I would love to integrate D1 with kysely, according to the author of kysely-d1, integrating with the batchbatch API is not feasible for this

Transactions support · Issue #2 · aidenwallis/kysely-d1

Transactions are not currently supported in D1. Once they are, this package needs support added for them.

Hi all, is there a way to restore a D1 from a backup? I have 2 databases - one has some data and the other is empty. I am trying to copy all the data from the first to the second. I was hoping that I could export a backup from the first one (which I was able to do) and then use the restore on the second (and hope to 'clone' the first it into the second - including structure and data)

cloudflare has built in backups on experimental backend.

Thanks! I'll have a look. I knew about the Backup function, I just could not find the Import from an external backup.

wrangler.toml

wrangler.toml

, why do we need to specify

database_name

database_name

? it seems redundant, given that you specify the database ID

(could also be a question for #wrangler , just lmk and ill move this over there)

Max (@rozenmd)•7/25/23, 4:19 PM

it probably wasn't well thought out tbh

Max (@rozenmd)•7/25/23, 4:19 PM

much like how we have envs in wrangler.toml but also preview_database_id

kian•7/25/23, 4:32 PM

At least D1 doesn't error if you don't specify a

preview_

preview_

:^)

Kkian At least D1 doesn't error if you don't specify a `preview_` :^)

Hyper•7/25/23, 7:02 PM

yeah with r2 i had to specify a preview for any env that is not at the top level configuration of wrangler.toml

Hyper•7/25/23, 7:02 PM

which i just set to be the same as the top level bucket anyway

kian•7/25/23, 7:05 PM

Yeahhh, it's not the best

micromashorOP•7/25/23, 11:15 PM

ah I see

micromashorOP•7/25/23, 11:29 PM

wow the beta backend is incredibly fast compared to the alpha backend

James•7/25/23, 11:49 PM

new D1 backend be zoomin' yeah, it's such a wild improvement

micromashorOP•7/26/23, 12:27 AM

yeah I did a double take because I thought they just changed the units in wrangler from

ms

ms

, but no, the query really did only take 0.3ms

micromashorOP•7/26/23, 2:00 AM

does

stmt.raw()

stmt.raw()

return an empty array or null if there are no results?

wangtiezhu•7/26/23, 3:21 AM

same question. I am very much looking forward to the day D1 officially launches.

turns out native code is faster than WASM

DDenys Question: how can I specify binding name other than default when creating D1 dat...

Max (@rozenmd)•7/26/23, 11:14 AM

update your wrangler.toml to be:

[[d1_databases]]
binding = "MY_DB" # i.e. available in your Worker on env.DB
database_name = "...."
database_id = "..."

[[d1_databases]]
binding = "MY_DB" # i.e. available in your Worker on env.DB
database_name = "...."
database_id = "..."

DDenys @rozenmd Thanks ... I was thinking about that ... will it work on Cloudflare sid...

Max (@rozenmd)•7/26/23, 11:16 AM

in Pages you'd have to configure the binding via the Cloudflare dashboard

Tony Leung•7/26/23, 11:45 AM

Hi guys, has the new D1 engine had backup feature?

Tony Leung•7/26/23, 11:45 AM

and is it stable enough to not losing data or failed unexpectedly?

Max (@rozenmd)•7/26/23, 12:01 PM

You can now roll your database back in time up to 30 days - we're still in alpha though.

Tony Leung•7/26/23, 12:08 PM

thanks

Tony Leung•7/26/23, 12:11 PM

the old D1 engine works pretty well for me! Should I expect the same consistency with D1 new engine?

Tony Leung•7/26/23, 12:12 PM

and is there anyway I can restore database from a local backup?

Max (@rozenmd)•7/26/23, 12:16 PM

you can expect a performance improvement, here's what we noticed:

TTony Leung and is there anyway I can restore database from a local backup?

Max (@rozenmd)•7/26/23, 12:17 PM

you'll need to dump the local backup to sql first: https://developers.cloudflare.com/d1/learning/importing-data/#converting-sqlite-database-files

is it possible to get the query output as csv in wrangler?

NNoel is it possible to get the query output as csv in wrangler?

Max (@rozenmd)•7/27/23, 1:12 PM

just JSON atm

Max (@rozenmd)•7/27/23, 1:16 PM

if you know

jq

jq

you can convert JSON input to CSV output in your terminal, though

NNoel is it possible to get the query output as csv in wrangler?

Matt Silverlock•7/27/23, 2:52 PM

https://csvkit.readthedocs.io/en/latest/ is nice

Noel•7/27/23, 2:55 PM

thanks, looks like a good tool that i can use in the future

Noel•7/27/23, 2:56 PM

however this time i just ended up using a js snippet from so to convert the json in the browser console

the fix for this should land in 3-4 hours

CiabbataConda•7/27/23, 5:47 PM

could someone clarify me some things about D1? Is it based on sqlite, and, if yes, where can I find some list with supported features? Does it have support for foreign keys? can it be used with something like drizzle orm? thank you.

benjamin•7/27/23, 6:10 PM

Check out the T4 stack: https://app.t4stack.com/ I am working with it now and using Drizzle with it. I struggle with what is available vs. not too, but FKs are supported. There isn't yet support for transactions.

T4 App

Tamagui, Solito, Expo & Next.js

CiabbataConda•7/27/23, 6:13 PM

thank you for the recommendation and the input. I kinda wish the D1 documentation was more explicit. I've found in the meantime on another page that D1 is based on SQLite, but I believe this is something that should be mentioned in the D1 docs. Anyway, I assume this is because D1 is still in alpha.

CiabbataConda•7/27/23, 6:13 PM

Having FKs at least is good, means we won't end up with something like planetscale again
