niiiiice

yeah, filters.

I figured, workers have a memory limit of 500MB

so I was like, this data doesnt need to scale so the 'single thread' bottleneck wouldn't really apply

the issue is that the actual persistent mechanism limits values to 30kb which is incredibly small

so im kinda confused on how the data should be organized with such small key/value pairs

I mean its possible its designed this way intentionally to remind developers that durable objects don't really scale well as individual objects, but I am not really sure I get the point of durable objects I guess.

I mean originally I thought this pitfall was addressed through the ability to run compute directly on the worker, ie, querying/sorting the data before returning it, etc.

but that still doesn't explain the correct way to store say, 500 1kb documents in a single durable object

Within Cloudflare, KV might be the closest, with no limit on number of keys and key formed with period filter in mind (something like user:period:transactionID). But maybe other providers suites best.

Nice! It looks like I’m only getting the log entries after a request is finished. Which for a web socket connection means only after the session. Is that the expected behavior?

fair enough but like

whats a valid use case for durable objects?

I mean I understand the latency and consistency advantages but other than that im lost.

the way it was advertised in the blog post associated w/ its open beta sort of implied it was a replacement for databases whereas I am starting to see that isnt the case?

I mean it's a keyvalue DB, there's lots of types of DB

sure, I do see that

so its really just an alternative to the KV store that is less globally distributed and more consistent and closer to the user

ie, lower latency, higher consistency, but worse at scaling?

Nope, still perfect linear scaling

a single object is a single thread

so you cannot simply cram more throughput out of a given object

a given object is limited by the single thread/worker that it runs on?

Where are you seeing the single thread? Just to make sure we're on the same page?

Can't see anything about that on https://developers.cloudflare.com/workers/learning/using-durable-objects
