Question

Hi here the tasks on Left branch are running fine but the tasks on the Right Branch are stuck in Mapped state Both have the same functions called and mapped to run a task

Kevin Kho · Answer

Are you using LocalDaskExecutor

Muddassir Shaikh · Answer

Yes LocalDaskExecutor

Kevin Kho · Answer

Are you using threads or processes Processes might help it become more stable

Muddassir Shaikh · Answer

```left branch = processing map processing channels some var1 date right branch = processing map processing channels some var2 date ```

Kevin Kho · Answer

No no I mean `LocalDaskExecutor scheduler= processes `

Muddassir Shaikh · Answer

`flow executor = LocalDaskExecutor `

Kevin Kho · Answer

Yes the default is `threads` `processes` is more stable You can see the syntax <https docs prefect io orchestration flow config executors html localdaskexecutor|here>

Muddassir Shaikh · Answer

Thanks

Muddassir Shaikh · Answer

Also is there any maximum limit for parallel processing

Kevin Kho · Answer

Not on the Prefect side It would be your hardware limits

Muddassir Shaikh · Answer

Cool

Muddassir Shaikh · Answer

Hi < Kevin Kho> i am still facing the Mapped state issue even after adding processes in LocalDaskExecutor

Kevin Kho · Answer

Does it not run after the left side finishes running Prefect currently only runs one mapped task at a time

Muddassir Shaikh · Answer

Yes but the left side takes several hours to finish I want to run both mapped task to run in parallel as they are not interdependent

Kevin Kho · Answer

Ah I see now The FlowRunner currently only runs one mapped task at a time

Muddassir Shaikh · Answer

Ohh okay let me know if you find any fix Thanks
