The CSV file for import has multiple size and data restrictions. Which of the following is not a restriction?

• A. Data must be in sequential order
• B. Data must not exceed 65,536 rows
• C. Data types must match the schema in the Historian
• D. Data must include a header row

Answer: (A)

The correct answer is that data must be in sequential order is not a restriction for importing a CSV file into the AVEVA Historian. The Historian system allows for data to be uploaded in any order without affecting the integrity of the import process. This flexibility is crucial when dealing with large datasets or when data is available at different times. It enables users to aggregate and import historical data without the requirement to reorganize it sequentially. In contrast, the other options represent established restrictions. For instance, the limit of 65,536 rows is a tangible constraint that users must acknowledge when preparing their CSV files for import. This limitation often arises from underlying system specifications or legacy components that the Historian interacts with. Ensuring that data types align with the schema is also a critical requirement. Matching data types guarantees that the Historian can properly interpret and store the incoming data without errors. Lastly, including a header row is important as it defines the structure of the data being imported. This header row helps the Historian understand the context of each data field, facilitating correct data mapping during the import process.
