Aggregate data by time
You can downsample and upsample persisted data using the
Aggregating and interpolating
The JSON payload can include a
groupByTime property, an object with the following members:
timeBucketDuration- The duration, in nanoseconds, for one aggregated value.
interpolationType- Specify how additional values should be generated when interpolating.
For example, imagine you have a set of speed data, with values recorded at 1-second intervals. You can group such data into 2-second intervals, aggregated by mean average, with the following:
You can specify an
interpolationType to define how any missing values are generated.
Linear will provide a value in linear proportion, while
Previous will repeat the value before the one that was missing:
