What does Full Retrieval return?

Full Retrieval returns all stored data points, even if values are repeated. This means that if a particular data point has been recorded multiple times during the data logging process, Full Retrieval will include each of those instances in the result set. This is particularly useful in applications where historical context is valued, as it allows for a comprehensive view of the data, including trends, patterns, and anomalies that might not be visible if only unique values were considered.

In contrast, options focusing on unique data points or specified ranges would limit the data to a narrower scope, potentially obscuring important insights that can be gleaned from the full history of data points captured by the system. Similarly, retrieving only the latest data points would not provide a historical perspective, which is essential for trend analysis or understanding changes over time. Thus, Full Retrieval is designed to give a complete dataset as it exists in the historian, making it the ideal choice when comprehensive data analysis is required.
