Ah interesting I saw the dump function. I was curious as I was wondering about a local python connection to query the db. I guess you would need a worker that evals the query. I'm testing d1 for my ai news aggregator:

You probably need a worker yeah, I know for a fact you can connect directly to turso currently with libsql

Jason Hostetter•9/30/23, 3:25 PM

Is it correct that there is no way to programmatically create or connect to different databases for users without an enterprise account?

Cyb3r-Jak3•9/30/23, 3:30 PM

I'm pretty sure even with enterprise you can't

Jason Hostetter•9/30/23, 3:32 PM

There was mention of creating one db per client in the beta announcement, but only for enterprise

Cyb3r-Jak3•9/30/23, 3:32 PM

Oh workers for platforms

Jason Hostetter•9/30/23, 3:32 PM

Although the description wasn’t super clear to me

Jason Hostetter•9/30/23, 3:32 PM

Yeah

Cyb3r-Jak3•9/30/23, 3:33 PM

Yeah, sorry haven't used WfP but that will allow you to

Jason Hostetter•9/30/23, 3:34 PM

Is workers for platforms enterprise only?

Cyb3r-Jak3•9/30/23, 3:35 PM

It is

Jason Hostetter•9/30/23, 3:35 PM

Bahhh

Jason Hostetter•9/30/23, 3:38 PM

Ok well, maybe I’ll have to try to hack something together with turso or something

Matt Silverlock•9/30/23, 4:01 PM

You can programmatically create databases - the D1 API isn’t limited to enterprise accounts at all. There is a limit on the # of DBs you create (at the moment) on regular accounts but we will increase this very soon

Jason Hostetter•9/30/23, 4:14 PM

Oh nice! Can I dynamically bind a database depending on some parameter or key passed in the request to the worker?

Matt Silverlock•9/30/23, 4:17 PM

No, that is something we don’t yet support. Working on it. If you can bind any resource in your account it would break the security model (how do you bind only the right things?) - so the work is focused on APIs to help group/tag resources vs “any”

Jason Hostetter•9/30/23, 4:37 PM

Great to hear, looking forward to it. Was worried that functionality would be locked behind enterprise, which would effectively kill my project (at least with D1)

Samantas5855•9/30/23, 10:00 PM

Can I add data to a d1 database from workers and a python script?

Samantas5855•9/30/23, 10:04 PM

also does delete count as a write or is it free?

SSamantas5855 Can I add data to a d1 database from workers and a python script?

Cyb3r-Jak3•9/30/23, 10:19 PM

You'd would have the use the API to add the content from a python script

Cyb3r-Jak3•9/30/23, 10:22 PM

And I'd imagine that deleting rows counts as a write but not about if you delete a D1 database entirely

With the release of hyperdrive, does it mean that today I could have a "read replica" of my data at all Cloudflare point of presence at my country, while with D1 I'll have to wait for the release of the read replicas? (being my country is Brazil, i don't even see a hint of D1 for south america)

Matt Silverlock•10/1/23, 5:43 PM

Hyperdrive doesn’t create replicas: it caches reads. Big difference.

I tried to imply that with the quotes, sorry for the miscommunication, and thanks for your answer. I’m looking for a pure performance standpoint. Looking to rewrite some parts of a product that I have for the maximum read performance. Right now all located on AWS SA and cloudflare on front caching the html static. Users all over Brazil, would love to have the data distributed for when the cache bursts. But I was actually reading hyperdrive doc further and the cache looks short for my use case as I don’t have that much reads because all is cached statically.

Matt Silverlock•10/1/23, 6:01 PM

Got it. Hyperdrive is still going to be a very effective intermediate cache - on top of the connection pooling & perf. Without it, cache misses will likely hurt a lot in terms of latency.

Thanks. That’s great to know. Rewriting the stack from .net 4 to workers after the TCP connection announcement. Most of it is ready, was going with a hosted AWS Postgres for development but looking for the feasibility at the hyperdrive/D1 after this week’s announcement. Will hyperdrive work with D1 or will D1 have that builtin with replicas at all the pop’s?

Separate things. Hyperdrive for databases not on Cloudflare. D1 as D1. Search this channel for my posts on “read replication” for D1

Laurent Pellegrino•10/2/23, 12:54 PM

Thanks for your message.

Yep, it's somewhat like a read-only replica. But the challenge is that about 90% of the data is refreshed daily, so diff computing or event-based reactions won't be of much help. I think @rozenmd's generic response might be due to Cloudflare not wanting backups to be abused. If I'm not mistaken, backup imports don't count as writes. So, in theory, someone could set up a local database, fill it up, back it up, and then import to Cloudflare D1 at no cost. Those backups weren't just for disaster recovery; they fit my scenario perfectly. But with only Timetravel remaining, the $1/M write cost is steep for those of us needing to import large databases daily or even weekly only.

Max (@rozenmd)•10/2/23, 12:59 PM

backup imports don't count as writes

D1's beta backend doesn't have backup imports - you can write to the DB, and you're billed as a write.

Metrics do not appear for D1's older alpha dbs because the metrics feature was built only for the beta backend.

Matt Silverlock•10/2/23, 1:40 PM

FYI: you will be able to create up to 50,000 D1 databases per account as of this week (and if you genuinely get close, we can increase further: this is a soft limit).
