How is deduplication order determined if two data sources have the same order or no order is specified?

When two data sources have the same order or no order is specified, deduplication is typically determined by the Artifact ID. The Artifact ID serves as a unique identifier for each piece of data, ensuring that even if two items are identical in content and arise from different sources, they can be distinguished based on their unique IDs. This is particularly important in a system where data integrity and identification are crucial, allowing for a clear and efficient process in identifying duplicates.

Using Artifact IDs ensures that there is a reliable method to determine which data should be retained and which should be considered a duplicate, thus streamlining the deduplication process. Other factors, while important in different contexts, do not provide the same level of uniqueness or consistency as the Artifact ID, which is why it is the correct choice in this scenario.
