php - message queue - smallest amount of work for a consumer -


this question architecture / design:

i have consumer needs perform x numbers of tasks, when should think breaking consumer smaller task and/or adding smaller tasks own consumer?

example:

consumer foobarshipping does

  • adds database entry reporting
  • adds database entry account
  • adds database entry shipping
  • generates shipping invoice ( pdf or other formats if needed )
  • creates notification shipping
  • creates notification account

so question is, when break out bullet points smaller consumers? consumer runs fine feel it's getting large , needs refactored smaller, more manageable processes.

should each bullet point it's own consumer? can see breaking them 3 consumers

  • database
  • pdf ( documents )
  • notifications

but smallest unit of work consumer should do? need consumer run sql statement?

i watched

and me consumer looks basic tasks kick off other basic tasks.

for general architecture, has 6 modules , each want grouped into:

  • 1 adds database entry reporting
  • 1 adds database entry account
  • 1 adds database entry shipping
  • 2 generates shipping invoice ( pdf or other formats if needed )
  • 3 creates notification shipping
  • 3 creates notification account

if implementing repository pattern, group 1 should separated 3 repositories. each repository handle each entity (reporting, account, shipping); can provide insert, update, delete , select operation.

same group 3, don't think general notification object (class in term) thing because can grow x, y, z entity notification.

but don't worry, @ right path. if talk dependency, constructor injection, separate 3 objects. general idea foobarshipping ship method:

foobarshipping.ship(invoice inv){     invoicerepository.insertnew(inv);     invoicegenerator.generateinvoice(inv);     invoicenotification.notify(inv); }

and general idea invoicerepository.insertnew:

invoicerepository.insertnew(invoice inv){     reportingrepository.insertnew(inv.reporting);     accountrepository.insertnew(inv.account);     shippingrepository.insertnew(inv.shipping); }

same idea invoicenotification.notify:

invoicenotification.notify(invoice inv){     shippingnotification.notify(inv);     accoountnotification.notify(inv); }

it may need adjustment regarding data structure , implementation though. general idea. can refer article (refactoring aggregate services) references though.

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
