Query: FlashP: An Analytical Pipeline for Real-time Forecasting of Time-Series
  Relational Data   Interactive response time is important in analytical pipelines for users to
explore a sufficient number of possibilities and make informed business
decisions. We consider a forecasting pipeline with large volumes of
high-dimensional time series data. Real-time forecasting can be conducted in
two steps. First, we specify the part of data to be focused on and the measure
to be predicted by slicing, dicing, and aggregating the data. Second, a
forecasting model is trained on the aggregated results to predict the trend of
the specified measure. While there are a number of forecasting models
available, the first step is the performance bottleneck. A natural idea is to
utilize sampling to obtain approximate aggregations in real time as the input
to train the forecasting model. Our scalable real-time forecasting system
FlashP (Flash Prediction) is built based on this idea, with two major
challenges to be resolved in this paper: first, we need to figure out how
approximate aggregations affect the fitting of forecasting models, and
forecasting results; and second, accordingly, what sampling algorithms we
should use to obtain these approximate aggregations and how large the samples
are. We introduce a new sampling scheme, called GSW sampling, and analyze error
bounds for estimating aggregations using GSW samples. We introduce how to
construct compact GSW samples with the existence of multiple measures to be
analyzed. We conduct experiments to evaluate our solution and compare it with
alternatives on real data.
