In this example, `OtherMongoDbContext` implements `IBookStoreMongoDbContext`. This feature allows you to have multiple MongoDbContext (one per module) on development, but single MongoDbContext (implements all interfaces of all MongoDbContexts) on runtime.
### Customize Bulk Operations
If you have better logic or using an external library for bulk operations, you can override the logic via implementing `IMongoDbBulkOperationProvider`.
- You may use example template below:
```csharp
public class MyCustomMongoDbBulkOperationProvider : IMongoDbBulkOperationProvider, ITransientDependency
{
public async Task DeleteManyAsync<TEntity>(IMongoDbRepository<TEntity> repository,
IEnumerable<TEntity> entities,
bool autoSave,
CancellationToken cancellationToken)
where TEntity : class, IEntity
{
// Your logic here.
}
public async Task InsertManyAsync<TEntity>(IMongoDbRepository<TEntity> repository,
IEnumerable<TEntity> entities,
bool autoSave,
CancellationToken cancellationToken)
where TEntity : class, IEntity
{
// Your logic here.
}
public async Task UpdateManyAsync<TEntity>(IMongoDbRepository<TEntity> repository,
@ -88,87 +88,10 @@ If your entity is a soft-delete entity, you can use the `HardDeleteAsync` method
See the [Data Filtering](Data-Filtering.md) documentation for more about soft-delete.
## Bulk Operations
You can execute bulk operations with `InsertMany`, `UpdateMany`, `DeleteMany` methods.
Both providers `MongoDb` and `Ef Core` support bulk operations.
### Customization
If you have better logic or using an external library for bulk operations, you can override the logic via implementing `IMongoDbBulkOperationProvider` for MongoDb and `IEfCoreBulkOperationProvider` for Ef Core.
- MongoDb Customization:
```csharp
public class MyCustomMongoDbBulkOperationProvider : IMongoDbBulkOperationProvider, ITransientDependency
{
public async Task DeleteManyAsync<TEntity>(IMongoDbRepository<TEntity> repository,
IEnumerable<TEntity> entities,
bool autoSave,
CancellationToken cancellationToken)
where TEntity : class, IEntity
{
// Your logic here.
}
public async Task InsertManyAsync<TEntity>(IMongoDbRepository<TEntity> repository,
IEnumerable<TEntity> entities,
bool autoSave,
CancellationToken cancellationToken)
where TEntity : class, IEntity
{
// Your logic here.
}
public async Task UpdateManyAsync<TEntity>(IMongoDbRepository<TEntity> repository,
IEnumerable<TEntity> entities,
bool autoSave,
CancellationToken cancellationToken)
where TEntity : class, IEntity
{
// Your logic here.
}
}
```
- Entitiy Framework Core Customization
```csharp
public class MyCustomEfCoreBulkOperationProvider : IEfCoreBulkOperationProvider, ITransientDependency
{
public async Task DeleteManyAsync<TDbContext,TEntity>(IEfCoreRepository<TEntity> repository,
IEnumerable<TEntity> entities,
bool autoSave,
CancellationToken cancellationToken)
where TDbContext : IEfCoreDbContext
where TEntity : class, IEntity
{
// Your logic here.
}
public async Task InsertManyAsync<TDbContext,TEntity>(IEfCoreRepository<TEntity> repository,
IEnumerable<TEntity> entities,
bool autoSave,
CancellationToken cancellationToken)
where TDbContext : IEfCoreDbContext
where TEntity : class, IEntity
{
// Your logic here.
}
public async Task UpdateManyAsync<TDbContext,TEntity>(IEfCoreRepository<TEntity> repository,
IEnumerable<TEntity> entities,
bool autoSave,
CancellationToken cancellationToken)
where TDbContext : IEfCoreDbContext
where TEntity : class, IEntity
{
// Your logic here.
}
}
```
You can execute bulk operations with `InsertManyAsync`, `UpdateManyAsync`, `DeleteManyAsync` methods.
> **WARNING:** ConcurrencyStamp can't be checked at bulk operations!
## Custom Repositories
Default generic repositories will be sufficient for most cases. However, you may need to create a custom repository class for your entity.
