What's Entity Framework Extensions?

Entity Framework Extensions is a library that dramatically improves EF performances by using bulk and batch operations.

People using this library often report performance enhancement by 50x times and more!

Improve Entity Framework performance with Bulk SaveChanges and Bulk Operations

Solve Entity Framework performance issue when saving with high performance bulk operations and hundreds of flexibles feature.

• BulkSaveChanges
• BulkInsert
• BulkUpdate
• BulkDelete
• BulkMerge
• DeleteFromQuery
• UpdateFromQuery

var context = new CustomerContext();
// ... context code ...

// Easy to use
context.BulkSaveChanges();

// Easy to customize
context.BulkSaveChanges(operation => operation.BatchSize = 1000);

// Perform specific bulk operations
context.BulkDelete(customers);
context.BulkInsert(customers);
context.BulkUpdate(customers);

// Customize Primary Key
context.BulkMerge(customers, operation => {
   operation.ColumnPrimaryKeyExpression = customer => customer.Code;
});

BulkSaveChanges

Problem

You need to save hundreds or thousands of entities, but you are not satisfied with Entity Framework performance.

Solution

BulkSaveChanges is exactly like SaveChanges but performs way faster. It’s easy to use, you only need to replace “SaveChanges” by “BulkSaveChanges”, and you are done!

// Upgrade SaveChanges performance with BulkSaveChanges
var context = new CustomerContext();
// ... context code ...

// Easy to use
context.BulkSaveChanges();

// Easy to customize
context.BulkSaveChanges(operation => operation.BatchSize = 1000);

Scalability

BulkSaveChanges is as fast as SaveChanges with one entity and quickly become 10-50x faster with hundreds and thousands of entities.

Bulk Operations

Problem

You need even more performance than BulkSaveChanges, save detached entities or save entities in a specific order.

Solution

Use bulk operations such as bulk insert, update, delete and merge which perform operations on specified entities and bypass the change tracker to increase performance.

// Perform specific bulk operations on entities
context.BulkDelete(customers);
context.BulkInsert(customers);
context.BulkUpdate(customers);
context.BulkMerge(customers);

Maintainability

Bulk Operation uses directly the Entity Framework Model. Even if you change column name or change inheritance (TPC, TPH, TPT), Bulk operation will continue to work as expected.

Custom Key

Problem

You need to perform an update, delete, or merge using a specific custom key like the custom code.

Solution

Specify your own key by customizing the operation.

// Use flexible features such as specifying the primary key
context.BulkMerge(customers, operation => {
   operation.ColumnPrimaryKeyExpression = customer => customer.Code;
});

Flexibility

Bulk operations offer hundreds of customization such as BatchSize, Custom Key, Custom Mapping, etc.
