That’s wonderful ahah I wish I had that before so I could realize I had a 6s+ query every hour, which read 42 million rows.

Does D1 support (or will) streams?

d1-database

Sameer Ali•8/30/23, 6:45 PM

I think that is different question than mine. I am trying to see if i can stream the response from SELECT query directly to client instead of loading the result in worker memory. let's say i have a query that returns large amount of data, which is over the worker memory limit of 128MB, streaming the response without loading into buffer would be only way to workaround worker memory limit.

but main priority is d1-database

Sameer Ali•8/30/23, 7:12 PM

Thanks. It is must thing to have for many use cases. But it can wait.

itsmatteomanf•8/30/23, 8:17 PM

People, use indexes OMEGALUL

itsmatteomanf•8/30/23, 8:17 PM

itsmatteomanf•8/30/23, 8:21 PM

Yeah, they do, but given my volume of reads... it makes sense to improve them.

itsmatteomanf•8/30/23, 8:23 PM

Yeah, of course it's a tradeoff. One is required to be an index, the other might not make sense.

Unsmart•8/30/23, 8:25 PM

Using a NoSQL db it would be 1 write 1 delete and most auto delete a ttl

itsmatteomanf•8/30/23, 8:26 PM

But it wouldn't work well for my use case. I like NoSQL, but it's not always the best.

Unsmart•8/30/23, 8:26 PM

I wasnt even talking about your usecase cuz idk what it is but Leos would

Unsmart•8/30/23, 8:28 PM

If DOs had TTL on keys it would be better priced than kv but you would have to set an alarm so there it would still be multiple writes in weird ways lol

itsmatteomanf•8/30/23, 8:31 PM

Yeah, SQL is nice for those things.

Unsmart•8/30/23, 8:32 PM

Yeah KV has ttl so you wouldnt need to cron and actually afaik those deletes are free

itsmatteomanf•8/30/23, 8:33 PM

You could honestly avoid the expire index, tbh. If it takes a few milliseconds more in a cron it's totally fine.

itsmatteomanf•8/30/23, 8:33 PM

D1 is actually impressively fast.

Original message was deleted

Matt Silverlock•8/30/23, 9:06 PM

At those rates will you ever exceed the included read & write usage in the $5/mo plan? Feels like the wrong kind of optimization.

Anybody have some links to a blog post or github repo that sets up SvelteKit with D1 (using Wrangler?) for both local dev and prod? I can't seem to find good material anywhere and would love to test out D1 and some other CF offerings, but the local dev situation seems a bit complicated

no problem, @ me with a question if you had any because there isn't much documentation regarding this aspect and I had to work most of it out myself

riskiidrus•8/31/23, 8:19 AM

Hi, I wanted to ask about the reliability of D1 in case I ever need to add a new column to a large table.

Let's assume I have a "users" table containing 1 million rows. One time I wanted to add a new column to the table. Is the process as fast as I imagined?

Although I have never experienced something like that before, I will definitely experience it someday. And it's probably not just me.

itsmatteomanf•8/31/23, 8:22 AM

Adding a column, which is empty at the start, is very fast on any SQL database.

itsmatteomanf•8/31/23, 8:22 AM

You'll then need to do up to a million writes to fill it.

riskiidrus•8/31/23, 8:29 AM

Thank you for your answer. I was very relieved to hear that.

But when can we use D1 for production? I'm really looking forward to it

Does anyone know how you're supposed to run Drizzle Kit migrations on D1? https://orm.drizzle.team/kit-docs/quick

Elliot Hesp•8/31/23, 9:31 AM

No issues making the migration, but I'm not sure how it's going to connect to the DB outside of the wrangler / fetch handler
