Hi everyone - I'm currently evaluating using Prefect/Dask for our ETL engine, running through our various use-cases - reading through the open-source docs I'm wondering if there is a simple way to trigger execution of a task from the outside, say, from an AWS lambda function written in Javascript...any ideas?

Also, wondering how much latency would be involved...

Hi @Kenneth Miller ! Yes you can trigger Prefect Flows using the GraphQL API

I can’t speak on exact latency but it’s pretty lightweight. It’s just a matter of hitting the end point.

Copy code

mutation {
  create_flow_run(input: { 
  flow_id: "<flow id>", 
  parameters: "{\"a\":2}" 
  }) {
    id
  }
}

Looks like there is idempotency support too - awesome.
