This is method to get db instance

  const DB = getRequestContext().env.AI_FORM_GENERATOR_DB;

  return drizzle(DB, { schema });

export const getDBInstance = () => {

};

export const getDBInstance = () => {
  console.log("getRequestContext", getRequestContext);

I'm getting timeout errors when trying to modify the schema of a table. " Error: D1_ERROR: D1 exceeded its CPU time limit and was reset."

The users table has 18k rows and 6 tables have foreign key references on it so that's probably why its taking a lot of time. But because of this I'm kind of stuck with not being able to modify my users table.

Having an issue with this D1 insert. The DB binding is fine (another function reads from the DB OK), but this insert just will not execute. It gets to the "Preparing to insert.." line OK and then black hole - not even an exception error. Simplifying by stubbing in values to avoid type mismatch issues didn't help either.

Natalie•5/8/24, 9:51 AM

Hi there. I'm building an realtime 3d texturing application and am planning on utilising cloudflare D1 as the backing store. My problem is that given the limit of 50k databases each with a max size of 10GB, I'm unsure what would be the best architecture to adopt. My initial instinct would be to create a DB per organization, but that means I could only have up to 50k orgs. Given a pareto assumption of organization, probably most of these databases would be under-utilized. So an alternative would be to shard the data somehow, but that could quickly becomes awkward if remote joins would are needed. So I'm a bit confused about how D1 fits into the SaaS use case

N

Natalie•5/8/24, 9:54 AM

The pricing docs for D1 mention:

Every query returns a meta object that contains a total count of the rows read (rows_read) and rows written (rows_written) by that query. For example, a query that performs a full table scan (for instance, SELECT * FROM users) from a table with 5000 rows would return a rows_read value of 5000:

"meta": {
  "duration": 0.20472300052642825,
  "size_after": 45137920,
  "rows_read": 5000,
  "rows_written": 0
}

These are also included in the D1 Cloudflare dashboard and the analytics API, allowing you to attribute read and write volumes to specific databases, time periods, or both.

But where can I see these rows_read statitiscs in the dashboard?

I'm trying to find out how count queries are calculated...

Imagine I have a

select count(1) from customer where country_id = 'uk'

select count(1) from customer where country_id = 'uk'

what is the cost for such a query?
Is it equals to the number of rows in the customer table?

R

roftt•5/8/24, 3:24 PM

Try this in your worker:

const stmt = db.prepare('select count(1) from customer where country_id = "uk"').all();
console.log(stmt.meta.rows_read)

const stmt = db.prepare('select count(1) from customer where country_id = "uk"').all();
console.log(stmt.meta.rows_read)

const stmt = db.prepare('select count(1) from customer where country_id = "uk"').all();
console.log(stmt.meta.rows_read)

const stmt = db.prepare('select count(1) from customer where country_id = "uk"').all();
console.log(stmt.meta.rows_read)

Overall statistics for rows_read of the entire database is in Dashboard -> Your DB -> Metrics
And don't forget to use indexes, it reduces rows_read drastically

If you open DevTools, the

Marcel Overdijk•5/8/24, 5:38 PM

That was indeed useful.
So when a

customer

customer

table contains 900 records both queries

select * from customer

select * from customer

and

select count(1) from customer

select count(1) from customer

will have

"rows_read": 900,

"rows_read": 900,

Marcel Overdijk•5/8/24, 5:39 PM
