Converge Threads

Component	Type	Description
Converge Threads	🔀 action	Aggregate data from concurrent threads

The Converge Threads component closes a concurrent-thread section and collects output from each thread into a single list. It is designed to be used after Run Concurrent Threads and receives the results from every child thread that reaches it.

When to use Converge Threads

Use Converge Threads when you need to:

• Collect outputs from all parallel threads into one place
• Continue the workflow with a combined set of thread results
• Inspect which input item and output data came from each thread

Placement rules

• Place Converge Threads downstream of Run Concurrent Threads
• All thread paths should connect into the same Converge Threads component
• Do not place another Run Concurrent Threads inside the region that converges here

Output format

The Converge Threads placeholder returns a list of objects. Each object includes the thread id, the input item that started the thread, and an output object containing all placeholders produced inside that thread.

Example output:

[
  {
    "threadId": "aeeb2999-ba75-430b-afd6-ba05f3318163",
    "inputItem": "aaron@workflow86.com",
    "output": {
      "placeholder_key_a": "value_a",
      "placeholder_key_b": {
        "nested_key": "nested_value"
      }
    }
  },
  {
    "threadId": "9d74b4ee-5e0f-44da-b246-9e199a6176a6",
    "inputItem": "aaron.tran@live.com",
    "output": {
      "placeholder_key_a": "value_c",
      "placeholder_key_c": 42
    }
  }
]

If you need to work with the output as structured data, pass the Converge Threads placeholder into a Parse JSON or Run Code component.
