Embodiment Construction

[0066] The technical solutions in the embodiments of the present invention will be described below with reference to the drawings in the embodiments of the present invention.

[0067] In order to solve the problem of untimely index update in the prior art, thereby improving user experience, embodiments of the present invention provide an index update system, method, and device.

[0068] Such as figure 1 As shown, the application scenario of the embodiment of the present invention includes the database server 100, the Kafka server 200 and the client server 300, and the database server 100, the Kafka server 200 and the client server 300 are connected to each other through a network and can communicate with each other.

[0069] Among them, the database server 100 can be a database, which is used to store various data files; the client server 300 is connected with the client terminal to provide corresponding network services for the client terminal, for example, the user watches a...

Abstract

The embodiment of the invention provides a system, method and device for updating the index. The system, method and device for updating the index include the steps of obtaining a target data updating message through a database server according to a target data file where data is updated, and sending the target data updating message to a Kafka server; receiving and storing the target data updating message sent by the database server through the Kafka server; acquiring the target data updating message from the Kafka server through a client server, determining a target index of the target data file according to the target data updating message, and updating the index, in a local-storage index file, of the corresponding target data file according to the target index. According to the technical scheme of the embodiment, a mode of data updating message passing is adopted, so that the client server is enabled to determine the index of the data file where the data is updated and then update the index of the data file; since the time consumption of data updating message passing is short, and it is avoided that the efficiency of data updating message passing is affected due to excessive loading pressure of the database server, index updating can be conducted timely, and then the user experience is improved.

Description

technical field [0001] The invention relates to the technical field of retrieval, in particular to an index updating system, method and device. Background technique [0002] The index file is used to record the corresponding relationship between the stored data files and the index, and the index points to the address of the corresponding data file, that is, the user can find the data file corresponding to the index through the index in the index file. When the data file stored in the database server is updated, the index corresponding to the data file in the index file also needs to be updated accordingly, so that when the user needs to search for the updated data file, he can find it through the updated index. [0003] At present, the update of the index needs to synchronize the data files on the database server to the client server through rsync (data synchronization), and then the index in the client server can be updated. Among them, the rsync update method needs to ins...
