I've been working on analytics for D1's queries on the side, starting with wrangler, you'll be able to find your slowest or most expensive queries by rowsRead/rowsWritten

An extremely early preview build of it is available here if you're curious: https://github.com/cloudflare/workers-sdk/pull/4909

Today it uses averages, but on Monday I should have it using sums, so it'll be sorted by queries that run most often.

It depends entirely on the index and the query!

Hey!
Is there an estimate of what should be the expected per-db storage limit after the beta is over?

2GB would be way too low for any production application, and i understand it will probably be increased, but i'd like to know how high is it expected to go, as i know that the intended use case is "one db per user" but we expected to use it as a normal database.

Natan Parmigiano•2/2/24, 8:09 PM

is there any way of "dynamically binding" a D1 database?
I cant see a way of applying the idea of using D1 in a multitenant environment without needing to manage a worker deployment for every customer..

For this to happen will Cloudflare does horizontal scaling automatically in the background or are we supposed to do it manually?

Matt Silverlock•2/3/24, 8:47 AM

Then the rows scanned will depend on how the query uses the timestamp and the index. I strongly suggest reading https://developers.cloudflare.com/d1/how-to/using-indexes/

if by production you mean when D1 becomes Generally Available - I don't know

yes - via the API they create a new D1 db and update their Worker bindings for each new db. The UX is currently very rough.

we're bound by durable objects' RPS limit, the API gateway has a separate rate limit
