A web services platform includes a data collector and a timeseries service. The data collector is configured to collect samples of data points and generate input timeseries including a plurality of the samples. The timeseries service is configured to identify a first timeseries processing workflow that uses the input timeseries as an input and defines processing operations to be applied to the samples of the input timeseries, perform the processing operations defined by the first timeseries processing workflow to generate a first derived timeseries comprising a first set of derived timeseries samples, identify a second timeseries processing workflow that uses the first derived timeseries as an input and defines processing operations to be applied to the samples of the first derived timeseries, and perform the processing operations defined by the second timeseries processing workflow to generate a second derived timeseries comprising a second set of derived timeseries samples.
