How does the 'Delta' retrieval method function?

The 'Delta' retrieval method functions by focusing on the differences between values at specific points in time rather than retrieving the full dataset. This is particularly useful in scenarios where only the change in data is of interest, allowing users to analyze trends or shifts in values without processing unnecessary information.

For example, if you are monitoring a temperature sensor, the Delta method would provide the increase or decrease in temperature readings over time, rather than all the individual readings. This can enhance performance by reducing data volume and speeding up retrieval processes, making it easier to identify significant changes or anomalies.

The other methods mentioned serve different purposes; one retrieves all data points, another would focus on maximum values, and another gathers data over specified time intervals, which do not align with the distinct operation of the Delta method.
