Hi I would like to know if there is a way to remove data back in time in the D1 time travel backup databases.

In these days of GDPR it is a very relevant feature that you are able to remove data from your backups.

How to get

object (duration, row_read, row_written) in D1 + Prisma query?

1984 Ford Laser•9/13/24, 7:54 AM

I have a bunch of data in a mongo install that I want to move to D1. For ease of development and saving my sanity, is there any downside to storing all data in D1 as JSON? and just querying the json as necessary? Would have index columns as independent columnds outside of the JSON column. Mainly wondering about performance issues that may arise

oof2win2OP•9/13/24, 9:36 AM

use jsonb. you can create indexes on expressions so you can essentially index say a userid field on a json (or something deeply nested as well)

oof2win2OP•9/13/24, 9:36 AM

jsonb because it is stored better and performs better, but even normal json has the ability to be indexed

You say 5-6GB per user, what is the data? Sounds like a good candidate for R2 with using D1 to store references to the files on R2

Your DB starts returning an error on inserts I believe.

Isaac McFadyen•9/13/24, 1:57 PM

The 10GB is not raisable. The question above was for the account-wide limit across multiple DBs.

nulled•9/13/24, 3:03 PM

Do you mean an UPDATE trigger that updates a timestamp on a table each time you sent an UPDATE to some table? If so I've been using exactly that for as long as I've been using D1

CREATE TRIGGER trigger_name AFTER UPDATE ON table BEGIN UPDATE another_table SET timestamp=UNIXEPOCH('NOW') WHERE column=some_val; END

CREATE TRIGGER trigger_name AFTER UPDATE ON table BEGIN UPDATE another_table SET timestamp=UNIXEPOCH('NOW') WHERE column=some_val; END

CarmeloCampos•9/13/24, 7:32 PM

if I have two different projects, and I need to use the same database (D1) how can I share the schemas?

Similar to the above, if I'm running to workers locally, how can I get them to share the same database?

conor•9/14/24, 6:09 PM

I tried that, state persists but it doesn't have my migrations applied and doesn't seem to want to apply them (no migrations to apply!). ~~Do I have to use the same flag for the migrations command I wonder?~~

Same flag not applicable to the migrations command and I'm not sure there's an equivalent.

I get:

✘ [ERROR] Implications failed:

   persist-to -> local

✘ [ERROR] Implications failed:

   persist-to -> local

But when I use

--local

--local

instead of persist-topersist-to for migrations I get :white_check_mark: No migrations to apply!:white_check_mark: No migrations to apply!

Ah ok! You need to supply both the --persist-to--persist-to flag and the

flag. I imagined --persist-to--persist-to would imply locallocal because I didn't think it was possible to direct persistence to a path remotely?

conor•9/14/24, 6:34 PM

What events can you trigger on in D1 and to what resolution?

Can I trigger on row creation that meets specific criteria? E.g. a row was added with this value for that column?

yeeet•9/14/24, 10:12 PM

hi is it possible to save a d1 prepared statement in a global variable or something when my worker is initializing, so I can reuse it across multiple invocations? currently, I've got the following:

export class SampleEndpoint extends OpenAPIRoute {
  
  async handle(c) {
    const stmt = await c.env.DB.prepare(...);
  }
}

export class SampleEndpoint extends OpenAPIRoute {
  
  async handle(c) {
    const stmt = await c.env.DB.prepare(...);
  }
}

so unless there's some sort of caching under the hood, I guess it'd have to parse the query every time my handler gets called, which I want to avoid. Mainly, I'm not sure how to access the c.env.DBc.env.DB object from outside the handlehandle function of an endpoint

edit: actually i'm gonna introduce a db abstraction layer which caches prepared stmts in global variables and if there's no prepared stmt cached then it creates a fresh one. from reading online, it seems like global variables' consistency guarantees would b fine for this sort of use-case

akashra•9/15/24, 8:15 AM

Right, so in this case, you should probably consider writing something that either enabled these to be batched from whatever is calling to the worker, or having them push to a queue which can periodically process data off that queue if you don't require synchronous responses.

sqlite should 100% be able to handle 300 writes per second

Ooof2win2 sqlite should 100% be able to handle 300 writes per second

akashra•9/15/24, 8:17 AM

It can, but I was more getting at why if you have a single process responsible for initiating all of these, why you're calling 300 separate queries when they don't need to be - or can be procesed without the overhead of locks in different sessions.

oof2win2OP•9/15/24, 8:18 AM

wym they don't need to be

oof2win2OP•9/15/24, 8:18 AM

its 300 separate http requests so 300 separate inserts make sense

akashra•9/15/24, 8:18 AM

you gotta remember how each worker is loading that data, obtaining the lock to write that data, then having to process that to write back and return.

akashra•9/15/24, 8:18 AM

yes - why are you doing 300 separate http requests - from the way this is a specific number, it sounds like they all come from the same client?

oof2win2OP•9/15/24, 8:19 AM

i just did 300 at once

oof2win2OP•9/15/24, 8:19 AM

they come from db triggers

oof2win2OP•9/15/24, 8:19 AM

it's possible i get only 1 and it's possible i get 2000

akashra•9/15/24, 8:20 AM

you're calling out so a db trigger fires a call to a http endpoint having access to the same db the event triggering it originated from?

akashra•9/15/24, 8:21 AM

I'm trying to figure out how you've ended up in a situation where you have hundreds of queries needing to be executed as the result of any single event, such that they can't be batched - unless they're a synchronous chain

oof2win2OP•9/15/24, 8:22 AM

it doesnt have access to the same db
