Hi everyone I am just getting started with Prefect by settin

Question

Hi everyone I am just getting started with Prefect by setting up my server and writing a few workflows locally i get stuck in a situation where i need to trigger a workflow using an API like we do in Python Requests module I have come across a few links where they mention that it is possible using the AWS lambda function So I wanted to know if the Python Requests module can trigger a workflow locally or not I am using prefect 2 7 7 version

Hey < Nimesh Kumar> you can trigger flow runs from the you ll need to have created a that can be accessed from the API this discourse article is also a good place to start with this as well

Nimesh Kumar · Answer

Thank you for the response As per your suggestion I have created a deployment and tried triggering using the below code ```t = await client create flow run from deployment deployment id= a49ac4d8 0855 4000 9cfc c352319eba0c name= TriggeredExternally ``` In the dashboard it is reflecting that the flow is triggered but the state is not changing and shows Late

This is solved Actually there was a problem in Queue

Nimesh Kumar · Answer

DOUBT Hi Let suppose i have created a workflow X and for that i have created a deployment Y with a queue Z I am triggering the workflow deployment using deployment externally after running ```prefect agent start work queue Z ``` So i have doubt that when the deployment is triggered from multiple system it will still use the same queue i e Z Or we can assign the queue while triggering the deployment Or we can create multiple queues initially and if multiple requests come it will automatically get assigned to a queue but then how is the prefect deciding which queue to use

redsquare · Answer

The deployment is assigned to a queue and will always use that queue when triggered

Nimesh Kumar · Answer

So a single deployment cannot have a multiple queues or there is be multiple workers for a queue which I can configure

redsquare · Answer

Typically the queue doesnt do much work just create a job for the flow to run

Nimesh Kumar · Answer

so if I trigger deployment let say 1000 time in 30 sec then queue will be a bottle neck

redsquare · Answer

Too hard to say depends on whats its doing the size of the vm you can have multiple agent processes to be started for a single work queue

Nimesh Kumar · Answer

Can you please provide me any links related to setting up multiple agents for a single work queue I tried searching but couldn t found any

redsquare · Answer

Nimesh Kumar · Answer

Hi I apologize if I am bothering you too much but I did go through the link you provided but I am still confused you are saying that starting multiple agent for a single queue can help but I am not able to figure out how can I start multiple agent ```prefect agent start q my queue ``` This will start one agent and create a new queue Now I need to create a another agent for the same queue i e my queue and this where i got stuck

redsquare · Answer

yeah you can just create another agent listening to the same queue

Nimesh Kumar · Answer

```prefect agent start q my queue prefect agent start q my queue ``` This will create two agents that will point to the same queue my queue right

redsquare · Answer

yeah
