# 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
```csharp
var context = new CustomerContext();
// ... context code ...
// Easy to use
context.BulkSaveChanges();
// Easy to customize
context.BulkSaveChanges(operation => operation.BatchSize = 1000);
```
```csharp
// 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;
});
```
##### Scalable
SQL Server - Benchmarks
| Operations | 100 Rows | 1,000 Rows | 10,000 Rows |
| ------------------ | -------: | ---------: | ----------: |
|**BulkSaveChanges** | 20 ms | 200 ms | 2,000 ms |
|**BulkInsert** | 2 ms | 6 ms | 25 ms |
|**BulkUpdate** | 27 ms | 50 ms | 80 ms |
|**BulkDelete** | 25 ms | 45 ms | 70 ms |
|**BulkMerge** | 30 ms | 65 ms | 160 ms |
##### Extensible
Support Multiple SQL Providers:
- SQL Server 2008+

## 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.
```csharp
// Perform specific bulk operations on entities
context.BulkDelete(customers);
context.BulkInsert(customers);
context.BulkUpdate(customers);
context.BulkMerge(customers);
```
##### Maintainability
Bulk Operation directly uses 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.
```csharp
// 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.
