I think you're after batch? https://developers.cloudflare.com/d1/worker-api/d1-database/#batch
Cloudflare Docs
To interact with your D1 database from your Worker, you need to access it through the environment bindings provided to the Worker (env).
Kyeah this is what I'm looking for. Thanks @Dean ! 
DI don't believe there is anything in writing on the D1 roadmap. Officially we know they're working on database replication but that's about it 
OQ. The overview doc says:
How does this work? Can I provision a new one programatically (perhaps via CloudFlar API) or am I to create new D1 manually?
Or these multiple databases are provisioned automatically for me, e.g. my users in Japan would have one while my users in Brazil will have a different one?
In either of these scenarios the databases would have different data right?
OR
These databases are automatically replicated through CloudFlare's network and each group would have one D1 (Japan, and Brazil) but with the same data? If that's the case that means the max storage globally is 10gb?
I couldn't find this information in the docs.
D1 is designed for horizontal scale out across multiple, smaller (10 GB) databases, such as per-user, per-tenant or per-entity databases. D1 allows you to build applications with thousands of databases at no extra cost for isolating with multiple databases. D1 pricing is based only on query and storage costs.

DYou can create multiple databases via the API and set a location hint: https://developers.cloudflare.com/d1/configuration/data-location/#:~:text=Location%20hint%20is%20an%20optional,are%20creating%20the%20database%20from They are not automatically provisioned in different regions. They would have different data. D1 databases do not have replication yet, however that is something that is expected to come soon.
OExcellent, thank you for clarifying.
My use case is precisely that. Think of a reddit clone, every subreddit can have their own D1 located where it was created.

Dsomething to keep in mind, while cloudflare allows 50,000 databases, they only allow a max of around 5000 databases to be binded to a worker or CF pages.
OI see. Well I'm way too far away from that volume yet, so that will be a good problem to have
OThank you @Dean
DYou’re welcome
ぷOn Cloudflare d1, when I use the execute command, the table creation works when remote, but when local, I get an EOF error.
- wrangler version: 3.109.1 (install by bun)
- schema.sql
- wrangler.jsonc
- run command: wrangler d1 execute test-d1 --local --file=schema.sql (EOF ERROR)
- run command2: wrangler d1 execute test-d1 --remote --file=schema.sql (SUCCESS)
- what I tried: wrangler reinstall, bun cache ckear,
D"compatibility_flags": ["nodejs_compat"]
"pages_build_output_dir": .vercel/output/static",
missing a comma at compability_flag and the outbound directory missing a "
"pages_build_output_dir": .vercel/output/static",

Dother than that, looks okay
ぷI fixed it, but it still doesn't work.
DDoes your schema file end with comments?
ぷNo, it doesn't
DI faced this weird error where having comments at the end threw errors
DLooks like not the case here
ZHey, been testing out d1 doing bulk imports of data, the upload appears to now be failing though with a gateway timeout. Any idea what's going on there?
ZThis was while it was trying to check if it should upload the .sql file or not
JHow large is your sql file? Can you reproduce it consistently? Can you share a reproduction if so?
ZIt was working consistently earlier, I have uploaded the same sized files repeatedly and then wiped the database. The files are around 30MB each
ZI'm uploading 50 one after another to chunk the ingestion
ZIts around 6 million total rows
ZThe weird part was it wasn't even failing to upload, it was failing on the check to see if it needed to upload. It never actually got that far
ZJust tested again now and still experiencing this problem, I effectively can't import any .sql files right now
ZThe entire D1 (non-worker) API seems to be significantly slower for me compared to earlier today
ZIt appears that wiping the table and starting again resolves the problem, so it may be something that gets worse as the table gets bigger?
Jidk if i am right here; but the german translation for table in the webui is absolutely wrong:
Jis there any way for cloudflare to change it to the correct translation? it would be "Tabellen"
�Ki übersetzungen sind doch was tolles 
ZZIs this in preparation for read replicas? 
Ai hope so

Aat this point I wonder if theyre waiting until developer week (which is april iirc?) to launch it
Johja, richtig klasse :D
AIs D1 down? Getting lots of
Error: D1_ERROR: internal errorALooks to be working now, but there was about 4 mins of downtime (no changes made on our end)
ACan i ask a doubt like can we use the D1 on the nextjs hosted on verel and i am unable to use it on local development i have separrte backend in hono cf workers for admin pannel but for seo i am trying to access the data within the nextjs but still i can't can anybody help
UYou cant use D1 on vercel in that way. Vercel doesnt have cloudflare bindings. If you wanted to query D1 from Vercel you would need to either use the Rest API or create a worker to proxy requests to the D1 binding.
Aso are you mentioning that i should use my hono backend in cf workers to power the users front end also like fetch data in server are try to cache it to increase perfomance ? and also i don't get this point "create a worker to proxy requests to the D1 binding." like can you explain or do you have any article on it
Ai also tried to host nextjs in pages but the styles are breaking in pages preview
UNot referencing cache or performance at all. Just pointing out that you cannot access a cloudflare binding from vercel because vercel is not cloudflare.
The only way to query data from D1 from the vercel servers would be to call a cloudflare worker or the cloudflare api.

AI am confused like on production we can use the db url in the drizzle and it will handle the db interactions so i thought that we can use d1 in the vercel but on development stage we need local db as per the d1 docs
LD1 doesn't have a connection URL as traditional databases. Either you query D1 through a Worker using the D1 binding (https://developers.cloudflare.com/d1/worker-api/) which is the fastest and most performant, or you should use the D1 REST API (https://developers.cloudflare.com/api/resources/d1/subresources/database/methods/query/).
I do not recommend the REST API if you will do several database queries (round trips), since it's not meant to be used yet in your hot paths. It's slow at the moment, more rate limited than the Workers binding, and you won't have a nice experience. We are improving this in the following months but it's a long ongoing process.

AThankyou for the detailed info. so like i am planing to go with the acessing data from my workers using hono

Mwait, do they have multiple developer weeks a year? I recall one being just recently
Wwe have multiple innovation weeks (Birthday week, developer week, security week, privacy week, etc.)
Wbut only 1 developer week a year
