Hi all, in Neon they have the concept of bottomless storage, where cold data can be written to a cheaper location, for example S3. Is this something that D1 also wants to offer in the long run?

Matt Silverlock•8/4/23, 12:43 PM

D1 doesn’t charge for CPU hours or data transfer, and “cold” storage in the way Neon refers to it doesn’t make much sense here. We don’t think storage is ever the dominant cost for a transactional database.

Does D1 support transaction?

I’m trying build a web app with next-on-pages, D1 and drizzle-orm.

Drizzle transaction API seems to be working fine for local development. However, it fails on production and preview deployments with the following error “Error: D1_Error: Error: not authorized”

This doesn’t looks like a binding issue as all other non-transaction calls to D1 works without any errors.

itsmatteomanf•8/5/23, 9:43 AM

The team mentioned possible plans to expose a transaction API, but not soon. Haven’t tried, but can’t you just add multiple commands in the same statement?

Vishnu Sankar•8/5/23, 9:57 AM

It’s not practical to write all commands in a single statement. Here’s a simple snippet of creating and org and adding a admin to it.

/**

Create org
@param userId
@returns*/export const createOrg = async (userId: string,input: CreateOrgFormSchemaType,) => {return db.transaction(async (txn) => { // Create org const org = await txn .insert(orgs) .values({ ...input, id: getNanoId() }) .returning() .get() // Create admin member await txn .insert(members) .values({ id: getNanoId(), userId, orgId: org.id, role: 'admin' }) .returning() .get() return org})}

itsmatteomanf•8/5/23, 9:59 AM

Not saying it's easy, but it can be done and I am not seeing anything there that doesn't allow it.

itsmatteomanf•8/5/23, 9:59 AM

It's a workaround, after all.

Vishnu Sankar•8/5/23, 10:01 AM

The only option is to use OUPUT INTO, however the above two statements are not the full logic, it involves even more inserts to multiple other tables.

Writing them all into one statement will make it hard to debug or maintain.

itsmatteomanf•8/5/23, 10:02 AM

Oh yeah, definitely not easy. From what the team has been saying they have some priorities before this. It's an alpha, after all.

Vishnu Sankar•8/5/23, 10:09 AM

Hmm, hope the team address this issue. It’s a must for any sort of complex logic

Bram•8/5/23, 11:19 AM

you can use batch statements in your case, considering you generate the ID client side

Original message was deleted

Vishnu Sankar•8/5/23, 11:20 AM

@nora8008 Looks like batching only execute array of statements, it can be useful for bulk writes.

From the docs, it doesn’t looks like it returns any values from previous statements in the batch array.

In my case, I’m trying to create an org and adding a member to it, to create a member row, I need to know the org id, which only returns from previous steps

Bram•8/5/23, 11:20 AM

Vishnu Sankar•8/5/23, 11:22 AM

@alphadog_ Yes, for this sample code snippet, I’m generating the id. However I mentioned in my early message that it’s a small part of the logic.

The full org creation logic involves creation of other tables which are using incremental ids. Which are non-deterministic.

Original message was deleted

Vishnu Sankar•8/5/23, 11:26 AM

@nora8008 I’m sorry I didn’t get you. What benefit it would make by adding a status column?

Interactive transactions are really important for complex logic management.

Bram•8/5/23, 11:37 AM

I think nora means that you could coordinate the state of a transaction yourself by utilising an additional column. Let's say you have two batch statements and the 2nd goes wrong, you have a way to identify till how far your unit of work has executed. But I fully agree that it would be a great DX improvement if we could have a transaction API, but it is (as far as I know) not actively worked on. They are adding other core functionality first. Keep in mind it is in alpha and clearly states that it is not intended for production usage.

Vishnu Sankar•8/5/23, 11:42 AM

@alphadog_ Hmm, that’s bit confusing. Aren’t they supposed to rollback all the changes if any of the statement fails? In that case, what purpose the additional column serves?

I think for now, I’ll have to sacrifice the non-deterministic id part. That seems to be only option till the team implements js transaction api

VVishnu Sankar @alphadog_ Hmm, that’s bit confusing. Aren’t they supposed to rollback all the c...

Bram•8/5/23, 11:49 AM

I am not too sure if this is what Nora meant, but in a microservice architecture they have something called the "Saga pattern" (https://microservices.io/patterns/data/saga.html) where you coordinate a distrubuted transaction yourself. It boils down to having some kind of statemachine where you are responsible for rolling back changes along the way. You could apply a similar (simplified) approach in your app, but imo it's not worth the complexity, especially considering you have everything in one database. I would indeed avoid using auto incementing ids or use another database that integrates well with cloudflare workers (see https://developers.cloudflare.com/workers/databases/connecting-to-databases/)

microservices.io

Microservices Pattern: Sagas

Implement transactions using a saga, which is sequence of local transactions
