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

Hello ,I was charged 1347.30 USD for D1 - Rows Read ,but the 1,342,795,529,750 mentioned in the invoice doesn't match what I saw in cloudflare dashboard ,where I can get help

Is this an expected number of errors with this number of requests? https://community.cloudflare.com/t/multiple-errors-from-worker-d1-error-network-connection-lost/710299?u=cherryjimbo

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.

gotcha - I agree. I'm in the middle of tweaking D1 support in my denoflaredenoflare tool, and it wasn't too hard to add a single one-liner subcommand for exporting a D1 database to a local sqlite DB file: denoflare d1 export-db your-database-name --file /path/to/downloaded.dbdenoflare d1 export-db your-database-name --file /path/to/downloaded.db

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.

you should probably use r2 or images and store the link in d1, storing directly in any db takes a lot of storage, and in d1 being limited to 10GB doesn't seem like a good idea

You should probably run in fewer statements, each inserting more than one record. A few requests inserting more than one item will be more efficient than many requests all inserting one item.

I have a bunch of data in a mongo install that I want to move to D1.

oof2win2•9/13/24, 9:36 AM

use jsonb. you can create indexes on expressions so you can essentially index say a userid field on a json (or something deeply nested as well)

oof2win2•9/13/24, 9:36 AM

jsonb because it is stored better and performs better, but even normal json has the ability to be indexed

Do you mean an UPDATE trigger that updates a timestamp on a table each time you sent an UPDATE to some table? If so I've been using exactly that for as long as I've been using D1

CREATE TRIGGER trigger_name AFTER UPDATE ON table BEGIN UPDATE another_table SET timestamp=UNIXEPOCH('NOW') WHERE column=some_val; END
