User online state quick query method and system

The invention belongs to the technical field of mobile internet, and particularly relates to a user online state quick query method and system. The method comprises the following steps that a management unit receives user state data and performs calculation to obtain a fragment address; a storage unit finds a corresponding fragment storage module according to the fragment address and stores the user state data; an intelligent agent unit initiates a request to the management unit and obtains the fragment address; the intelligent agent unit receives a query request, directly sends the query request to the fragment storage module corresponding to the fragment address, and obtains the user state data fed back by the fragment storage module; and the intelligent unit performs summarization on the user state data to obtain summarized data, and feeds back the summarized data to an online message sending unit. Compared with a conventional database system or cache technology, millions of query requests per second can b
