hmmm - thats very interesting and I had not considered that - thank you so much for that insight

Old Man Maker•10/19/23, 8:31 AM

You just use an API to duplicate it?

Old Man Maker•10/19/23, 8:32 AM

I was just noticing there is a limit of 500 workers per account

MichałOP•10/19/23, 8:32 AM

It's more complex than that in our case but more or less yeah

Thanks for that info - really appreciate it

MichałOP•10/19/23, 8:37 AM

I think that can be increased on individual basis but I can't speak for Cloudflare, not affiliated or anything

GuillaumeLakano•10/19/23, 1:58 PM

Hi ! The LIMIT in a UPDATE/DELETE request doesn't seems to be supported, it's depend of the configuration of SQLite ( https://www.sqlite.org/compile.html#enable_update_delete_limit ), is it possible to enable it please?

OOld Man Maker Thanks for the response, I assume this is under a bindings API?

This is an interim solution, for what it's worth. As we've called out before, we're working on a way to bind to a group of resources that can grow/shrink over time. This won't be "next month" though, but before D1 GA.

Old Man Maker•10/19/23, 2:58 PM

Thanks for that information. I'll do some tests around this. As @Michał z typeofweb.com mentioned his approach, my very real fear is discovering an issue in the root worker, and then needing to update N workers who were copied.

Samantas5855•10/19/23, 3:01 PM

While implementing D1 on Pages Functions I copied the example from here to get the first element of the table and it seems to take about 1.5s

Samantas5855•10/19/23, 3:02 PM

Why is it so slow? Is it possible to speed it up?

schwartzmj•10/19/23, 3:04 PM

I see Backups are legacy and "Time Travel" is the new thing. Am I not able to download a local backup of my database now? You could with the legacy method but not seeing a way with Time Travel

zegevlier•10/19/23, 3:05 PM

It is currently not possible to download D1 databases that are using the new backend (=that have time travel). There is a community project that lets you do that though

Matt Silverlock•10/19/23, 3:30 PM

Right now you can bind up to ~5000 databases per Worker (conservatively), so I suspect this isn't an immediate problem just yet / before we have a better solution.

Old Man Maker•10/19/23, 3:34 PM

Thanks Matt. Given that the binding is added, can I access it with a key?
E.g const result = env[binding_name].prepare(,,,,)?

Old Man Maker•10/19/23, 3:35 PM

The binding name will be a parameter passed into the worker

Old Man Maker•10/19/23, 4:00 PM

I'm actually thinking I might be going about this all wrong for this particular use case - in D1 we've got a hammer, so everything looks like a nail.
In this instance, I think I may be better off using KV as the storage mechanism
This has been a really interesting exercise in considerations and thanks to everyone who has put thoughts, ideas and solutions into it. Much appreciated

Matt Silverlock•10/19/23, 4:07 PM

We're still designing the interface, but effectively being able to address databases/resources by name/ID at runtime.

Cyb3r-Jak3•10/19/23, 10:11 PM

It should be all sqlite data types which are NULL, INTEGER, READ, TEXT and BLOB

SnowyYANG•10/19/23, 10:12 PM

so d1 is sqlite?

Yes

SnowyYANG•10/19/23, 10:17 PM

I have a large complex MySQL application (like erp), is it smart to migrate to D1?

Cyb3r-Jak3•10/19/23, 10:27 PM

How are you connecting to the MySQL DB? There isn't a connection string that you can use to connect to a D1 DB externally, done through a worker or HTTP

SnowyYANG•10/19/23, 11:07 PM

I originally plan to use PHP+MySQL. If I migrate MySQL to D1 then I have to migrate PHP to Worker.

We deploy a copy of the worker along with a database for each client 🙂 Not sure if that helps your
