Max (@rozenmd)•10/10/23, 1:19 PM

what you're seeing is the difference between how long d1 took to execute your query, and how long it took to go from request -> query -> response

Max (@rozenmd)•10/10/23, 1:19 PM

we return just the query response time, since that's controllable by the user (request less data/index your tables etc)

nothing measurable, so at most a couple ms - and the queries drizzle generates are now pretty efficient too, so in some cases it might be better on the DB site if we don't hand-write everythign

Hi!
An assigned UUID to a D1 database will stay the same forever, even if we move from Beta to GA, or if we need to uses Time Travel ?
To give some context, I'm asking because as the concept of database-per-user use-cases will be soon possible (only manual bindings in wrangler.toml for now and limited to ~5K), I suppose the future dynamic binding will uses the UUID assigned to the D1 database. Then, we want to save this UUID in other databases, and want to be sure this UUID will never change later, we could even consider it as a replacement of a classic id_customer field.

Isaac McFadyen•10/10/23, 3:21 PM

Time travel = yes, stable UUID
Alpha -> Beta, not stable, because you need to recreate the database
Beta -> GA, probably stable, an employee has said here before that there shouldn't need to be any migrations involving recreating of databases. Ref: https://canary.discord.com/channels/595317990191398933/992060581832032316/1153997053861576744

Isaac McFadyen•10/10/23, 3:21 PM

But D1 is in beta and no guarantees are made. If something goes wrong or DBs need to be migrated the UUID may change.

If you need performance, write a Worker then talk to it over HTTP from python

andyt•10/10/23, 6:58 PM

ah ok, how do you create a local d1 database and script it?

Cretezy•10/10/23, 9:05 PM

Why is the D1 HTTP API lower performance than the API in Workers? (excluding that it's not in the same datacenter)

Original message was deleted

Cretezy•10/10/23, 9:10 PM

That's the "(excluding that it's not in the same datacenter)" part, but it seems like the API is quite slow, even for remote

Cretezy•10/10/23, 9:12 PM

I'm seeing 500-700ms for simple queries

Max (@rozenmd)•10/10/23, 9:12 PM

The API isn't designed for Workers-style access patterns, it's an API

Max (@rozenmd)•10/10/23, 9:13 PM

whereas a Worker will be within 50ms of 95% of the internet-connected world

Cretezy•10/10/23, 9:15 PM

But why isn't it designed for this? Multiple queries in a Worker is <100ms, a single of those queries outside is >500ms. They are designed for Workers, but the API being 5x slower seems like a missed opportunity

Cretezy•10/10/23, 9:15 PM

The alternative is making a query worker such as http-api-d1-examplehttp-api-d1-example above, but it feels like the API should be able to do that

itsmatteomanf•10/10/23, 9:27 PM

This, and also the core datacenter might be distant from the D1 location, which adds to the roundtrip time.

itsmatteomanf•10/10/23, 9:27 PM

You are generally close to the database you create, so it's fast you -> worker -> db.

itsmatteomanf•10/10/23, 9:28 PM

If you use the API you do you -> api (possibly far away) -> worker (it's an assumption, but I bet it's a worker or similar) -> db (close to you).

itsmatteomanf•10/10/23, 9:29 PM

This makes queries at least 4x the time to go from you to the API, plus inefficiencies as connections need to be established.

Max (@rozenmd)•10/10/23, 9:42 PM

How to select the most recent day's data from the database?
The database content is as follows:
id ip UA time
41 139.162.86.143 Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/117.0.0.0 Safari/537.36 2023/10/7 09:40:22

Can this be done?
SELECT * FROM m_table
WHERE time >= DATE_SUB(NOW(), INTERVAL 1 DAY);

so we will use python -> call HTTP request to worker -> worker handle d1 db logic?

like this
