D1 is built on SQLite. So it's actually not running at all when it's not being used. SQLite also makes spin-ups near-instant though.

kelbs•3/18/24, 5:23 PM

Turso claims 500ms latency to start up an inactive sqlite db on their system. Maybe there are differences between that and D1 though e.g. they're using libSQL

Isaac McFadyenOP•3/18/24, 5:27 PM

So one of the differences between Turso and D1 is that Turso actually runs a server for serving SQLite queries using libSQL as you said. D1 directly accesses SQLite on the node where your data is stored so the latency is basically the amount of time to open the DB and actually run the query (plus the time to get to the node where your DB is of course).

I

Isaac McFadyenOP•3/18/24, 5:28 PM

I believe Turso actually runs on Fly.io Machines so that would explain the spin-up latency.

K

kelbs•3/18/24, 5:29 PM

Gotcha, thank you. Would like to compare query latencies between the two if I can get everything hooked up

I'm trying to get my local d1 database from one local project to another local project, i.e., from one dir to another dir without re-running the

wrangler d1 execute --local --file=.sql

wrangler d1 execute --local --file=.sql

wrangler d1 execute --local --file=.sql

wrangler d1 execute --local --file=.sql approach. I thought I could just move the

.wrangler/state/v3/d1

.wrangler/state/v3/d1

.wrangler/state/v3/d1

.wrangler/state/v3/d1 dir over to another dir and spin things up but that did not work. Is there some other approach I could use?

My problem is that I use a separate worker to load portions of the database and I was hoping to avoid moving that worker and its config over to another dir temporarily to get the database fully loaded.

Thanks!

Given the max row size of 1MB, is there a good pattern for breaking a large blob or JSON string across multiple rows if larger than 1MB? Reconfiguring all my statements to handle this (rare) situation seems painful. Best to just fail/reject in that case?

M

Matt Silverlock•3/20/24, 12:52 PM

How large are your blobs? You could also write to R2 and reference from D1 - especially for large large blobs / multi MB blobs. No different from an image or binary data in that way.

J

Jason Hostetter•3/20/24, 12:57 PM

Yeah the issue is I guess it's technically unbounded. Vast majority are fairly small, but some object types can be very big. I have a mechanism for storing large data in R2 with a reference for other columns so I think that is probably the best solution here too. Just wanted to make sure there wasn't some other pattern to take advantage of that would preserve JSON queryability.

M

Matt Silverlock•3/20/24, 1:13 PM

You could always split across multiple rows - you’ll eat some query and insert complexity but you can still use JSON functions across rows.

The dev experience for SK + D1 was rough, so I tried this route. I'll try again. https://developers.cloudflare.com/d1/examples/d1-and-sveltekit/

If you have 4 indexes it will write 5 times (row + 4 indexes)
