Is it possible to have many pipelines for 1 runspace.

Question

Hi,

This is executing scripts asynchronously from c# and having threads doing the work of loading the script for execution and waiting for output to come out. I may need to have many scripts executing at once, maybe concurrently.

Is possible to have a 1:M relationship between runspace and pipelines in windows poweshell and if so what are the implications for it. Specifically as regards memory use, if anybody has any experience of this.

Also if their is a way to have more than 1 pipelines per runspace, then would that have a knock on effect from the host.

Answer 1

If you mean multiple simultaneous pipelines in a single runspace: no.

In fact, the one documented exception that the CreatePipeline methods throw is InvalidRunspaceStateException which happens when "the runspace is not in a state that allows a pipeline to be created" i.e. when the previous pipeline hasn't completed yet.
