Lazy loading is the opposite of loading

The opposite concept of lazy loading is "Eager Loading", which refers to the loading strategy of obtaining all relevant data immediately when the object is initialized or loaded. The advantage is that all data can be loaded in advance to avoid subsequent access times. delay, suitable for scenarios that require frequent access to associated data.

The opposite concept of lazy loading is immediate loading (Eager Loading), which refers to a loading strategy that immediately obtains all relevant data when the object is initialized or loaded.

Unlike lazy loading, immediate loading will obtain all the required data at once when the object is initialized or loaded, regardless of whether the data is actually used. This loading method may lead to data redundancy and performance loss, especially when there are many associated objects or a large amount of data.

The advantage of immediate loading is that all data can be loaded in advance to avoid delays in subsequent access. It is suitable for scenarios that require frequent access to associated data. However, when the amount of data is huge or the associated objects are complex, immediate loading may cause additional overhead and performance issues.

Lazy loading and immediate loading are two different strategies for loading data. Choosing the appropriate loading method according to specific application scenarios and requirements can improve system performance and resource utilization.
