Synchronous and Asynchronous transformation in ssis
Synchronous transformation process the incoming rows and pass it to the output one at a time.Output is synchronized with the input. it does not create a separate buffer for output. same buffer is used both for input and output rows. All the non-blocking transformations are synchronous transformation.
An Asynchronous transformation store the input data into the buffer and perform some operations before releasing it to the output buffer. There is two different buffer create for both input and output.Semi-Blocking and Full-Blocking transformations are asynchronous transformation.
