hi - any github example for a worker project with d1? need to build for mid-size project and a good example on how to structure the code would be great to start

RRob M.Look at this one: https://www.sqlite.org/fts5.html

Santosh•11/28/23, 2:03 AM

How do we use this on D1? An example would be perfect, not many of use SQLLite at work.

Village (Josef)•11/28/23, 4:59 AM

Two questions

Are all the limits except the DB size limit available to be potentially raised?
Is it feasible to make a DB per customer with D1? I.e. is there some way to dynamically set up bindings and such without having to manually put them all inside wrangler.toml and without incurring insane startup overhead or having to route through the API? (That was a lot of or’s sorry)

kian•11/28/23, 5:31 AM

Are all the limits except the DB size limit available to be potentially raised?

You'd need to be specific about the individual limit in question, but generally they aren't raised on a per-user basis and instead are global limits.

is there some way to dynamically set up bindings

Not currently.

guys can anyone tell me how i can use two d1 databases in a single worker?
i tried this in the toml file
name = "weathered-queen-4070"
main = "src/index.ts"
compatibility_date = "2023-10-30"

[[d1_databases]]
binding = "DB" # available in your Worker on env.DB
database_name = "dogpark"
database_id = "xxxxxxxxxxxx"

binding = "DB2" # i.e. available in your Worker on env.DB
database_name = "adminportalDB"
database_id = "xxxxxxxxxxx"

but then i get the error that Can't redefine existing key

/Users/apple/Documents/weathered-queen-4070/wrangler.toml:10:14:
10 │ binding = "DB2"

oh thank you.

rodrigo•11/28/23, 8:55 AM

I understand when read replicas are implemented there would be one master where all writes take place, right?
Is there any plans to have multiple write masters, based on table partition (for instance)?
Imagine a User table, where users write their own data. Would it be possible to partition this table based on location?
I mean, to create a partition of this table for each location (america, europe, asia) that would become master for writes, and this way a user would write as master to the partition in its location (and then read replica would replicate it to other locations)

VI•11/28/23, 9:48 AM

Since d1 uses SQLite internally, does it run into the same limitations as SQLite, namely handling large number of independent writes/sec. From what I read SQLite is not capable of handling more than 1000 write reqs/sec.

Currently for open beta, ~1K QPS depending on result set size. Our eventual goal is to get 3-10K QPS for reads, 1-2K QPS for writes. Let us know what requirements your workload would need?

Can you promise at this point that the D1 size limitations will begone

janat08•11/29/23, 8:52 AM

You recommend against building on D1 for production, but surely not because you still have forseeable hard limits on db size?

Do you get to shard it or something once at the ceiling. You mean I won't be able to have a petabyte db on cf, but my question is if at some point I'd have to close registration at my app because of the storage limit?

Hello, I’m Allie!•11/29/23, 9:04 AM

I think it is also a case of understanding what platforms are built for. While it would be nice theoretically if D1 could scale infinitely, in practice, if you do get to Petabyte scale, you should probably look at a DB specfically built for that. Until then though, D1 is a good choice

janat08•11/29/23, 9:22 AM

Is there going to be some library for sharding, where you can have multiple d1 dbs, and get to treat them one, so as to bypass the size limitation at the expense of extra reads

Max (@rozenmd)•11/29/23, 9:28 AM

we have folks building products that have 1 db per customer, where each db has the same schema, just stores different data
though migrations + dynamically binding to new dbs are a pain point

Max (@rozenmd)•11/29/23, 9:40 AM

It doesn't sound like D1 fits your use case if you're worried about petabyte scale. Hyperdrive is probably a better fit: https://developers.cloudflare.com/hyperdrive/

janat08•11/29/23, 10:38 AM

I have no reason to worry about petabyte scyle, but surely anyone is hitting the 2gb limit

kian•11/29/23, 11:04 AM

This is a beta-only limitation. The D1 team will increase the maximum storage per-database, storage per-account and number of databases for Paid plans during the course of D1’s public beta.

kian•11/29/23, 11:05 AM

They're beta limitations - there is no forecasted hard limit, but there will naturally be one even in GA.

after successfuly inserting into the table (I can see the values in the UI) if I try to edit / insert from the ui or with code i get the error FOREIGN KEY constraint failed (Code: 7500) , and If I try to delete the whole table from the UI Its telling me to try again later (its the same for two days)

talfiz•11/29/23, 4:19 PM

I believe its a bug

Max (@rozenmd)•11/29/23, 4:21 PM

the dashboard doesn't support editing binary

I dont try to edit the binary I try to edit a completly diffrent table

talfiz•11/29/23, 4:22 PM

Its the same message for all the tables

Even tables with no binary

Rob M.OP•11/29/23, 4:41 PM

Can you send a snippet with your "env" usage?

Rob M.OP•11/29/23, 4:44 PM

By the way, you should use 'context.env.*' instead of 'env.*' in Page workers. Maybe that's the issue.

talfiz•11/29/23, 5:56 PM

Hi guys I fixed the bug what I tried to do is to delete a user when a teacher is still refrenceing him to do that I should add ON DELETE CASCADE to the table thanks for however tried to help

You talk below about cases where people create 1db per user.. But to be more efficient, if I want to create 1 db per region (enam, wnam...) and redirect each user to the closest/fastest db, is there a way to programatically do that? with the CF-IPCountryCF-IPCountry header ? but should I build a table with states on the east/west cost ... and redirect based on it? or is there a way to get a ping to the D1 center location?

rodrigo•11/30/23, 9:59 AM

And regarding Asia-Pacific region .. that is a region too big (Australia, China , India ...). Is there (or will there) a way to allocate D1 dbs to smaller areas within the region?
