Global sequential order of workflow executions with the same workflow id

Hi,

I have a use case where workflows are started when certain database entries are modified. A unique database entry name is used as a workflow id. These workflows can take a while and new modifications might occur during that time. It is important that the corresponding workflows execute in sequential order. Is there a way to achieve this without resorting to an additional work queue that’s outside of Temporal?

Thanks in advance.

The standard approach is to not start a workflow on each modification but SignalWithStart a workflow with the same entry name about it. This way the workflow can buffer the signals and process them one by one.

Great! I am still kind of new to Temporal and haven’t realized that signals could be used in this way. I think this would definitely do the trick.

Thanks
