c# - How can a parent actor track status of a sub tasks performed by child actors -

i have actor system parses large data, way implemented parent actor divide task multiple child actors run in parallel. part works fine. question how can parent actor status of each child knows sub tasks completed?

make child actors tell parent actor when finished, tell updates etc.

edit: if want results of aggregate of responses ... use actor aggregate responses? alternatively use count. answer valid , correct if apply 20 seconds of thought. if want child actor provide update parent of progress - no matter complexity of solution - have tell parent progress. if want insert actors middle or use count in parent actor figure out how far through complete process answer still tell parent upon completion.

you answers ask. if ask wrong question because answers don't answer question wanted doesn't mean wrong (especially given still right answer)

people answering questions on here not required - nor should expected - read comments on question - asker required update question. not being funny, busy , shouldn't making me work you.

this question should closed duplicate / vague / incorrect. when responses legitimately answering questions makes aggression of answerers towards askers feel justified.
