB is overloaded. Requests queued for too long.

This is the query that we're running:

SELECT query, COUNT(*) as occurrences FROM queries GROUP BY query ORDER BY occurrences DESC LIMIT ?;

We're passing a limit of 10 and still getting this error, what can we do to bypass the error?

zod

or similar because it enforces exact 1:1 match between types and actual output share versus types drifting away from the actual type

Isaac McFadyen•12/10/24, 10:53 PM

IMO it's better to have an error thrown from type mismatch than have types that aren't actually correct
