Hi, is the performance between getting data from KV versus from D1 neglible ? (assuming the DB lookup is a find on PK)

S

staticmedia•7/15/23, 7:20 AM

I'm building on a website that caches all the data from the headless CMS on cloudflare using KV. When the DB has an update a webhook pings the worker and updates the cache. The website makes requests to the same worker that fetches from the cache, and hydrates the HTML before sending back to the user

S

staticmedia•7/15/23, 7:21 AM

Because KV doesn't provide cache tagging its quite difficult to manage the cache (with nested data and making sure those nested items stay fresh). I want to store the cache in a D1 so I can more easily lookup data that needs refreshing

T

Tony Leung•7/15/23, 1:41 PM

I'm pretty curious about this: KV is not transaction-ready, is D1 transaction ready? If I have an user from US made a request to my page function using D1 in APAC, will the request take longer? Is there any worker+D1 replica in US which can handle the request for me? If there is and D1 supports transaction, will there any penalty on performance or request time?

vassbence•7/15/23, 2:47 PM

D1 is single writer multi reader (or at least will be)

V

vassbence•7/15/23, 2:48 PM

but KV and D1 are entirely different products for different usecases

theLaCzar•7/15/23, 11:55 PM

quick question, i designed microservices with 1ms : 1db design, however, we are limited to 10DB currently per account, knowing i have several sites under my account, so i guess i have to fit them in, my question is does D1 experience the same issues with normal relations db like table locking, running out of resource etc?

T

theLaCzar•7/15/23, 11:57 PM

because if D1 is efficient enough that table locking is not much of an issue, i guess ill go with a monolitic DB design and lots of workers

You can have multiple concurrent readers. Reads don’t block.

no such table: main.[table001]?

No I'm not querying the 'main.' in SQL at all. I have a build data script that drops everything and rebuilds the database from scratch.

I assume this is the correct command to see locally?
