Making JOIN Task Async failing some workflows

[vamsibandarupalli]

Describe the bug
After making JOIN task async some workflows are failing to execute successfully. JOIN task is failing with timeout. If workflow have DECISION tasks in FORK_JOIN branches JOIN whole workflow is failing cause JOIN task is failing with responseTimeOut error.
In the below provided workflow "mock_task" Task definition has 300 seconds timeout but failing even before JOIN starts.

To Reproduce
Steps to reproduce the behavior:

1. Use the above given workflow and task definitions to reproduce the issue
2. Use this input for workflow
   {
   "body": {
   "text": "101",
   "version": 3,
   "logicalId": "lid://demo-products.1",
   "page_number": 1,
   "page_size": 20,
   "userContext": null,
   "filters": []
   }
   }
3. See error

Expected behavior
Expect JOIN task to run without error.

Additional context
When started workflow JOIN task scheduled is next here. JOIN is getting scheduled even before updating the taskUpdated time, so JOIN task is failing this check here and timing out.

I'll try to debug and will raise merge request if found anything.

@vamsibandarupalli there is also a pretty big performance issue that was introduced around JOIN in the newer versions of Conductor. See the discussion here: #3436 (reply in thread)

Which unfortunately, isn't getting much of a response from the maintainers/community here :(

[v1r3n]

#3594 addresses this.

[Holmesus]

There is still this problem...

[v1r3n]

There is still this problem...

Hi @Holmesus can you provide more details?
