SSIS: Script Component Asynchronous Transformation

We can configure the SSIS Script component output as a Synchronous or Asynchronous as required. Using the Synchronous setting each input row is processed as it passes through the component, where as Asynchronous setting waits until multiple input rows have been received before processing.

I had to use this when I was integrating two system using SSIS package. The scenario was to send the massive amount of data in a chunk from the source system into the other system in the JSON format. This Asynchronous setting helped to send the data in a limited batch size.

In order to configure in Asynchronous setting, we need to configure Output 0 to be an asynchronous output. Click on Output 0 in the Inputs and outputs and set the Synchronous property to None.
