Ssis-913 -

jane.doe@techuniv.edu Abstract SQL Server Integration Services (SSIS) is the de‑facto ETL platform for Microsoft‑based data warehouses. With the release of SQL Server 2022, Microsoft introduced SSIS‑913 , a new engine‑level feature called Dynamic Partition Pruning (DPP) . SSIS‑913 enables runtime‑aware partition elimination during data flow execution, reducing I/O, CPU, and network traffic for large‑scale fact tables. This paper presents a systematic evaluation of SSIS‑913, covering its architecture, configuration, performance impact, and best‑practice guidelines. Using a combination of micro‑benchmarks and a production‑scale star schema (≈ 2 TB), we demonstrate average query‑time reductions of 38 % and peak memory savings of 27 % when DPP is enabled. We also discuss limitations, compatibility considerations, and future research directions for adaptive ETL pipelines. 1. Introduction Modern analytical workloads increasingly rely on partitioned tables to manage petabyte‑scale fact data. Traditional SSIS data flows, however, treat source queries as black boxes and materialize full result sets before any downstream transformation, which can lead to unnecessary scanning of irrelevant partitions.

| Component | Responsibility | |-----------|----------------| | | Queries the system catalog ( sys.partitions , sys.partition_range_values ) to retrieve partition boundaries and stores them in a shared cache. | | Pruning Decision Engine (PDE) | Evaluates downstream predicates (extracted from the data flow metadata graph) against the cached boundaries and generates a pruned source query . | SSIS-913
