What's New in Release 4.5


Optimized for the Cloud

Kourier Integrator includes improved functionality, increased performance and guaranteed data processing when integrating with Microsoft SQL Server databases hosted in cloud environments such as Microsoft Azure or Amazon Web Services (AWS). 


  • Microsoft SQL Server 2017 is supported using Kourier's maintenance-free SSIS packages.
  • SSIS packages will re-process files that are not available due to latency in cloud file storage systems.
  • Kourier will auto recover from system file locks caused by virus scans, windows indexing, etc.
  • Automatically detect if an instance of a SSIS package is still running and react appropriately.
  • New configuration options enable Kourier to be tuned for optimum performance in cloud environments.
  • SSIS packages can be configured to not send email notifications.

Improved Performance for ODBC Data Sources

Kourier Integrator is significantly faster when loading Microsoft SQL Server databases from non-U2 data sources via Kourier's ODBC adaptor.


  • Kourier's Net Change engine (aka change data capture) was redesigned for ODBC data sources:
    • Tracking net changes with deletes is more efficient when identifying which records were deleted from the source table.
    • Updating Microsoft SQL Server databases from ODBC data sources is up to two times faster.
  • Improved the workflow when running ODBC export services with related tables (e.g., year-based tables):
    • The user can select a single table or all tables to process.
    • This makes it much easier to aggregate a related table into a single table.

REST Improvements

Key enhancements extend Kourier REST's capability to quickly build REST APIs with enhanced support for JSON (JavaScript Object Notation) plus enhanced Swagger API documentation that is more interactive and comprehensive.


  • Provide more control of the serialized JSON generated output: 
    • Group MultiValue associated fields as either an object or an array of objects.
    • Implemented new formatting directives that require no additional coding.
  • Enhanced support for JSON with inbound REST APIs (POST, PUT, PATCH and DELETE).
  • Inbound REST APIs can process either XML or JSON without changing specification:
    • Simple XPATH expressions provide a consistent structure.
    • API consumers can choose their preferred response format.
  • Declare the default format (XML or JSON) expected to be processed by the inbound REST API.
  • API developers can control the HTTP status code returned to the API consumer.
  • Improved error handling for REST Subscriptions using Kourier's Event Notification system.

Swagger Documentation

  • Swagger output is more interactive and usable by API consumer.
  • Includes the response payload definition if a response export was specified.
  • Request and response payload formats now show the hierarchical structure.
  • Includes the "produces" property for each GET operation.
  • Includes the "consumes" property on each POST/PUT operation.

Other Updates and Improvements

This release of Kourier Integrator includes many other improvements and smaller enhancements as described below.
