Title: METHOD AND DEVICE FOR SHARING CACHE DATA
Abstract:
The objective of the present application is to provide a method and device for sharing cache data. The method specifically comprises: acquiring a data access request about a data file sent by an agented process at a cache agent node end, and sending the data file to the agented process according to the data access request; and managing one or more processes on a computing node by means of the cache agent node, wherein all these data files needing to be used by the agented process are saved in a cache of the cache agent node. Therefore, there is no need for a process on a computing node to maintain an independent cache space thereof, and for a certain specific data file in a cache of a cache agent node, a plurality of processes can be shared, thereby saving cache and computing resources; and meanwhile, there is no need for an agented process to directly establish a connection to a server, and for a plurality of processes managed by the same cache agent node, only one connection to the server needs to be established, thereby reducing a large number of connections to the server caused by subscription behaviours and reducing the load of the server.
