SQL Server Integration Services ( SSIS ) Transformation and Execution Tree


SSIS Transformation and Execution Tree


There are two main concepts related to SSIS internals which need to be understood before we deep dive in optimizing SSIS packages.
Transformation - There are different kinds of tranformation in SSIS which overall impacts the performance of SSIS.
Execution Tree - At run time, the data flow engine breaks down Data Flow task operations into execution trees. Execution trees are enormously valuable in understanding buffer usage.


I have written an article covering different kinds of transformation and how data flow task operations are divided into execution trees.
