Indexes will add an additional written row when writes include the indexed column, as there are two rows written: one to the table itself, and one to the index. The performance benefit of an index and reduction in rows read will, in nearly all cases, offset this additional write.

"Each isolate has some built-in flexibility to allow for cases where your Worker infrequently runs over the configured limit. If your Worker starts hitting the limit consistently, its execution will be terminated according to the limit configured."

Is it possible to use the results of a previous query in a

d1.batch

d1.batch

call in the next query? I'm worried that sending a read query to find a specific row, waiting for the results in JS, and then sending a write query may end up with 2 workers trying to edit the same row.

discondition•8/27/24, 9:34 PM

What latency are you guys getting?

I don’t what to expect but my Remix worker that calls out to my DB is taking 300-400 ms for really simple queries. This ain’t good enough for what I want really, hopefully there are ways to speed it up. I have the smart location switched on.

James•8/27/24, 10:34 PM

Neon is Postgres which is much more versatile than SQLite in my opinion and what I’d generally recommend personally

James•8/27/24, 10:35 PM

We use neon + workers, with Postgres.js very successfully. What are you building though? Maybe SQLite makes more sense?

o7•8/28/24, 2:13 AM

This isn't a map of D1, but it's a map of DO and D1 is based on DO so it might give u a little bit of an idea where your DB is

Tracking where Durable Objects are created, wherever you are in the world.

o7•8/28/24, 2:16 AM

I may or may not be 800km away from my DB, getting under 100ms with the smart placement being local. Sometimes when the smart placement works (enough traffic) I get around 70ms

discondition•8/28/24, 2:20 AM

Thanks, I guess I gotta look into optimistic UI

Ttoadfans 200-300ms

Max (@rozenmd)•8/28/24, 5:41 AM

where are you based? D1 is still subject to the speed of light, so 200ms round-trips between australia and usa are a thing

Is there a way to lift the "Maximum Length Of A LIKE Or GLOB Pattern"? I'm running into "Error: LIKE or GLOB pattern too complex: SQLITE_ERROR" when the pattern exceeds 50 characters.

Trad•8/28/24, 9:47 AM

hi everyone, I am planning to use Honojs with worker and d1 database for my new project.
There are two topics that I would like to get opinions about this project. I plan to get millions of reservations when I will keep data for tourism businesses.
Is D1 Database the right choice for this?
If D1 is the right choice, is there a way to provide IF NOT EXIST control when I add a column with the ALTER TABLE command? I am writing the database structure in .sql format on the local and I am migrating remotely and locally with wrangler.

Seems like D1 doesn't support `ATTACH DATABASE` command to aggregate from multiple D1.
