* This class provides an easy way for apps to store config values in the
* database .
2024-01-11 17:32:58 +01:00
*
2024-01-15 15:50:44 +01:00
* ** Note :** since 29.0 . 0 , it supports ** lazy loading **

*
2024-01-15 15:50:44 +01:00
* ### What is lazy loading ?
* In order to avoid loading useless config values into memory for each request ,
* only non - lazy values are now loaded .
2024-01-11 17:32:58 +01:00
*
2024-01-15 15:50:44 +01:00
* Once a value that is lazy is requested , all lazy values will be loaded .
2024-01-11 17:32:58 +01:00
*
2024-01-15 15:50:44 +01:00
* Similarly , some methods from this class are marked with a warning about ignoring
* lazy loading . Use them wisely and only on parts of the code that are called
* during specific requests or actions to avoid loading the lazy values all the time .

2024-01-15 15:50:44 +01:00
