Abstract
Provided are a method and device for storing time series data with adaptive length encoding, including: acquiring data values corresponding to timestamps according to a sequential order of timestamps; using a ratio of storage space values required to pre-store the previous n data values to storage space values required to pre-store rule information of a preset encoding rule and encoding data according to the previous n data values as a storage gain corresponding to the time at which the n-th data value is acquired; storing the rule information of the preset encoding rule and the encoding data corresponding to a previous n−1 data values when the storage gain corresponding to the time at which the n-th data value is acquired is less than that corresponding to the time at which the (n−1)-th data value is acquired.
