LinqToSql Plus Bulk SaveChanges
BulkSaveChanges method is the upgraded version of
All changes made in the context are persisted in the database but way faster by reducing the number of database round-trip required!
BulkSaveChanges supports everything:
- Association (One to One, One to Many, Many to Many, etc.)
- Complex Type
- Inheritance (TPC, TPH, TPT)
- Navigation Property
include template-example.html title='BulkSaveChanges Examples' %}
context.Customers.AddRange(listToAdd); // add context.Customers.RemoveRange(listToRemove); // remove listToModify.ForEach(x => x.DateModified = DateTime.Now); // modify // Easy to use context.BulkSaveChanges(); // Easy to customize context.BulkSaveChanges(bulk => bulk.BatchSize = 100);
ChangeTracker to detect and persist change automatically is great! However, it leads very fast to some problem when multiples entities need to be saved.
SaveChanges method makes a database round-trip for every change. So if you need to insert 10000 entities, then 10000 database round-trip will be performed which is INSANELY slow.
BulkSaveChanges works exactly like
SaveChanges but reduces the number of database round-trips required to greatly help to improve the performance.
|Operations||1,000 Entities||2,000 Entities||5,000 Entities|
|SaveChanges||1,000 ms||2,000 ms||5,000 ms|
|BulkSaveChanges||90 ms||150 ms||350 ms|
