Re: Does the CakePHP ready for 'Large Scale' web applications?

But in this case you have 2 database. One is 'master' and another one is 'default'. So when you are saving data to 'master' and updating data by 'default' or deleting data by 'default'. Then how this 2 database will be synchronized. Data can be lost or any damage? Can you tell me the complete flow of this strategy?

Cleaner solution for master/slave using callbacks (or Behavior)

function beforeSave() {

function beforeDelete() {

function afterDelete() {
