Previous versions (≤ 6.x) failed after the first execution unless the app was restarted.
Please upgrade to v7.0.0+ for reliable multi-execution support.

Loki Bulk Data Processor

The Loki Bulk Data Processor is a fast, efficient .NET library for bulk data inserts into SQL Server using SqlBulkCopy. Designed for ASP.NET Core, it supports:

  • IEnumerable<T> models
  • DataTable
  • IDataReader (v6.0.0+)
  • JSON streams (v6.0.0+)
  • Structured logging and mapping support (v6.0.0+)

Perfect for high-throughput ETL pipelines and real-time ingestion scenarios.

Install

  dotnet add package LokiBulkDataProcessor

Performance

Benchmark: 100,000 records inserted into an empty SQL Server table with 4 columns (1 primary key, 1 foreign key), on a 2.7GHz i7, 16 GB RAM, SSD.

Method Time Taken Memory Usage
Loki Bulk Processor 2.99 seconds 266 MB
Entity Framework Core 68.74 seconds 1 GB+

Inserted 100,000 records into an empty table with 1 PK and 1 FK column.

⚠️ Entity Framework was used with AddAsync and SaveChangesAsync. Loki used a single bulk insert call.

Upgrade Guide

⚠️ Critical Bug Fix: LokiBulkDataProcessor is now safe for consecutive executions in ASP.NET Core Web APIs.
 Previously, only the first execution succeeded unless the app was restarted. Thanks to new internal handling, this limitation is resolved.

 🆕 Improvements:
 - SaveAsync methods for IDataReaders and JsonStreams
 - Structured logging for better observability

 🔧 Breaking Change:
 - Renamed DataTableMapping to DataMapping

 This update represents a major reliability milestone. If you rely on Web API scenarios, upgrade as soon as possible.
