Get from Queue logic

Getting tasks from process and node where Queue logic is added.

Get from Queue logic adds in current task:

  • __queue_task_id__ - task ID from node's Queue
  • __queue_task_data__ - json object of task parameters from node with Queue logic

Basic settings

Process - selection of process with Queue logic from "catalog", by its name or its ID.

Node - selection of node with Queue from dropdown list of nodes of previously selected process.

Take From The Begin Of The Queue receive task from queue starting with the first (the oldest)

Take From The End Of The Queue - receive tasks from queue starting with the first (the most "fresh")

In Process and Node it is possible to use dynamic values of task parameters. For example: - process ID, - node ID.


Alert when there is tasks queue

Detailed description of logic work.

Limit the time of the task in the node

Time interval value at which task will go further through process in case if Get from Queue logic does not reply.


When errors appears, process sends task ti the node with Condition logic

and adds some parameters to the task, appropriate to the error:
