Is there a way to limit workflow concurrency to 1? In other words, how to prevent a workflow from starting if another instance of the same workflow is already running.

Does this help? https://docs.flyte.org/en/latest/user_guide/development_lifecycle/cache_serializing.html

if not, mind writing up your use-case on this pr: https://github.com/flyteorg/flyte/pull/5659

@alert-oil-1341 thanks for the pointer. I really want to prevent starting any other workflows if one is already active.
