Index establishing and using method and device

Abstract

The invention relates to the technical field of data processing, in particular to an index establishing and using method and device. The method comprises the following steps: for each service, generating a corresponding service index corresponding to a current time granularity, the time granularity being a period for generating a corresponding service index for a certain service; and respectivelyexecuting the following operations on each service in each service: for each service index corresponding to one service, configuring at least one index alias, one index alias being used for associating at least one service index generated by the corresponding service in a specified time dimension. According to the method, a single service index does not need to bear the service data correspondingto one service, so that the indexing speed is increased, the required service index can be inquired through the corresponding index alias configured for the index corresponding to one service, decoupling between the service and the index is realized, and the coding difficulty of the service code is reduced.

Description

technical field [0001] The present application relates to the technical field of data processing, in particular to a method and device for establishing and using an index. Background technique [0002] With the rapid development of Internet technology, the amount of resources and business volume on the Internet is increasing rapidly. The search server (ElasticSearch, ES) based on Lucene provides a full-text search engine with distributed multi-user capabilities. ElasticSearch is developed in Java and released as open source under the terms of the Apache license. In related technologies, the indexing method generally adopted is to create a corresponding ES index for a service. However, after the index is created, the key attributes of the index cannot be changed, such as the number of index shards (shards). Then, as the business goes online, the accumulated business data will increase. The pressure is also increasing, which will lead to slow indexing speed, which will affec...
