Layer 1 (L1) transformation tasks normalize raw collected data from individual sources into a shared unified schema. The Deduplicator connector reads from these normalized L1 tables to perform its cross-source matching and merging.

 

All L1 tasks are located in the 1.1 Transform Data Collection to Unified Schema task group within the task library. They are organized into source-specific subfolders.

 

Task Execution Order

L1 tasks must be executed in a specific order to produce correct results:

 

1.Source-specific tasks (in their respective source folders) — Run first. These tasks transform raw data from each individual source connector into the unified L1 schema. All source-specific tasks within the subfolders must complete before the Combine tasks are run.

2.Combine tasks (in the numbered order shown in the task group) — Run after all source-specific tasks are complete. These tasks merge the individual source outputs into the final L1 result tables consumed by the Deduplicator. The Combine tasks must be executed in the numbered sequence shown in the task group, as each step may depend on the output of the previous one.

 

When scheduling the L1 pipeline, configure the source-specific tasks to complete before the Combine tasks begin. Use task dependencies or separate task groups with appropriate sequencing to enforce this order.

 

L1 Output Tables

After all L1 tasks have run successfully, the following result tables are available in the results database for the Deduplicator to read from:
