Delong•6/6/25, 3:59 PM

Hey @Matt Silverlock , I saw your announcement of increasing to 4,500 concurrent workflow run within each account for user that have workers paid, but from the dashboard and what I am seeing, it never reaches 4,500, it get limited at ~120.

Delong•6/6/25, 4:15 PM

So I was observing workflows dashboard this morning, because I made a quite significant changes to my worker last night.

I was expecting approximately 400 instances per minute that are spawned from a parent workflow that are batched into 4 groups, 100 per 15 seconds. I was expecting all to be ran on their given interval. But instead of all been completed, I see a huge number of workflow instances being queued; then it accumulated at least 1 thousand of instances. I observed it on time, and turned off the scheduler 'cron'. Hence stopping the ability to generate more queued instances. I am not sure if there is anything from worker that is limiting the ability from achieving the ideal concurrent instances, or any other reason, please help

Also the workflow dashboard also been extremly slow. And whenever I push any new debugging changes, it failed the build

Dan (Openside)•6/14/25, 3:38 PM

When architecting workflows and steps, what are the pros/cons of using a queue in conjunction with a workflow vs. just running a loop and performing a step. Example: I read from the db a list of URLs that need to be moved over to R2. What would be better architecture: Read in the list, loop through and perform batch steps for each? Or add each one to the queue which then triggers a new workflow for each. Here is what I have come up with, curious to hear what else I should be thinking about.

No Queue (stay within workflow) approach:
Pros - avoid queue pricing; can aggregate results of all of them and then do more processing once they are all done.
Cons - may hit the 1024 steps limit depending on size of list and number of inner steps; all share same workflow storage so may hit 1GB storage limit

Use Queue (run new workflow per item) approach:
Pros - can rely on queue retries; starting new workflow reduces number of inner steps to avoid 1024 limit; allow for 1GB storage for each
Cons - consumes more workflow requests, increasing price; not able to easily process after all files in list are processed. added cost due to using queue.

Anything I'm missing or misinterpreting? Curious how others architect your workflows. thanks

to bad... wont use workflows untill this is sovled

scook•6/15/25, 1:49 AM

Has anyone run into issues locally when invoking Workflows from async
waitUntil
waitUntil
code?
I have a Worker that attempts to trigger a Workflow like so:

// Worker
ctx.waitUntil(
  nonBlockingFunc({ ... })
);

async nonBlockingFunc() {
  const workflowInstance = await env.MY_WORKFLOW.create();
  // await new Promise((resolve) => setTimeout(resolve, 2000)); // sleep fixes???
  return workflowInstance.id;
}

// Worker
ctx.waitUntil(
  nonBlockingFunc({ ... })
);

async nonBlockingFunc() {
  const workflowInstance = await env.MY_WORKFLOW.create();
  // await new Promise((resolve) => setTimeout(resolve, 2000)); // sleep fixes???
  return workflowInstance.id;
}

On my local dev, it appears to successfully create the Workflow instance (I can see the instance id), but the Workflow itself is never actually run. However, if I insert a sleep after the invocation, then the Workflow does actually get run. Afaict this is only happening on my local and not in production.

My friendly ChatGPT claims that this is a shortcoming of Cloudflare local development / Miniflare not fully respecting the async tasks in the

waitUntil

waitUntil

, because it garbage collects the state and tears down the execution environment after the Workflow instance is registered but BEFORE the workflow is actually run. The sleep prevents the premature shutdown of the Worker execution context.

Can anyone verify if this is true?
