Thx! I can confirm for our test tenant, but not the prod one. Still says insufficient invocations

Hey, where do I find D1 repository? Couldn't find it on GitHub.

James•11/23/24, 4:17 PM

For what specifically? You'll find some of D1 source in the workerdworkerd repo like https://github.com/cloudflare/workerd/blob/main/src/workerd/util/sqlite.c%2B%2B, but if you're new to D1, the Getting Started guide is going to the best place to start: https://developers.cloudflare.com/d1/get-started/

Hello everyone,

Quick question. Is D1 a suitable backend database for a financial wallet web application? i.e. ensuring consistency across users funds balances / withdrawing funds and depositing funds reflect consistently across all users of the wallet app. Is D1 sufficient for this use case? or will i need a Postgres db for example?

Thanks,

Larry•11/23/24, 8:53 PM

From a consistency perspective, D1 is on par with Postgres. Reliability and recoverability are more a function of how each is hosted and Cloudflare is well above average on this front. The biggest difference is scaling both in size and throughput. D1 maxes out at 10GB. Postgres DBs can be TBs. Similarly, D1 also has significant throughput scaling limitations compared to Postgres and I suspect that will continue even after D1 is upgraded to support read replicas.

João Castro•11/23/24, 9:30 PM

I remember reading a message about "unlimited read throughput" once read replicas arrive. But writes would still have the same throughput limitations as it has today.

This is the Cloudflare D1 channel, unrelated to MySQL. I'd recommend positing in #off-topic, but at the same time, there's not much we can do to help with a single screenshot of a MySQL process using a lot of resources.

hi. i've been trying to make d1 work in rust with bigint (i64) data types, and i keep getting this error: Error: Error: D1_TYPE_ERROR: Type 'bigint' not supported for value '300' - Cause: Error: D1_TYPE_ERROR: Type 'bigint' not supported for value '300'. what am i missing?

lambrospetrou•11/25/24, 9:51 AM

D1 is based on SQLite, so these are the types you can use: https://www.sqlite.org/datatype3.html
Not sure how Rust is involved in your code, but bigintbigint is not a valid SQLite type and gets converted to one of the native ones, in this case INTEGERINTEGER.

How are you using Rust, are you using the D1 Worker binding with Rust WASM, or something else?
That error is coming from the D1 Worker binding, so it expects JS types.

rumata•11/25/24, 12:30 PM

yes, i am using d1 worker with rust and i have a i64 variable, i am trying to bind to an Integer column when i get this error. Here is the code and schema:
Drop Table Test;
CREATE TABLE IF NOT EXISTS Test (
Id TEXT PRIMARY KEY NOT NULL,
Value INTEGER NOT NULL
);

rumata•11/25/24, 12:30 PM

let d1 = ctx.env.d1("DB")?;
let statement = d1.prepare("INSERT INTO Test (Id, Value) VALUES (?1, ?2)");
let v: i64 = 300;
let query = statement.bind(&["abc".into(),
v.into()])?;
let result = query.run().await?;
console_log!("result: {:?}", result.success());

rumata•11/25/24, 12:51 PM

i think i figured this out - i have to convert everything to string on rust side - and then despite things being strings, d1 interprets them correctly as integer of varying size.

lambrospetrou•11/25/24, 1:13 PM

Are you sure they are written as integers though? SQLite non-strict tables accept anything you give them regardless of the column type. I would suggest converting the i64 into a normal integer before passed to the statement bind call. Maybe this works, and you will keep them as integers.

Christian•11/26/24, 8:58 PM

Super weird issue but could it be that the Cloudflare D1 export via npx wrangler d1 export dharmaradio --remote --output=dump.sqlnpx wrangler d1 export dharmaradio --remote --output=dump.sql creates a dump which can't be imported again via npx wrangler d1 execute dharmaradio --remote --file=dump.sqlnpx wrangler d1 execute dharmaradio --remote --file=dump.sql.

The first issue is that datetime fields aren't put under quotes. After fixing that via multi-cursor editing I'm getting the following error {"D1_RESET_DO":true}{"D1_RESET_DO":true} .

I know D1 is still new but I would expect that I could import the dump I exported via it.

Original message was deleted

Christian•11/26/24, 9:12 PM

40mb but that doesn't explain why the export can't be imported

Original message was deleted

Christian•11/26/24, 9:23 PM

No, it first fails on parsing the sql because of the missing quotes around the dates. Once i fixed that it succeeds parsing the sql and then breaks with the d1_reset_do error.

I wrote a script to chunk the inserts in the dump so hopefully that works out but the export 100% has some issue

Isaac McFadyen•11/27/24, 12:42 AM

Correct, location hints won't be enough if it's for compliance. And I don't believe D1 supports Jurisdiction Hints like R2 (and even if it did, there's no Canada jurisdiction at the moment).

juanferreras•11/27/24, 7:24 PM

I was using nanoid on a small pet project and wanted to change the id lengths to start pretty small (probably 4 characters), and start increasing as we get more rows populated (to avoid collissions). Mainly to make some of the shareable URLs nicer for first users too

generally speaking, I wouldn't be concerned on doing a COUNT(id)COUNT(id) every X minutes and storing it somewhere like KV (from a database workload nor a performance standpoint). But I've just realized that'd be an EXTREMELY bad idea with SQLLite and D1 row-based pricing right?

juanferreras•11/27/24, 7:54 PM

aah that's a great solution! I think I can just setup triggers to keep those +1 automatic

lambrospetrou•11/28/24, 11:43 AM

You can find some query metrics for your usage as described in https://developers.cloudflare.com/d1/observability/metrics-analytics/
I guess the most relevant to what you asked is seeing the top queries and checking the tables accessed.

Not sure there's an immediate fix but we're surfacing these errors to the team so hopefully there's some communication at some point.

Don't worry, I'm using D1 just for a small hobby project so it's nothing critical

Shannor•11/29/24, 3:38 PM

Hey @DaniFoldi and @Isaac McFadyen the Database ID is 7356accc-d066-45c4-a577-9b9009c822eb. We use the DB pretty often at my company so it's definitely a weird error though sporadic. We're not able to reproduce it on purpse and it also seems like we get the error but the DB action still happens.

James•11/29/24, 3:47 PM

These kind of sporadic errors are unfortunately par for the course with D1. Here's some stats from an active DB for example: https://canary.discord.com/channels/595317990191398933/992060581832032316/1300948096964100097
The best you can do is retry queries until they work, sadly, but I wish I had better news for you.
