.NET Bulk Operations Overview

What's Bulk Operations library?

Like SqlBulkCopy, it allows you to perform very fast insertion in an SQL Server.

Unlike SqlBulkCopy, it supports all kind of operations:

  • Bulk Insert
  • Bulk Update
  • Bulk Delete
  • Bulk Merge
  • Bulk SaveChanges
  • Bulk Synchronize

And many providers:

  • SQL Server 2008+
  • SQL Azure
  • SQL Compact
  • Oracle
  • MySQL
  • PostgreSQL
  • SQLite

It's easy to use, and easy to customize.

// Easy to use
var bulk = new BulkOperation(connection);

// Easy to customize
var bulk = new BulkOperation<Customer>(connection);
bulk.BatchSize = 1000;
bulk.ColumnInputExpression = c => new { c.Name,  c.FirstName };
bulk.ColumnOutputExpression = c => c.CustomerID;
bulk.ColumnPrimaryKeyExpression = c => c.Code;

Is it that simple?
