1. a hash data processing method, it is characterised in that including:

  • Receiving data processing instructions in data processing, described data processing instructions includes being inserted intoKey value, this data handling procedure includes that encoding and decoding processing procedure, data compression process process or data addClose processing procedure;

    The hash function using hash function to concentrate generates first pressure corresponding with the key value being inserted intoContracting key value, described hash function is concentrated and is included at least two hash function;

    If Hash bucket exists described first compression key value, then use that described hash function concentrates anotherHash function generates the second compression key value corresponding with described key value;

    Another hash function described be withThe hash function that the position of the empty list item in Hash bucket is corresponding, the hash function that described hash function is concentrated withList item position in described Hash bucket has binding relationship;

    Described second compression key value is stored in sky list item, and enters according to described second compression key valueRow data process.
