if you add caching to your Worker so it doesn't have to wait for the request from singapore to come back each time, it'll be insanely fast, see: https://developers.cloudflare.com/workers/examples/cache-api/

If you enable Smart Placement in the dashboard for your Worker, the Worker will move itself to Sin, so only the first hop is slow, and the round-trips will be fast

I'm trying to understand this metric, on the selected chart I have "Rows Metrics" selected, as you can see there was some spikes very weird on selected dates, I don't think what I'm doing requires that many rows read, like the max I probably have is like 50K rows, is this an indication of a compromised db? How can I dig deeper?

looking at your tables list counts as a read on every row in every table, so it could be as simple as that (we plan to address this)

the query looks good, the top one is something I'm doing but it looks just too odd

Max (@rozenmd)•2/9/24, 12:53 PM

it counts towards your quota, but bare in mind you get 25 billion per month with the Workers $5 plan, so you could repeat that week 1470 times before you start getting billed for additional usage

Is there a direct method or do I have to go through a worker?

M

Max (@rozenmd)•2/9/24, 3:52 PM

going through a worker is the most performant way: https://github.com/elithrar/http-api-d1-example

M

Max (@rozenmd)•2/9/24, 3:53 PM

otherwise there's the API, but it's not running from Workers, and will be slow: https://developers.cloudflare.com/api/operations/cloudflare-d1-query-database

I need to improve that error, but D1's beta databases don't allow you to "create" or download your backups yet, you'd need to use a 3rd party tool like https://github.com/nora-soderlund/cloudflare-d1-backups, see also: https://developers.cloudflare.com/d1/reference/time-travel/

Billing data is available via

Sorry if this gets asked a lot, I just can’t get my head around it. Are you able to connect directly the a D1 db outside of wrangler or code or the dashboard. Eg in a normal desktop db application/client?

Yanni•2/10/24, 3:28 PM

Is there a way to insert many data during a worker run. I'm thinking about 2k-3k of rows. I only know how to insert one row per execution which is really inefficient. Is there a better way?

Y

Yanni•2/10/24, 3:33 PM

There is currently a limit of just 1000 queries which is like nothing

Y

Yanni•2/10/24, 3:33 PM

the job should detect increments which means that It hast to first query by id and the insert new datasets

Y

Yanni•2/10/24, 3:34 PM

and this ~2'000 - 3'000 times. I would also be fine by deleting everything first and then inserting it which would work if there is a option to insert multiple rows at the same time

something like this

INSERT INTO db VALUES (1), (2)

INSERT INTO db VALUES (1), (2)

INSERT INTO db VALUES (1), (2)

INSERT INTO db VALUES (1), (2)

Y

Yanni•2/10/24, 3:37 PM

this job should only run all 24h or maybe only every week the data doesn't really change over time but I'm to lazy to do it manually via cli or a local python script.

Denver James Duran•2/11/24, 5:10 PM

Hi! Can I ask for assistance.. so I am using D1 as my database I am required to store dates, so what I did was to first convert the date into numbers with this function

const MS_PER_DAY = 24 * 60 * 60 * 1000;
const EPOCH_1900 = new Date('1899-12-30T00:00:00.000Z').getTime();
export function dateToExcelNumberWithTime(date: Date): number {
    const gmtOffset = date.getTimezoneOffset();
    const adjustment = (0 - gmtOffset) * 60 * 1000;
    const finalDate = (date.getTime() - EPOCH_1900 + adjustment) / MS_PER_DAY;

    return finalDate;
}

const MS_PER_DAY = 24 * 60 * 60 * 1000;
const EPOCH_1900 = new Date('1899-12-30T00:00:00.000Z').getTime();
export function dateToExcelNumberWithTime(date: Date): number {
    const gmtOffset = date.getTimezoneOffset();
    const adjustment = (0 - gmtOffset) * 60 * 1000;
    const finalDate = (date.getTime() - EPOCH_1900 + adjustment) / MS_PER_DAY;

    return finalDate;
}

const MS_PER_DAY = 24 * 60 * 60 * 1000;
const EPOCH_1900 = new Date('1899-12-30T00:00:00.000Z').getTime();
export function dateToExcelNumberWithTime(date: Date): number {
    const gmtOffset = date.getTimezoneOffset();
    const adjustment = (0 - gmtOffset) * 60 * 1000;
    const finalDate = (date.getTime() - EPOCH_1900 + adjustment) / MS_PER_DAY;

    return finalDate;
}

const MS_PER_DAY = 24 * 60 * 60 * 1000;
const EPOCH_1900 = new Date('1899-12-30T00:00:00.000Z').getTime();
export function dateToExcelNumberWithTime(date: Date): number {
    const gmtOffset = date.getTimezoneOffset();
    const adjustment = (0 - gmtOffset) * 60 * 1000;
    const finalDate = (date.getTime() - EPOCH_1900 + adjustment) / MS_PER_DAY;

    return finalDate;
}

the thing is, no matter what I try, I really find it hard to synchronize time.. it just wont behave as what I am expecting.. my question is, can D1 support the actual DATE/ Timestamp to be saved on rows instead of me converting it to number then converting it back to date I think it complicates things (do you have any pointers on this or any tips?)

45332.058900462966

45332.058900462966 which I thought was easier to query. the numeric part is the number of days while the decimal is the time.. if I am querying a BETWEEN statement, the process will be straightforward..
