c# - How to update multiple MongoDB servers simultaneously - direct mode or replica set? -



interested in using mongodb cache servers. relatively new mongo bear me ...
1 of tasks should perform following:
retrieve records database , update 2 mongodb servers. task writes mongo servers , doesn't perform "read" actions. task should run every 250 ms , amount of documents updated between 0 - 180 records (relatively small records - each record document).

know how can perform task using one update in code? (i not want loop on servers , perform update each of them)

one point mention: data in mongo servers should read locally @ each machine in order gain small latency possible.

should create replica set? if so, replica set reflect up-to-date data in each server given frequency of 250 ms?

or should connect them directly mongodb://server1,server2/?connect=direct , perform 1 update in code translated 2 updates - 1 each server?

replies inline..

i know how can perform task using 1 update in code? (i not want want loop on servers , perform update each of them)

you can bulk insert or multi update. @ mongod server side, applied in sequence.

should create replica set? if so, replica set reflect up-to-date data in each server given frequency of 250 ms?

you can't sure replicated secondaries in 250 ms. but, default read goes primary ( replica-set ) up-to-date data.

or should connect them directly mongodb://server1,server2/?connect=direct , perform 1 update in code translated 2 updates - 1 each server?

you have connect 'mongodb://server1,server2?..options'. update goes primary, , update pulled secondary primary.

keyboard - C++ GetAsyncKeyState alternative -

i using windows.h library's getasynckeystate function define key pushed on keyboard . here program returns int value of pushed key example. #include <iostream> #include <windows.h> using namespace std; int main (){ char i; for(i=8;i<190;i++){ if(getasynckeystate(i)== -32767){ cout<<int (i)<<endl; } } return 0; } but trying make opengl simple game , function appeared slow . there function not need cycle 180 times , if statement . thanks you're trying make opengl game, you're going use glfw. if that's case can away using glfwgetkey() such: if (glfwgetkey(glfw_key_up) == glfw_press) {...} if (glfwgetkey(glfw_key_down) == glfw_press) {...} that method nicely explained in tutorial 6 opengl-tutorial.org . should start first tutorial of beginners tutorials , later intermediate tutorials . if you're going make win32 window can listen wm_keydown or wm_keyup messages , virtua...
