Hey. I have a question about row metrics. The metrics showed a lot more writes than I expected, so I started looking more closely at the response meta. This one query tries to do an insert, and if there's a conflict on the primary key, it updates the row instead. It shows one read and eight (?!) writes. Am I interpreting the meta correctly? And is this the expected result? Thank you!

All queries inside each

batch

batch

call are executed inside a single transaction: https://developers.cloudflare.com/d1/build-with-d1/d1-client-api/#batch-statements

Batched statements are SQL transactions . If a statement in the sequence fails, then an error is returned for that specific statement, and it aborts or rolls back the entire sequence.

You could maybe make your second query to do a SELECT on the UsersTable based on the

googleUser.email

googleUser.email

and use that in your INSERT.

lambrospetrou•10/1/24, 1:59 PM

I am saying do both INSERTs in the same

batch()

batch()

, but your second INSERT should do a nested SELECT to figure out the user ID that was added in the first insert.

Also, actually in your case above, just move the

nanoid()

nanoid()

into a local variable before you create your statements, and use that in both queries. Isn't that nanoid what you want in the second insert or is it an autoincrement key?

I don't think this is right. The

.get().then((res) => res?.id!)

part needs the query to actually run I imagine. I am not familiar with this framework you are using for constructing your queries.

Out of curiosity, with Durable Objects having a KV API, and now an SQL API, what would you get out of a document API? I guess a library could provide this ontop of the SQLite API, but I am wondering if you have something else in mind that could be provided except the API itself.

mallets•10/3/24, 7:35 AM

Now I don't what's easier for CF to implement, but I wouldn't mind the 10GB/database limit if we can have 1 DB per user. These DBs could end up with 100KB max or a couple GB.
But that runs into the 50K limit. Will CF increase this limit easily upon request or should I just fragment tables over multiple DBs?
Feels like managing a "managed" DB service.

mallets•10/3/24, 8:23 AM

Good to know.
Unrelated, but I am confused by the pricing per read request. An old 2023 blog post mentions read units (4KB), while the current pricing is simply per row read.
Hope that means reading a "heavy" 512KB blob row still counts as a single read now?

mallets•10/3/24, 8:30 AM

Also a bit odd that it's "cheaper" to store small files on D1, if they need to be accessed a lot. R2 is 360x more costly per read but 50x cheaper GB/month.

If this is about query latency, there is a good chance the worker was invoked on the other side of the globe. Something about routing priorities based on account plan. A CF node exists in the same city as me but connections to any free plan resource is 8000kms away.

I also read that again recently and was surprised by the stored procedure reference. That was an earlier discussion of the possibilities but instead of getting implemented inside of D1, my best guess is that this is now implemented by using DOs with the sql.exec()sql.exec() interface.

hey folks, what's the typical workflow for teams working with D1? I was able to get pages+d1 working great with preview environments etc, but a few things are falling short... every time I create a PR, I'm using wrangler pages deploy --branch $BITBUCKET_BRANCHwrangler pages deploy --branch $BITBUCKET_BRANCH to deploy a preview environment and wrangler d1 migrations apply --remote --env previewwrangler d1 migrations apply --remote --env preview to apply the migrations to the preview db. that's awesome and pretty easy. however, all the preview envs share the same database, so how should I handle two PRs making db changes? or another very common use case: I start my PR with a single db change, but after PR reviews, I want to add/remove changes from the migration.
kinda the same issue as local development: if I checkout a branch to test it locally, then I can't really reset my local d1 instance to how it was before. I have to rm -rf ./.wrangler/state/v3/d1rm -rf ./.wrangler/state/v3/d1 and re-apply the migrations from

Ashley•10/5/24, 9:09 AM

I would personally spin up a whole new environment per branch like you’re doing but then as it’s a serverless platform, it’s pretty easy to have a script that creates new resources, do a bit of Bash to extract the bindings from the create commands, and then put in wrangler.toml and then do your deploy. You’d probably want some clean up to run on merge to delete the resources too (if you’re using GH Actions or something)
