If your database has grown, then it's likely you're just running into the limitations of the original alpha

SSmallShen It looks great to make d1 a “schema-less” database, but performance is important

M

Matt Silverlock•5/19/23, 4:14 PM

It's going to really depend on what you're querying and what the shape of the objects you're using is. You also need to take into account the benefits of doing this in your database vs. in your application.

Can you share more information please? Specifically: your database ID, the query itself (with any PII redacted), and whether this is repeatable?

@elithrar just read the blog on D1 updates, great job guys, its looking promising. I have been waiting to hear about how we can create database per customer, however, nothing was mentioned about that in the blog. are you guys still considering that in near future or that will be available after GA?

I'm confused about the db size limits. The blog says in the pricing that 1GB is available to free users and 5GB included and $0.75/GB beyond that.

But then it says "Developerson the Workers Paid plan will get access to 1GB dbs in the very near future".

Does this mean that the limit is currently still 100mb, will soon be 1Gb and later will change to what the pricing shows?

maybe a better approach would be dbs per regional area

B

Bulbasaur•5/19/23, 6:17 PM

when a user creates their account, pick a db based on their geography to route to, and always use that db for that user

B

Bulbasaur•5/19/23, 6:18 PM

depending on how far you want to take that, you could do an NA region, EU region and Asia region for example, or more

Currently in alpha it is free to use and limited to 100mb. In the future those payment plans will come into play and the limits for dbs will be higher

It's interesting that it let me insert that row initially from within the worker, but not via wrangler or the console

Right now, deletes are treated as writes. Subject to change. Unless you're deleting a LOT of data, all the time, I'd be very surprised if your write+delete costs on D1 exceeded DO.
No limit on tables, but any table is non-zero bytes (to store the schema and allocate storage for an empty table). If an empty table is ~4KB or so you could have thousands of empty tables with no data, if you really desired to do so
