What's the current best way to handle shipping logs from durable objects to a custom destination? Specifically I'd like to just use a custom logger i have and ship the logs after responding to an RPC without holding the response to the invoking worker (plz ping me)

Maybe tail workers? I'm not sure if they respond to RPCs to DOs as an exclusive event

Interesting in patterns around this as well. I want to ship to axiom.co. Shame they acquired and broke Baselime (just flat out doesn't work), but their analytics engine I think is the replacement, and similarly based on clickhouse, I'd be curious if that became the central sink and from there you could have forwarders push, or pull somehow

I flush logs to axiom at the end of each request. Since the DO persists until it’s done processing regardless of inbound RPC calls, just run the flush async without the await.

Hey Lambros, was wondering if the team got back to you on this

Regarding the behavior of setting an alarm and throwing right after, I will check with the team and get back to you.

Providing a more fleshed out example to better-communicate what I'm asking - hopefully it makes sense

export class MyDurableObject {
    constructor(state, env) {
        this.state = state;
        this.env = env;
    }

    async alarm() {
        console.log("Alarm triggered");

        // Will this alarm be set? or would it be "overriden" by the retry of the original alarm
        await this.state.storage.setAlarm(Date.now() + 150000);

        // Call a method that fails
        await this.failingMethod(); // failure
    }

    async fetch(request) {

            return new Response("Alarm scheduled.");
        }

        return new Response("Unknown command", { status: 400 });
    }

    async failingMethod() {

just try it?

Original message was deleted

sathoro•2/9/25, 9:05 AM

other storage operations don't get rolled back. and I assume the alarm doesn't get "rolled back", but rather the exception overwrites the alarm when the retry logic is kicked in (which will trigger the alarm 2 seconds later)

S

sathoro•2/9/25, 9:06 AM

my assumption (I could be completely wrong here), is that it would be virtually identical to if you wrapped the alarm in a try..catch and then manually called setAlarm for 2 seconds later in the catch. that would "overwrite" any previous setAlarm call (minus the specific retry logic cf does)

S

sathoro•2/9/25, 9:08 AM

we do lots of background processing and queues with DOs and we almost always wrap the whole alarm handler in a try..catch and do custom retry logic. the default retry logic is not ideal in almost any real-world scenario

The DO will remain as long as it has storage attached (it may go idle but the storage will persist). If you don't need the DO any more you can do a deleteAll() on the storage and then once idle the DO will be terminated.

lambrospetrou•2/9/25, 5:45 PM

The approach I like to think about Durable Objects, and suggest others too, is to stop worrying about "managing the Durable Objects themselves".
When you need them, you just reference them, and they will magically appear. You don't ever delete DOs. By deleting their storage you just stop paying for storage. Even after

deleteAll()

deleteAll()

, you can reference the same ID and get it running again.

Obviously, without any storage used a DO is stateless so its ID doesn't matter much other than for a few seconds before it hibernates again, but it doesn't change the fact that you should not think in terms of creating and deleting DOs.
You delete the storage to not pay for it, not to delete the DO. That's just an implementation detail.

This is also what some literature refers to as "virtual actors", they always exist and are always addressable.

What does "forget" mean though? I cannot give an answer as generic as that. If a resource has been deleted from the rest of your application and not the DO storage, then you should have a trail of the deletion somewhere in the system, and maybe even do a crawl after the fact to clean up or something.

Hmm, I didn't advise against using the list API. I advised against using it as part of your hot path in your application logic. If your application is designed in a way that you have to iterate all DOs in a namespace, or thousands of them, and you are not necessarily accessing their data to serve that query, then the architecture of the application is wrong.

Ok, that makes sense. I was also just trying to put myself in the shoes of someone who may not have familiarity with the platform, or that they should be architecting their app for autocleanup/storing IDs somewhere.

I still don't agree with this. Autocleaning are very different things from storing IDs.

You almost always want to have a way to get the DO ID from within your application. You cannot always trust users telling you which DO ID they have access to, you need to serve List APIs, and hundreds other use cases. Even if don't store literally the DO IDs, you should have a deterministic way of generating that ID. Otherwise it's a black hole. Like any other storage product, when an entity/account/resource will be deleted you need to do cleanup. Same applies for R2, for DOs, for SQL databases when the IDs are random, and the list goes on.

Autocleaning, not sure where this fits. Maybe just for temporary ephemeral data you want to delete after a TTL, but again, there shouldn't be magic, you design around this deletion.

Maybe it's just me, but I don't want providers to be deleting my data on their own or through something I didn't explicitly configured/coded.

By Autocleaning, I mean like scheduling an alarm that deletes everything stored, if it hasn't been renewed before then.

As an example, in a few of my apps, I use a DO as a more secure cookie. I.e., while the client just sees an opaque value stored, I can ask the DO corresponding to that opaque value, and it returns a user id, their expected user agent/location, etc.. However, because cookies themselves don't persist forever, I want to ensure that the DOs don't stick around forever either, as that would cost me money for no benefit. Thus, I set an alarm for the time that the cookie would expire, and then on every call to the DO, I reset the alarm. If the alarm fires, it deletes all of its storage, so that I'm no longer billed for it

I don't know if this is the way

you are supposed to go about this kind of work, but it seems to work ok for now

Hard@Work•2/10/25, 12:21 PM

For the above case, while I could store every ID I've ever used in a second database somewhere, if I do that, I might as well just not use a DO, and store the metadata in that database.

probably cheaper and more efficient to just auto delete after some long period like a few months rather than writing to the alarm every single request

by "their own worker projects" do you mean making envs per PR / per person? that seems like it would blow up your workers dashboard.

i'm also curious if there are best practices here or if this is what cloudflare does internally?

lambrospetrou•2/10/25, 12:28 PM

Yeah, in this case you are literally talking about ephemeral data. So, setting a TTL for the alarm long enough ahead in time to do the cleanup is the right thing to do. How short or how long you do that it depends on the strictness of your application.

Well if it's tens of extra projects, it's not a problem. If it's going to be hundreds of thousands then yeah it won't be nice experience. We use separate projects for each of our envs in some teams. Keep it simple.

No, although I am not sure I understood your full issue. In our case we don't deploy per PR. We only deploy after PRs are merged to a staging env, and later in production. So we don't have multiple PRs modifying the same workers.

Also, if you are worried about too many script projects, you can extend your CI to delete the deployed workers/DOs once a PR is merged and closed. So you will only have as many projects as your open PRs.
Just something to think about too, if you like having the whole infra per PR.

ok, thanks. While I have you, I had a couple more questions:

1. for migrations, are you supposed to just have a running changelog of all tags? Or do you delete them after there are no more references to deleted/renamed classes?
2. Do wrangler.toml files support dynamic envs? Like if I wanted a user specific env or a PR specific env, can I have like [[env.$USER.durable_objects]] or something like that?

anyone? From cloudflare? Please reply
