Is NHibernate lazy loading?
When loading an order entity from database the default behavior of NHibernate is to lazy load all associated objects of the order entity. This can make our data fetching rather slow and put a (unnecessary) burden onto our database.
When should you not use lazy loading?
When you SHOULDN’T use lazy load:
- You have images above the fold. (it delays your header/banner load)
- You have a store.
- Doing it only to fool pagespeed scores.
- You’ve got a CDN.
- Have only a few images on each page.
- You have a fast-loading website and strong server.
What is the opposite of lazy loading?
The opposite of lazy loading is eager loading.
Which is better lazy loading or eager loading?
With Lazy Loading, we only retrieve just the amount of data, which we need in a single query. If you are not sure of what data is exactly needed, start with Lazy Loading and if it is leading to N + 1 problem then Eager Loading handles the data better.
What is lazy loading in NHibernate?
A more thorough answer: Lazy loading is the default in NHibernate. So if you are not doing anything to circumvent it, you are going to use lazy loading. With lazy loading you can use nested objects (with many relationships to other tables) and it is going to work fine. They are loaded from the database as needed.
What is lazy fetching in Hibernate?
Lazy fetching decides whether to load child objects while loading the Parent Object. You need to do this setting respective hibernate mapping file of the parent class. Lazy = true (means not to load child) By default the lazy loading of the child objects is true.
Should I use Lazyload?
You should always use lazy loading for the images below the fold. As we explained, lazy loading will reduce the real and perceived loading time. User experience will benefit from it — and you users will thank you.
Does lazy loading affect SEO?
Lazy loading images improves the user experience by saving bandwidth for important content first. Some reject the technique for SEO considerations. But properly lazy loading your images does not prevent them from being indexed. Images need to be optimized, adapted to its rendering area, and only loaded if required.
What is lazy loading in Entity Framework?
Lazy loading is the process whereby an entity or collection of entities is automatically loaded from the database the first time that a property referring to the entity/entities is accessed. Lazy loading means delaying the loading of related data, until you specifically request for it.
What is difference between lazy loading and eager loading?
While lazy loading delays the initialization of a resource, eager loading initializes or loads a resource as soon as the code is executed. Eager loading also involves pre-loading related entities referenced by a resource.
What is difference between eager loading vs lazy loading?
Lazy Loading vs. Eager Loading. While lazy loading delays the initialization of a resource, eager loading initializes or loads a resource as soon as the code is executed. Eager loading also involves pre-loading related entities referenced by a resource.
What is the difference between eager and lazy loading in Entity Framework?
Eager loading means that the related data is loaded from the database as part of the initial query. Lazy loading means that the related data is transparently loaded from the database when the navigation property is accessed.
How does hibernate use lazy loading on entities?
Hibernate applies lazy loading approach on entities and associations by providing a proxy implementation of classes. Hibernate intercepts calls to an entity by substituting it with a proxy derived from an entity’s class.
Is the lazy loading mechanism provided by NHibernate?
In this article I want to discuss the lazy loading mechanism provided by NHibernate. It is recommended for maximum flexibility to define all relations in your domain as lazy loadable. This is the default behavior of NHibernate since version 1.2. But this can lead to some undesired effects if querying your data.
What is the difference between Entity Framework and NHibernate?
Entity Framework support any platform because Entity framework runs on .Net core and it is based on a provider model that theoretically can work with any database except relational. NHibernate support .Net 4 and mono which is available in higher running on windows or platform and version 5.1 support .Net core. .
Why is NHibernate loading 2 order lines in one go?
This can make our data fetching rather slow and put a (unnecessary) burden onto our database. This time we have been lucky! NHibernate has automatically generated an optimized query for us and has loaded the 2 order line items in one go.
