When does Relativity begin processing a second data source in a single processing set?

In the context of Relativity processing, the correct sequence for beginning the processing of a second data source within a single processing set occurs after Deduplication Document ID Creation. This step is essential because it ensures that all documents from the source being processed are assigned unique identifiers, which are critical for tracking and managing documents through subsequent stages of processing.

When a second data source is introduced, it is important to have a clear and organized way of identifying and referencing each document throughout the workflow. Deduplication, at this stage, helps to eliminate redundant documents and assigns Document IDs, preparing the system for the integration of additional data sources. This systematic approach allows for efficient processing, analysis, and review later on.

Other steps, like de-NIST or Master Document Publish, occur either before or after this stage and do not directly initiate the processing of an additional data source within the same set. Overlaying Deduplication metadata may involve subsequent actions that build upon the foundational work laid out during Deduplication Document ID Creation but is not the stage that triggers the processing of a new source. Thus, understanding the hierarchy and flow of these steps is crucial for effectively managing multiple data sources in Relativity.
