In this article, we explored eager and lazy loading in detail, covering their benefits and differences. We also implemented both lazy and eager loading in a single-page application like React using only components. These techniques are essential in optimizing the performance of web applications. La...
In software development, efficient data retrieval is a critical aspect of creating high-performance applications. When working with databases, developers often face choices between loading strategies, two of the most common being eager loading and lazy loading. In the context of .NET Core, understandi...
ActiveRecord默认是lazy loading的,而加上:include选项后可以指定eager loading一些字段 :include - specify second-order associations that should be eager loaded when the collection is loaded. 看例子: Post.find(:all, :include => :comments) # => SELECT ... FROM posts LEFT OUTER JOIN comments ON ....
These strategies, namely Lazy Loading and Eager Loading control how data is fetched from the database. We will also delve into performance impacts and considerations for choosing one over the other. To download the source code for this article, you can visit our GitHub repository. Let’s begin...
Now, in this article, we will go one step further and discuss when a LINQ query gets executed. LINQ query is not executed when constructed but when enumerated. There are two types of query executions in LINQ, which are given below. Deferred or Lazy Loading Eager Loading....
your entity mapping. It specifies when your JPA implementation, e.g., Hibernate, fetches associated entities from the database. You can choose betweenEAGERandLAZYloading. The first one fetches an association immediately, and the other only when you use it. I explain both options in this ...
Eager loadingmeans that the related data is loaded from the database as part of the initial query. Explicit loadingmeans that the related data is explicitly loaded from the database at a later time. Lazy loadingmeans that the related data is transparently loaded from the database when the nav...
