Hello 👋 is there a way to avoid starting a new scheduled workflow if the previous one is still running?

Hi @Paul Dittamo, currently there is no support to serialize a workflow execution. There are a number of issues (e.x., 267 , 420 ) that deal with this. We have had some preliminary discussions about how this might be done, but haven't finalized a spec / implementation and scheduled the work to be done. If you have ideas and / or are interested in contributing, we are very happy to collaborate on this. It is certainly functionality that many users are interested in.
I should note that we have implemented similar (but not exact) functionality exists for cachable tasks (issue 872 ). The cache_serializable API (rfc ) is in the final throes of testing, but should be available in the next release.
