Embodiment Construction

[0019] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

[0020] Such as figure 1 Shown is a working flow chart of a database cluster data distribution method of the present invention, including:

[0021] Step S101, including: regularly detecting the data storage conditions of all database sets in the database cluster, acquiring the database sets whose data storage capacity exceeds the threshold as the database sets to be divided, and setting the database sets to be divided into the split state;

[0022] Step S102, including: pre-segmenting the database set to be divided according to the preset segmentation rules, obtaining the number of new sets after division, creating a transfer database set with the new set number, and determining a plurality of transfer databases corresponding to the database set to be divided according to the segmentation rule collection, transferring the data in the ...

Abstract

The invention discloses a database cluster data distribution method and system. The method comprises: regularly detecting data storage states of all database sets in a database cluster, obtaining the database set with the data storage quantity exceeding a threshold value as a to-be-segmented database set, and setting the to-be-segmented database set to be in a segmentation state; transferring data in the to-be-segmented database set to a transfer database set; in response to a data write-in request of a client, if the current database set is in the segmentation state, obtaining the transfer database set corresponding to the current database set according to a segmentation rule, and writing data written by the client into the current database set and the transfer database set; and after the data in the to-be-segmented database set is transferred to the transfer database set, uninstalling the to-be-segmented database set from the database cluster. According to the database cluster data distribution method and system, the data is uniformly distributed and the influence on the data written by the client in segmentation and transfer processes is avoided at the same time.

Description

technical field [0001] The invention relates to the technical field related to databases, in particular to a database cluster data distribution method and system. Background technique [0002] With the diversification of query conditions and higher query performance requirements, many businesses now use database clusters, such as SolrCloud, as query engines. Solr is an independent enterprise-level search application server, similar to a database, which provides an API interface similar to Web-service. Users can submit XML files in a certain format to the search engine server through http requests to generate indexes; they can also submit search requests through Http Get operations and get returned results in XML format. SolrCloud is a set of cluster deployment solutions for several Solr applications. [0003] However, as the amount of data grows, the data needs to be stored in shards. The sharding mechanism provided by the database cluster cannot well meet business needs. ...
