Good to know. I guess I'll enjoy D1 while I can. If this is a limit that Cloudflare can adjust individually, is there any way I can check to see if that's what's going on in my case?

Is this a brand new database or did you create it during early alpha?

Curtis Jones•10/9/23, 4:23 PM

I can confirm the same results you got with that test. However, a "real" query on my db that uses LIKE (with a 98 byte string) fails with that error while the GLOB equivalent succeeds. I'd very much like you to not fix this bug, so please disregard.

kianOP•10/9/23, 4:35 PM

I don’t think it’s a bug in D1 - D1 doesn’t enforce the limit itself, it just tells SQLite to do it. Maybe SQLite is optimising your pattern under the limit? I’m not sure.

kianOP•10/9/23, 4:35 PM

In any case, I wouldn’t consider it a bug.

David•10/9/23, 6:10 PM

Since today rows_written and rows_read is always 0 and the sql action wont get executed when running with "EXPLAIN QUERY PLAN". I have changed nothing in my code and it worked perfectly fine 2 days ago. Anyone else experiencing this?

Currently we are on mongodb and everyday we insert 20k rows to the db. On mongodb we insert them all together as a table and it parses it. How can we mass insert rows on D1 all together in order to avoid spaming 20k requests.

Hi, can we use this outside of workers? Since currently the db is managed by python code running in our servers.

No clue

afaik the only documented usage of D1 is through workers

Is it subject to the 1200/5 min limit of the API generally?

kianOP•10/9/23, 8:33 PM

iirc there's a few APIs with their own limits - I guess if D1 ends up being popular enough to use outside of a Worker then that might be an option, but I suppose that might be directed to setting up your own API w/ a Worker

It’s an example: in practice, those values will be user provided and so you always want to use a parameterized query for security.
