Hie there I am using Cloudflare D1 for a project and i noticed the latency is really high around 800 to 900 ms.
resulting in overall high latency in api calls. The DB is deployed in APAC region and the worker is in colo=DEL.
Any insights on why this could be Happening?
Thanks

think we just used the types from the HTTP API here

Does that mean I can just assume successsuccess is always truetrue and not check for it?

within the Worker, yep

BurritoOP•11/16/24, 5:12 PM

Got it, probably a good idea to have it documented though.

Xxiaoyu2er hi i have a question, is kv faster than d1, is there any official benchmark? i ...

James•11/17/24, 9:38 PM

They have very different use-cases. That benchmark is a bit out of date with https://blog.cloudflare.com/faster-workers-kv/ now, and KV getting even faster, but it’s going to really depend on your application.

Lots of write-once read-often key-value data? KV makes a tonne of sense. Lots of deep relational data, D1 makes more sense.

James•11/17/24, 9:39 PM

If you can describe your app and the kinds of data/queries you’ll be doing, we can probably provide better recommendations

James•11/17/24, 9:41 PM

It’s also pretty common for apps on Cloudflare to use both, as well as R2, etc, again just depending on the kind of data you’re storing and how you need to access it.

Chaika•11/17/24, 9:50 PM

D1 perf is going to be hard to measure as its a single durable object/instance running in a single region where KV is two central stores (US, EU) + heavy caching in front

Hi all. I am really often getting {"D1_RESET_DO":true}{"D1_RESET_DO":true} error when trying to import db using https://developers.cloudflare.com/api/operations/cloudflare-d1-import-database

nejc•11/19/24, 5:46 PM

any insights into what could be going on?

Max (@rozenmd)•11/19/24, 8:01 PM

no - the bookmarks time travel uses are like pointers rather than actual copies of the DB, makes it hard to do stuff like that

i initially wanted to build a Time Machine style UI for it, but it wouldn't work

Nnejc any insights into what could be going on?

Max (@rozenmd)•11/19/24, 8:06 PM

that's a pretty bad error on our part, if i had to guess it's hitting an error and rolling back, does it work if you call the /query API with the sql text directly?

nejc•11/19/24, 8:30 PM

@Max (@rozenmd) problem is that this DB is giving error all the time

I think the D1 was out of beta few months back, still these issues regularly.

Max (@rozenmd)•11/20/24, 9:20 AM

There was a bad release at 08:42 UTC, we have since rolled it back.

I've noticed that my d1 has become really slow.

A simple query where i loaded client information took only 20ms, where now it takes almost 300! i didn't change anything. we have multiple tenants, and this can be seen on the dev env and the prod env

Edit: All DBs are hosted in WEUR, where all our tenants are. smart placement is enabled for worker

Abdul•11/21/24, 6:14 AM

My startup recently got funded, and since i am cloudflare boy, i am already using majority of its services now i was thinking wether i should also use D1 as my main Database or not?

-> why i was thinking of D1?
= Since i am going to use workers for API and smart placement is also available, so using D1 would bring my api and Database closer making the query load faster.

-> Does D1 has limitations for startups?
-> has anyone faced problems with it and decided to change their DB

My use case ( not exact, just a example )
-> User will have multiple relationships in the table
-> Analytics

Thats it. please guide me if you can from your experience.
Thank you

when you say it takes almost 300, do you mean as measured from the Worker? I don't see evidence of that kind of performance regression in that DB

also, how much traffic is this DB doing? smart placement relies on steady traffic to place your Worker optimally

SteffTek•11/21/24, 11:47 AM

yep, i measuered the time within the worker. it always was around 20ms before.

should i disable smart placement? database is in WEUR anyway and all our traffic (should) come from germany

SteffTek•11/21/24, 11:50 AM

dashboard doesnt show any smart placement traffic, only default placement, so maybe not enough traffic

Max (@rozenmd)•11/21/24, 11:55 AM

smart placement uses 1% of your traffic to compare timings (so 99 get smart placed, 1 is left default placement as a baseline), it sounds like it needs a bit more traffic yeah

SteffTek•11/21/24, 11:56 AM

im just wondering because even our tenant has this problem where traffic should exist, more than our dev deployment ever had even while testing

SteffTek•11/21/24, 11:57 AM

funny thing to say: "yeah you just need to use the app more so it becomes faster" lol

lambrospetrou•11/21/24, 12:26 PM

Can you check your placement status for your worker? https://developers.cloudflare.com/workers/configuration/smart-placement/#placement-status

I think you also need to do multiple roundtrips from your worker to the database, otherwise it cannot get much faster anyway if it's a single request.

nejc•11/21/24, 12:27 PM

lambrospetrou•11/21/24, 12:30 PM

It's not doing more requests. It just uses 1 out of a 100 of your requests with smart placement disabled, so that it can compare that with your other 99 requests that are smart placed to figure out if it's worth it doing the smart placement or if it should "smart place your worker" elsewhere.

But always check the placement status to see if you are actually smart placed.
