D1 is compatible with most SQLite’s SQL convention since it leverages SQLite’s query engine. D1 client API allows you to interact with a D1 database from within a Worker.

I mean, I don't think there is actually that much of a difference, but no, afaik there isn't a way to do batch raw queries atm

hi, I can't export my database

and there is no other way than using wrangler export

Rubi•9/7/24, 4:57 PM

oh

turns out I was having a column name called limitlimit and it's now working after I rename the table

ac•9/7/24, 6:03 PM

On a related note ^, do you all ever intend to allow exporting D1 as a simple sqlite file, rather than the complicated wrangler export (which seems pretty prone to error)? This would make local development so much easier.

I mean step one would be building a worker to handle the queries from Grafana. Then you could do it with a Grafana REST plugin

Cyb3r-Jak3•9/8/24, 3:11 AM

There is. The only thing is it is rate limited

Cyb3r-Jak3•9/8/24, 3:13 AM

Yeah you can use a REST API connetion in Grafana to query it

ah so, the return types are always js objects? so blob wil be an array of number?

Kyrre•9/9/24, 8:34 AM

Hey! Why does one D1 database consistently have ~ +80 ms query time compared to another, when querying an identical, empty table? Both run in EEUR, and both are the "production" version. None have any load.

Spuckwaffel•9/9/24, 8:59 AM

Hey there, i was wondering why when you create a Table on the CF dashboard, you cannot have multiple columns with a primary key. Is this intentional?
If you create the DB using the Console you can specify something like CREATE TABLE ... (APIKey TEXT, username TEXT, ... , PRIMARY KEY (APIKey, username) );CREATE TABLE ... (APIKey TEXT, username TEXT, ... , PRIMARY KEY (APIKey, username) ); which executes successfully.

Kyrre•9/9/24, 9:28 AM

Thanks! Any way to determine this? Or set more fine-grained location?

So strange, when the main selling point is being close to the user. Guess we have to start migrating away from D1.

o7•9/10/24, 3:43 PM

using a DB per user would be awkward to manage IMO. At that point I would use KV/DO.

storing all users in a single table/sharding the table makes more sense as you'd be able to query on every row without having to jump between DBs, especially considering the cold start times

ac•9/10/24, 6:47 PM

Yes, I mean exporting it to a simple .db file. The export from the wrangler command just exports queries, which in my experience are prone to issues if the dataset is large enough. It creates a lot of extra work, where a simple sqlite file would be amazing for dev experience

nulled•9/11/24, 4:31 PM

Hi All. Hopefully this is the right place to ask this question:

I'm working on a project where a local python app uses the cloudflare D1 REST API (via cloudflare-python) to write data to D1 as the producer.

I then use cloudflare workers to query D1 to consume this data and display it on a web app.

D1 is amazing! Everything "works" however the D1 REST API via the python app seems quite slow, perhaps hitting some type of REST API rate limit? So my next step was to batch my D1 queries in the python app to reduce round trips, same as I do in my workers. But this does not appear to be supported via the rest API? https://developers.cloudflare.com/api/operations/cloudflare-d1-query-database

The REST API spec includes "Your SQL query. Supports multiple statements, joined by semicolons, which will be executed as a batch."
Great! But how do I pass in multiple params arrays for each different query? I definitely want to be using prepared statements here for injection safety.

I could write a new worker to make a bespoke API that I send my queries and params to, and then batch them via the worker, but I was hoping to avoid another worker to maintain.

accessing D1 via the CF API is slow because it has to route to a core location. Create an API with a cloudflare worker and bind the database to the worker and it'll be significantly quicker.
