Data stream management method and device

Abstract

A method for managing a data stream includes obtaining attribute information of a currently opened file; and distributing the file to a data stream according to current state information of a plurality of data streams and attribute information of the file.

What is claimed is: 
     
         1 . A data stream management method, comprising:
 obtaining attribute information of a file, the file being a currently opened file;   extracting a sub attribute set of the file, wherein the sub attribute set is configured to reflect at least one of an access mode or a data lifetime of the file; and   distributing, in response to the file being opened, the file to a first data stream among a plurality of data streams in response to the attribute information of the file including the sub attribute set of the file and a current state information of the first data stream satisfying a first preset condition based on a set of current state information of the plurality of data streams and the attribute information of the file including the sub attribute set of the file.   
     
     
         2 . The data stream management method of  claim 1 , wherein the set of current state information of the plurality of data streams includes at least one of:
 a type of files which are currently distributed to each data stream of the plurality of data streams;   a number of the files which are currently distributed to each data stream of the plurality of data streams; or   a total number of times that the files currently distributed to each data stream of the plurality of data streams are modified.   
     
     
         3 . The data stream management method of  claim 2 , wherein the attribute information of the file includes a type of the file, and
 wherein the first preset condition includes the type of the file being the same as the type of the files currently distributed to the first data stream.   
     
     
         4 . The data stream management method of  claim 2 , wherein the current state information of the first data stream further includes at least one of:
 the number of the files currently distributed to the first data stream; or   the total number of times the files currently distributed to the first data stream are modified.   
     
     
         5 . The data stream management method of  claim 4 , wherein the first preset condition based on a set of current state information of the plurality of data streams and the attribute information of the file including the sub attribute set of the file further includes at least one of:
 the number of the files currently distributed to the first data stream being the least among the plurality of data streams; or   the number of times the files currently distributed to the first data stream are modified being the least among the plurality of data streams.   
     
     
         6 . The data stream management method of  claim 1 , the data stream management method further comprising:
 distributing, in response to the file being in an opening state, the file to a second data stream among the plurality of data streams in response to a current state information of the second data stream satisfying a second preset condition according to the set of current state information of the plurality of data streams and the attribute information of the file acquired up to current moment, at a preset time interval.   
     
     
         7 . The data stream management method of  claim 6 , wherein the distributing the file to the second data stream according to the set of current state information of the plurality of data streams and the attribute information of the file acquired up to the current moment, comprises:
 extracting the sub attribute set of the file in the obtained attribute information of the file; and   distributing the file to the second data stream that satisfies the second preset condition according to the set of current state information of the plurality of data streams and the sub attribute set of the file.   
     
     
         8 . The data stream management method of  claim 6 , wherein the set of current state information of the plurality of data streams and the attribute information of the file acquired up to current moment, at a preset time interval, further includes at least one of:
 an average open duration of all files currently distributed to each data stream of the plurality of data streams; or   a total opening duration of all files currently distributed to each data stream of the plurality of data streams.   
     
     
         9 . The data stream management method of  claim 8 , wherein the second preset condition further includes at least one of the following conditions:
 the average open duration of all files currently distributed to the second data stream being the shortest among the plurality of data streams; or   the total opening duration of all files currently distributed to the second data stream being the shortest among the plurality of data streams.   
     
     
         10 . The data stream management method of  claim 6 , wherein, the plurality of data streams comprise a first group of data streams and a second group of data streams; and
 the data stream management method further comprises:   distributing the file to one data stream among the first group of data streams in response to distributing the file based on the set of current state information of the data streams and a type of the file; and   distributing the file to one data stream in the second group of data streams in response to distributing the file according to the set of current state information of the data stream and the attribute information of the file acquired up to the current moment, at a preset time interval.
