I am working on python application - can we use python connect d1 db?

Probably though the REST api. https://developers.cloudflare.com/api/operations/cloudflare-d1-query-database

If you need performance, write a Worker then talk to it over HTTP from python

Hi, I am running wrangler pages dev --compatibility-date=2023-01-01 ./pages --kv=KV --d1=DBwrangler pages dev --compatibility-date=2023-01-01 ./pages --kv=KV --d1=DB and it cannot find my table, I have assumed the d1 binding is to my remote database? is this not the case?

andyt•10/10/23, 6:58 PM

ah ok, how do you create a local d1 database and script it?

Cretezy•10/10/23, 9:05 PM

Why is the D1 HTTP API lower performance than the API in Workers? (excluding that it's not in the same datacenter)

Cretezy•10/10/23, 9:10 PM

That's the "(excluding that it's not in the same datacenter)" part, but it seems like the API is quite slow, even for remote

Cretezy•10/10/23, 9:12 PM

I'm seeing 500-700ms for simple queries

Max (@rozenmd)•10/10/23, 9:12 PM

The API isn't designed for Workers-style access patterns, it's an API

Max (@rozenmd)•10/10/23, 9:13 PM

whereas a Worker will be within 50ms of 95% of the internet-connected world

Cretezy•10/10/23, 9:15 PM

But why isn't it designed for this? Multiple queries in a Worker is <100ms, a single of those queries outside is >500ms. They are designed for Workers, but the API being 5x slower seems like a missed opportunity

Cretezy•10/10/23, 9:15 PM

The alternative is making a query worker such as http-api-d1-examplehttp-api-d1-example above, but it feels like the API should be able to do that

This, and also the core datacenter might be distant from the D1 location, which adds to the roundtrip time.

itsmatteomanf•10/10/23, 9:27 PM

You are generally close to the database you create, so it's fast you -> worker -> db.

itsmatteomanf•10/10/23, 9:28 PM

If you use the API you do you -> api (possibly far away) -> worker (it's an assumption, but I bet it's a worker or similar) -> db (close to you).

itsmatteomanf•10/10/23, 9:29 PM

This makes queries at least 4x the time to go from you to the API, plus inefficiencies as connections need to be established.

Max (@rozenmd)•10/10/23, 9:42 PM

this, we built an API rapidly with what we already had, we might evolve it in the future but that's what's there today

Paul•10/10/23, 9:46 PM

Any guis work with D1 for viewing live data?

Paul•10/10/23, 9:47 PM

(It seems I can use dbeaver for viewing the local SQLite file)

There is a console in the dashboard

Are you able to run arbitrary queries from the dashboard?

Yeah. Go to your D1 database in the dashboard and there will a tab of ConsoleConsole

Ok great. Is there a plan to support more traditional non web based clients

Cyb3r-Jak3•10/10/23, 10:24 PM

Personally, I wouldn't expect any official support given that D1 would only be queryable over HTTP but people from the community might add support to the various projects

Hello, I’m Allie!•10/10/23, 10:43 PM

Is HTTP even officially supported? I know it is wrangler, but I forget if it is documented

Yeah

anyone using SvelteKit managed to get npm run devnpm run dev working after adding D1? I'm assuming we would need to tell it to run the local db

Fabian•10/11/23, 1:51 AM

How to select the most recent day's data from the database?
The database content is as follows:
id ip UA time
41 139.162.86.143 Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/117.0.0.0 Safari/537.36 2023/10/7 09:40:22

Can this be done?
SELECT * FROM m_table
WHERE time >= DATE_SUB(NOW(), INTERVAL 1 DAY);

use API

MMax (@rozenmd)If you need performance, write a Worker then talk to it over HTTP from python

MrXOOP•10/11/23, 2:56 AM

so we will use python -> call HTTP request to worker -> worker handle d1 db logic?

MMrXO use API

Fabian•10/11/23, 2:57 AM

大佬帮看看吧

MrXOOP•10/11/23, 2:58 AM

like this

curl --request POST \
--url https://api.cloudflare.com/client/v4/accounts/account-identifier/d1/database/database-identifier/query \
--header 'Authorization: Bearer undefined' \
--header 'Content-Type: application/json' \
--data '{
"params": [
"firstParam",
"secondParam"
],
"sql": "SELECT * FROM m_table

}'

I had a look and it does not seem to have models? It seems only to create data rows rather than instantiate classes.

add RETURNING *RETURNING * to the end of the query

or RETURNING idRETURNING id just for the id column

andyt•10/11/23, 8:55 AM

I have setup my local D1 using wrangler and --local, I have inserted a row and can retrieve the row using wrangler execute, when I run my function I get Error: D1_ERROR: no such table: companyError: D1_ERROR: no such table: company, I have my D! config in my toml file and when I run my pages I pass --d1=DB--d1=DB which matches the binding name in my toml, what have I done wrong ?

MrXOOP•10/11/23, 9:02 AM

took 0.2s to insert a row via API, so slow

MrXOOP•10/11/23, 9:02 AM

maybe I need use worker

MMrXO maybe I need use worker

itsmatteomanf•10/11/23, 9:02 AM

This, yes.
