How do you choose between durable objects and r2? The docs don't say much about DO.
JHello! I am trying to change the Content-Length header, as I will use Cloudflare Workers to download files from a R2 bucket. I tried by changing the header manually, but it doesnt make a change. Then I read that it was not possible to change that header, and that the only way to do so is by using Streams.
Now, my question is how should I do that? I tried to do it (see the code below), however it does not work. Any advice is very much appreciated!

QThis is the doc that I specifically didn't find useful. The DO section didn't really tell me when I'd use it over R2. I feel like you need to already know what the company had in mind for DO before you use it. Like maybe it's some kind of popular storage design that I'm not familiar with, so I don't know what it's for.
DI am using a worker for server-sent events. Basicall it reads from a database every 3 seconds and sends the results via SSE to the client. Now if I understand correclty, the new standard pricing will neither evict quickly (like the old bundled plan) nor will it be high duration costs (because only cpu time is important) right?
CR2 is better for bigger files as it has the largest storage size. DO is good when you need all the data to be synced across the global.
AEviction can happen on any plan but usually doesn’t happen unless there’s a Cloudflare update (about once a day in my experience), free plan users get evicted more frequently than paid/Enterprise. And yes it’s charged in CPU milliseconds instead of wall time.
DThank you 
.For a worker route, if you don’t setup any rate limiting
.What’s like the, default rate limit set to
KFree is 1000 reqs per min
KPaid doesn't have one (that limits the whole Worker)
QThose don't seem related though. 
What if I need small files (~2kB) that serve more as debug logs and will rarely-to-never be accessed?

HI would still go for R2. DOs are more for when you need compute attached to storage
KDurable Objects are stateful Workers that have transactional storage attached
KR2 is just object storage, strongly consistent with an S3 API
KBy far the simplest to use, since the S3 API means you can interact with it outside of Workers/the CF REST API
QI'm only using Workers to write the data, but I don't intend to read much from it.
QBut "compatible with S3" doesn't really mean much if I'm not using S3.
KMeans you can back it up easily, interact with it outside of Workers (i.e your own device), migrate to other storage options easily, etc
KIt's not about you using S3, it's about how many things integrate or work with the S3 API
QDon't both R2 and DO advertise as strongly consistent? If that's not a tie-breaker between them, what is?
QI'm not currently using, nor going to use, anything that integrates with the S3 API, so this doesn't help me choose between them. 
QThe limit page is a bit better than the differences page. 
Looks like R2 is for just dumping data into it [free tier + unlimited storage]. DO says it's a paid-only feature that limits you to 50GB for your entire account.

U50GB is the initial account limit easy to raise
DI would go with Wasabi or Backblaze.
.ok thanks
JWorkers doesnt allow to change the content-length header or what?
KWhy would you want a custom Content-Length header? 
JI wanna use Workers to act as a middleman (for auth) between R2 and the client. The client is a machine that requires the files we store in R2.
JI wanna send those files once the client gets authenticated. However the client wont download the file if the content-length header is not correct
JJif you curl it, you can see the content-length is 15
JHowever, it should be 175104
CI'm seeing the file contains
[object Object] are you sure the file was uploaded to R2 correctly?KYeah, that wasn't uploaded right
JThats just the body
JTry it in a browser
CThat's how I got it
KBrowser or not doesn't change what the body is.
JI can download it without any problem from the browser. It doesnt show [object Object]
CTry opening the file
J
JIts a binary, why do you wanna open it?
KBecause it isn't.
KIt's text, that says
[object Object]KIt wasn't uploaded properly, the binary isn't there
JYeah
Jit was just me trying something
