[0003] However, when the node is restarted, if the cache is not stored persistently, the cache will be lost, and the loss of the cache will cause the system to run slower for a period of time, bringing a bad experience to the user
Therefore, in the prior art, in order to avoid cache loss, the cached data is generally stored persistently. However, when the amount of cached data is large, the persistent storage of the cached data will not only take a lot of time, but also take up a lot of time. system disk resources

Abstract

The invention discloses a processing method and apparatus for node cache data in a distributed system. The method comprises: reading at least one cache datum of a node, wherein each cache datum is in the form of a data key value pair; for each cache datum, extracting a corresponding data key and performing persistent storage on the data key; and when the node is restarted, loading the data key into a cache of the node. According to the scheme, the time for performing the persistent storage on the cache data is greatly shortened, the occupation of system disk resources is reduced, and the loading speed is increased.

Description

technical field [0001] The invention relates to the technical field of the Internet, in particular to a method and device for processing node buffer data in a distributed system. Background technique [0002] The cache is a buffer for data exchange. When the system needs to read a piece of data in the database, it will first look up the piece of data from the cache. If the piece of data is found in the cache, it will be executed directly. If it is not found in the cache If you find this piece of data, then look it up from the database. Since the operation speed with the help of the cache is much faster than searching from the database, the cache can help the system run quickly and reduce the delay of the system. [0003] However, when the node is restarted, if the cache is not stored persistently, the cache will be lost, and the loss of the cache will cause the system to run slower for a period of time, bringing a bad experience to the user. Therefore, in the prior art, in...
