""" Gets data from mongoDB, aggregates it, and posts the results back to mongodb. Returns an unique identifier for the timeseries.
The aggregation values are calculated based on the provided weights.
Arguments:
startTime {float} -- Unix time, start of range to query.
endTime {float} -- Unix time, end of range to query.
tag {string} -- The tag of the data. E.g 'bitcoin'
Keyword Arguments:
granularity {int} -- The step size in the time dimension to aggregate on (default: {HOUR})
submissionWeight {int} -- The weight given to the existence of a submission (default: {3})
submissionScoreWeight {int} -- The weight given to the score of a submission (default: {1})
commentWeight {int} -- The weight given to the existence of a comment (default: {2})
commentScoreWeight {int} -- The weight given to the score of a comment (default: {1})
Returns:
string -- uuid used to tag the timeseries. Corresponds to the seriesId field in mongoDB.
