run_spawn(Info, F)

View Source 
-spec run_spawn(log_info(), task_fun()) -> task_result().

Spawns a new process to do some memory-intensive task.

This allows to reduce GC on the parent process. Waits for function to finish. Handles errors. Returns result from the function or crashes (i.e. forwards an error).

run_tracked(Info, Fun)

View Source 
-spec run_tracked(log_info(), task_fun()) -> task_result().

Runs function Fun.

Logs errors. Logs if function execution takes too long. Does not catches the errors - the caller would have to catch if they want to prevent an error.
