This is subject to the RDBMS having the capacity available to perform these operations, but assuming it does, then this is a useful option to have to hand […] “Leveraging the Database Engine” |

SSIS Unit TestingTesting of SSIS packages can be an ah-hoc, manual process that’s performed only at the package level. I.e. checking that running a whole package (or set of packages) produces the expected data. This approach will likely not test all paths through an ETL, as well as failing to thoroughly test priority fixes […] “SSIS Unit Testing” |
Data Flow ThreadingSSIS provides for parallelism at multiple levels: (i) by running packages concurrently, (ii) by running tasks concurrently within a package, and (iii) by running transformations concurrently within a data flow. This post investigates parallelism within the data flow, by comparing the time taken between non-parallel and […] “Data Flow Threading” |
