seems fine to me. one thing drizzle doesn't support D1 replication so take that in consideration if you want to use that.

If you’re just starting the project would recommend using the drizzle beta which should be stable in 1-2 months. Saves having todo a big refactor later when you decide to upgrade to v1

QQ. on the Queries overview for D1: are the "Rows Read/Written" the total for the "count" number of requests? Or average values? I'm trying to understand how those number can be mapped to the numbers given at the top of that page. Because there I have 30M rows read. And I wonder how come I would reach that number, given the top four requests are only in the thousands. And there's not that huge tail with millions of smaller queries.

lambrospetrou•9/10/25, 5:43 PM

Are you getting these in some specific location? There isn't any service wide issue at the moment. There was a blip of network issues for 1-2 minutes in eeur for a tiny % of requests, from what I see.

Llambrospetrou Let me clarify with the team and get back to you.

lambrospetrou•9/10/25, 5:46 PM

Currently the column Rows Read is using averages, so 45.6K*662=30M45.6K*662=30M, which matches what you said. We should probably make that sum as well, but it might confuse folks with the count in that case.

lambrospetrou•9/10/25, 5:48 PM

Replication shouldn't cause this. Maybe your errors were from the replica in eeur during that blip of errors?
If you continue seeing consistent errors let us know (account+DB IDs, and some rough timerange).

lambrospetrou•9/11/25, 7:22 AM

Yeah, please do if you are still seeing these.

Mukesh•9/11/25, 7:28 AM

I have a use case where I need to connect my D1 database from outside worker, is there possibility to do that?
I searched on google but no luck.

lambrospetrou•9/11/25, 2:15 PM

Hey folks, for those that don't read changelogs, we documented the automatic retries we do for read-only queries. https://developers.cloudflare.com/changelog/2025-09-11-d1-automatic-read-retries/

This has been asked many times over the past few months, so we rolled out our first iteration in the past few weeks.
Read only queries are now retried automatically when the errors are retryable, so your app code should mostly retry idempotent write queries that you deem necessary, or if you want more than two retries that we are doing.

Read the changelog for the full details.

D1 automatically retries read-only queries

D1 now detects read-only queries and automatically attempts up to two retries to execute those queries in the event of failures with retryable errors.

Silvan•9/11/25, 2:26 PM

damn i just implemented auto retry it all my d1 projects

but nice change

Jun•9/11/25, 2:35 PM

Application-level retries are still recommended for idempotent queries (https://developers.cloudflare.com/d1/best-practices/retry-queries/)

Silvan•9/11/25, 4:43 PM

oh is that page new? never saw it before but good to know

Ehbraheem•9/11/25, 10:45 PM

lambrospetrou•9/12/25, 6:57 AM

Fair question we did think about. Short answer is that it should not happen in practice, although in theory it is possible.
There is a very rare case that attempt 1 executed on the underlying database, published stats about rows read/written, and then the response failed to be returned back to our D1 worker (what your code is calling through the D1 worker binding), so the worker will retry the query.
In our experience with the errors we see is that the vast majority of them is literally not even reaching the database in the first place (or failing before start execution), and the retries are meant to solve that problem mostly in case of transient errors. Also, if the response failed to come back to us, probably the retry will fail too since it is probably a network issue.

I haven't notice this being an issue in a few accounts I have been spot checking over the past few weeks, but please, if you do notice in your case some billing issue, let us know. We are still monitoring the retry success ratios and considering more improvements to do over time, so any feedback is welcome.

Remember, D1 is not billing on requests, but on actual rows read and written successfully.

I will ping the team about this. Is the beacon_minorbeacon_minor column newly added through the Studio or did it exist before you made changes through the Studio UI?

I see. Trigger editor support is also on our roadmap for this month. Glad you figured it out! We’ll continue improving the studio experience, and please feel free to share here if you encounter any issues or have suggestions for specific areas of improvement.

There is a Studio (SQL browser) interface inside of Cloudflare for D1. Click the blue "Explore data" button when inside a D1 instance, or the "..." menu next to an item in the resource list page when you first click D1 from the sidebar.

HI Team I'm prototyping some very simple database running sql queries manually, it seems that on safari if the sql is long enough it overflows and the screen is not scrollable so i can only see the top part of the query itself not even the result.

blyedev•9/14/25, 10:11 AM

To be more precise only the summary is not scrollable the query result is perfectly fine. I think the query I executed may have resulted in an error as well, if that's relevant

Hello

The d1 pricing is based on rows read and write.

What if I read something but it does not result in any row (no row exist for that query in the db)

Will it be counted in the billing ???

maj•9/14/25, 11:16 AM

How are the SQL lower()lower() and upper()upper() supposed to work with non latin or accented characters? select lower('Édith Piaf');select lower('Édith Piaf'); returns "Édith piaf" - which obviously isn't lower case. Therefor many of my exact searches fail.

Isaac McFadyen•9/14/25, 1:21 PM

What if I read something but it does not result in any row (no row exist for that query in the db)

Rows are still read to search for that row, so yes it will count.

Isaac McFadyen•9/14/25, 1:22 PM

Either a full table scan (which you should try to avoid as it reads every row and is also slow) or an index read (which is billed like a row read)

Isaac McFadyen•9/14/25, 2:10 PM

It's going to heavily depend on your queries and DB schema so we won't be able to give a concrete answer, you'll have to make the queries and check the metrics D1 returns.

Rows retrieved has nothing to do with rows read.

JJames Rows retrieved has nothing to do with rows read.

Sb•9/14/25, 5:43 PM

So, doesn't it make the system little negative?

Because, to find the rows to be retrieved.
It must scan all the rows (read all the rows to see if they are valid for the query )

And it will exponentially grow the billing as the db grows.

Am I correct?

Isaac McFadyen•9/14/25, 5:47 PM

It does not scan all the rows if you have an index on the rows.

Isaac McFadyen•9/14/25, 5:47 PM

In that case only the index will be searched (much fewer rows read)
