High performance insert data into database

Dommel.Bulk provides a convenient API for bulk insert operations using extension methods on the IDbConnection interface. The SQL queries are generated based on your POCO entities. Dommel.Bulk translates you entities to SQL expressions. Dapper is used for query execution and object mapping. Dommel is used for table and column names conventions

Installing Dommel

Dommel.Bulk is available on NuGet.

Install using the .NET CLI:

dotnet add package Dommel.Bulk

Install using the NuGet Package Manager:

Install-Package Dommel.Bulk

Using Dommel.Bulk

Bulk insert using type mappers

var products = await connection.BulkInsertAsync<Product>(products);

Generate simple SQL expression using database specific type mappers. Supports MySql database. Has high performance.

Bulk insert using SQL parameters

int insertedCount = await connection.BulkInsertParametersAsync<Product>(products);

Use SQL parameters for insert values. Support for all databases. Has middle performance.

Type mappers

Support CLR types: bool, byte, char, double, float, int, long, sbyte, short, uint, ulong, ushort, decimal, DateTime, DateTimeOffset, Guid, string, TimeSpan, DateOnly, TimeOnly, ArraySegment<byte>, byte[], enum types and nullable types

Async and non-async

All Dommel.Bulk methods have async and non-async variants, such as as BulkInsert & BulkInsertAsync, BulkInsertParameters & BulkInsertParametersAsync.



Implement this interface if you want to customize the mapping types to SQL query

public class JsonTypeMapper : ITypeMapper
    public LambdaExpression GetExpression()
        // Map JSON type to SQL string.
        return (Expression<Func<JObject, string>>)x => $"'{x.ToString().Escape()}'";

Use the AddTypeMapper() method to register the custom implementation:

AddTypeMapper(typeof(JObject), new JsonTypeMapper());


AddTypeMapper(typeof(JObject), new GenericTypeMapper<JObject>(x => $"'{x.ToString().Escape()}'"));
