How does delta retrieval benefit data management in AVEVA Historian?

Delta retrieval is a method that significantly enhances data management efficiency in AVEVA Historian by focusing on the changes in data over time rather than retrieving all data, which includes unchanged records. By only fetching modifications or updates, this approach minimizes the amount of data traffic generated during the retrieval process. This not only speeds up data access but also reduces the load on network resources, making it more efficient and cost-effective, especially when dealing with large datasets commonly managed in industrial environments.

In environments where data is continuously generated, such as in industrial monitoring systems, retrieving all historical data can lead to unnecessary overhead, consuming time and bandwidth. Therefore, delta retrieval improves performance by allowing users to work with the most relevant data, streamlining operations and enhancing the overall experience of data handling within the AVEVA Historian framework.
