The Fast Load format cannot be used if there is?

The Fast Load format is specifically designed for efficient data ingestion into the AVEVA Historian Server. This method streamlines the process when data is fed in, but it has a critical restriction when it comes to existing data. If there is already existing stored data for the same time period, the Fast Load format cannot be utilized.

This limitation is significant because the Fast Load process assumes that the data being imported is unique and doesn’t overlap with previously stored records for the same timeframe. If there is a conflict—meaning that the Fast Load would attempt to insert data that has already been recorded in that period—it could lead to inconsistencies or overwriting of critical data. Therefore, ensuring that the time period is free of existing data is essential for a successful Fast Load operation.

Other options do not present similar restrictions:

• When there is no existing data for the same time period, Fast Load can proceed without issues.

• Active connections to the server do not hinder the Fast Load process, as the operation can function with concurrent users accessing the system.

• Datasets exceeding 1GB might have performance considerations, but they do not inherently block the usage of Fast Load formats.

Understanding these concepts surrounding data ingestion methods and their limitations is crucial when working with AVE
