The default downsampling method to use when this signal is re-sampled into larger intervals. When two or more values in an interval needs to be aggregated into a single value, specifies how they are combined.

• AGGREGATION_INVALID: Aggregation is unspecified and invalid. Aggregation must be set.
• MEAN: Takes the arithmetic mean of the data values. Example: 2, 1, 3, 5, 4 -> 3.
• FIRST: Selects the first value. Example: 2, 1, 3, 5, 4 -> 2.
• LAST: Selects the last value. Example: 2, 1, 3, 5, 4 -> 4.
• SUM: Sums the data values. Example: 2, 1, 3, 5, 4 -> 15.
• MIN: Selects the minimum value. Example: 2, 1, 3, 5, 4 -> 1.
• MAX: Selects the maximum value. Example: 2, 1, 3, 5, 4 -> 5.
• MEDIAN: Selects the median value. Example: 2, 1, 3, 5, 1000 -> 3.
