Question about Materializing assets from External Systems: End goal is for people to programmatically run Jobs that can materialize assets via GraphQL APIs Is it possible selectively materialize Assets by invoking a Job with Parameters and each parameter could be an Asset name ? Is it possible to programmatically trigger asset materialization from within a Job ?

Just throwing ideas out there, but maybe you could do this with asset jobs and op-selection when executing the job?

The assets need to be selected GraphQL API call.. since its an external system so it can only interact with Dagster via GraphQL

Yup I understand that part - the

launchPipelineExecution

GraphQL endpoint you'd be using to submit a run has a

stepKeys

argument that seems like you might be able to use to indicate what assets in a job you want to run

Oh, thanks for that. I will just try it out right now
