read and write lua_shared_dict concurrently

read and write lua_shared_dict concurrently in multi worker, is there any worse problems than getting dirty data?

biello hello, could you talk more about dirty data, I think you can use expire to delete dirty data auto?

I think the biggest problem in lua_shared_dict maybe is the lock for difference worker, if you don't need to exchange data between each worker, lua_shared_dict maybe is too expansive.

tanjinhua in my case, when I update a batch of data in a for loop while other processes is reading that data, it may get some date updated and some not which considered "dirty", however this is acceptable to me.
Thanks for the performance point of view, I will reconsider it.
