At least D1 doesn't error if you don't specify a `preview_` :^)
At least D1 doesn't error if you don't specify a
preview_
Hyeah with r2 i had to specify a preview for any env that is not at the top level configuration of wrangler.toml
Hwhich i just set to be the same as the top level bucket anyway 
KYeahhh, it's not the best
Mah I see
Mwow the beta backend is incredibly fast compared to the alpha backend
Jnew D1 backend be zoomin' yeah, it's such a wild improvement
Myeah I did a double take because I thought they just changed the units in wrangler from
mssdoes
stmt.raw()
Wsame question. I am very much looking forward to the day D1 officially launches.
Mturns out native code is faster than WASM 
Mupdate your wrangler.toml to be:
Min Pages you'd have to configure the binding via the Cloudflare dashboard
THi guys, has the new D1 engine had backup feature?
Tand is it stable enough to not losing data or failed unexpectedly?
MYou can now roll your database back in time up to 30 days - we're still in alpha though.
Tthanks
Tthe old D1 engine works pretty well for me! Should I expect the same consistency with D1 new engine?
Tand is there anyway I can restore database from a local backup?
Myou can expect a performance improvement, here's what we noticed:
Myou'll need to dump the local backup to sql first: https://developers.cloudflare.com/d1/learning/importing-data/#converting-sqlite-database-files
TThanks.
Mthat was just execution
Mwe have yet to find a solution to beating the speed of light
Myeah that ones kinda pesky
Nis it possible to get the query output as csv in wrangler?
Mjust JSON atm
Mif you know
jq you can convert JSON input to CSV output in your terminal, though
Nthanks, looks like a good tool that i can use in the future
Nhowever this time i just ended up using a js snippet from so to convert the json in the browser console 
Mthe fix for this should land in 3-4 hours
Ccould 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.
BCheck 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.
Tamagui, Solito, Expo & Next.js
Cthank 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.
CHaving FKs at least is good, means we won't end up with something like planetscale again
HDrizzle specifically supports d1, you can see how to set it up in their documentation (https://orm.drizzle.team/docs/installation-and-db-connection/sqlite/d1). Foreign keys are also supported (as sqlite have support for foreign keys). I agree with you planetscales lack of support for FKs was such a pain
NHey everyone, when a D1 is created and the replicas distributed through the network. I wanna know if that D1 is always up and running or if it only runs when a request has been made to it?
Cif I were to answer by intuition, given that D1 is based on SQLite it doesn't actually "run" anywhere – it's just a file on each node of the network. "Replication" of D1 is basically copying the database file across nodes, just as the static assets of a website would be. For the database to "run", I assume that a Worker reads the database file on request, if necessary, and works with that.
In essence, you could say that D1 "runs" only when a request is made. But it really never runs, as it is not a server. Pricing also reflects that (https://developers.cloudflare.com/d1/platform/pricing/): notice that the metrics by which usage is priced are reads, writes, and storage (which are characteristic to file usage), but not something like CPU time (which is characteristic to a server).

CIf somebody spots a mistake please correct me.
NPerfect that makes sense and thank you for all the other tid bits of information.
HD1 is not currently replicated, and iirc they hibernate after around 30 seconds of inactivity
NSo, a typical PostgreSQL requires a server to be up and running at all times to serve records. But since D1 is built on SQLite - from what I understand, SQLite is serverless and doesn't require a server - it's just a file like CiabbataConda said.
just learning all this

NI intended to use PostgreSQL for the project I started building and now I am wondering if I can use D1 instead
HSort of. Standard SQLite is just a file plus some code to read it. But how D1 works is that it is some code that Cloudflare runs for you, on top of that file. So yes, that service may need to be cold-booted occasionally if it hasn’t been called in a while, but as Skye pointed out, bootups occur in the order of a few milliseconds, so it shouldn’t be anything you need to factor into your plans
Cwhere do you get this info from? is there some documentation on the internals which I am incapable of finding?
