Ah yep - remove the BEGIN TRANSACTION;BEGIN TRANSACTION; and the end of it, we're already running in a transaction for you (i'll also update the docs to mention that)

wesbosOP•2/28/24, 8:38 PM

Maybe im doing this wrong - I have a local wrangler D1 DB, I ran that dump command on the sqlite DB directly, but is there a wrangler command to push my local DB up to production? Or a command to export

Max (@rozenmd)•2/28/24, 8:39 PM

That is a good point though - wonder if we can't make wrangler take the local db and do that for you

wesbosOP•2/28/24, 8:45 PM

took the transaction stuff out and still hitting it. Will dig and se if there are any other lines

can you query d1 from outside a cloudflare worker?

matt•2/29/24, 12:05 AM

thanks @geelen for my use case I have a kafka topic that I want to consume from & then write results to d1. I guess my best option is to run a cloudflare worker on a cron trigger every 1 minute to consume, process & write to d1

matt•2/29/24, 12:18 AM

so this is coming off the back of a realtime streams system (bytewax) so I guess I would create a new flow that pulls from the kafka topic and then writes to d1

matt•2/29/24, 12:19 AM

and then deploy it onto my k8s cluster. im building a zapier-like system so d1 would be one of the potential places where data is exported

matt•2/29/24, 12:21 AM

I think I might do that, then it'll also reduce the coupling between the service & the cloudflare environment as it'll just need to know url + api key

matt•2/29/24, 12:22 AM

i think i might avoid cron as there's a chance in future i need to work on making this ultra-low-latency

Max (@rozenmd)•2/29/24, 12:42 PM

D1 is built to work to the strengths of Cloudflare's network, so we can't offer extremely large databases while also loading them quickly. It's significantly easier for us to offer millions of DBs with a size limit instead.

The limit is currently 2GB and we're working towards making it 10GB - but D1 will require a change in how you think about your project's data if you're looking to build a big platform. Instead of storing all of your data in a single DB, you would store each customer's data in their own DB (and we're building tooling to make it easier to dynamically access multiple DBs in a single Worker without redeploying)

The weird thing is that the error was returned, but the delete succeded.

KJolibois•2/29/24, 4:14 PM

I'm working on d1 to build something out with a friend, I added him to my account (e.g kj@emailprovider.com) and gave him (e.g kfriend@emailprovider.net) workers permission for all domains. At first he could not see the databases when logged in, whenever he clicked on d1 it kept sending him to the overview page. After I sent him a link to the page I was using (eg https://dash.cloudflare.com/{D1-ID-HERE}/workers/d1) he was able to see the database, but the account name on the top left changed from his email to mine. We were able to collaborate just fine. There was probably a step we missed where he needed to change over from his default account to mine ,but I thought I should ping just in case it was unexpected behavior. Thanks for all the great work on d1. I'm loving it so far .

Tony Leung•2/29/24, 4:26 PM

but not all of it right? I guess that you are batching a lot of DELETE commands, not delete by ID. According to the document, I think cf implements batch using a loop, trying to find a gap between other queries to run commands. If the batch does not success after a period of time, it will flag the batch as overloaded and returns the failed command index (as shown on the batch array). Since queries are run sequentially and commit on each success one then that's why your batch failed but some of them are executed.

Tony Leung•2/29/24, 4:27 PM

As a mysql user, on some large delete execution plan, i tend to select all the record ID which I want to delete first then delete by ID later

TTony Leung but not all of it right? I guess that you are batching a lot of DELETE commands,...

itsmatteomanf•2/29/24, 4:28 PM

So, afaik, batches are transactions behind the scenes, so either they all run or none do.
In any case, here, I was doing a DELETE FROM table WHERE datetime < datetime('yyyy-mm-dd')DELETE FROM table WHERE datetime < datetime('yyyy-mm-dd'), single query.

Tony Leung•2/29/24, 4:29 PM

do you index the datetimedatetime row?

TTony Leung do you index the `datetime` row?

itsmatteomanf•2/29/24, 4:29 PM

Yes, of course

Iitsmatteomanf Yes, of course 🙂

Tony Leung•2/29/24, 4:30 PM

oof so your table must have a million rows XD

TTony Leung oof so your table must have a million rows XD

itsmatteomanf•2/29/24, 4:30 PM

The table was actually 10M, before the deletes, which I did in 14d groups, to avoid too much overloading, but wasn't enough sometimes apaprently :lul:

TTony Leung oof so your table must have a million rows XD

Tony Leung•2/29/24, 4:32 PM

it reminds me of one time I tried to execute 10 or 20 query like that on a mysql table which has 300m rows. The production was down shortly after, the db was not responding . I was using aurora serverless v1 so there is no way to reboot the DB. It hangs for 8 or 9 hrs and costs me about 200 - 300$

Tony Leung•2/29/24, 4:33 PM

Tony Leung•2/29/24, 4:33 PM

I don't think a cluster of oracle DB could handle that...

TTony Leung oh...

itsmatteomanf•2/29/24, 4:36 PM

To be fair, I was told to go ham on it and it does sustain 1000 write queries per minute, along with 100 read queries per minute. Optimized queries, most are single or a few rows each, but still.

could it be this at the start too? ```sql BEGIN TRANSACTION; CREATE TABLE _cf_KV ( key TEXT P
