      Work Description: Hannah-Jiang commented on pull request #10536: [BEAM-7861] Add direct_running_mode option for direct runners to switch between multi_threading and multi_processing easily
URL: https://github.com/apache/beam/pull/10536
 
 
   This PR introduces a new direct option --direct_running_mode to make it easy to switch between multi_threading and multi_processing mode for FnApiRunner.
   
   When direct_running_mode is not set, EmbeddedWorkerHandler is used. (This is default mode)
   When direct_running_mode = 'multi_threading', EmbeddedGrpcWorkerHandler is used.
   When direct_running_mode = 'multi_processing', SubprocessSdkWorkerHandler is used.

> BEAM-3645 makes it possible to run a map task parallel.
> However, users need to change runner when switch between multithreading and multiprocessing mode.
> We want to add a flag (ex: --use-multiprocess) to make the switch easy without changing the runner each time.
