1. A computer-implemented method comprising: an engine receiving time series data; the engine referencing a first input to create from the time series data, a first representation comprising a covered time period, a compression model, an error bound, and a storage medium, wherein the configuration designates the first representation as lying within a hot zone; the engine storing the first representation within the storage medium; the engine referencing a second input to create from the time series data, a second representation differing from the first representation in at least one of the covered time period, the compression model, the error bound, and the storage medium; and the engine storing the second representation.
