Problems solved by technology

The existing technology uses the distributed search engine ElasticSearch to perform distributed search, and then merges the search result data to obtain the final data. This indexing scheme will have very low indexing efficiency before facing massive data of more than 100 terabytes , it is difficult to meet the needs of indexing; there is an urgent need for a solution that can improve the efficiency of data indexing for massive data of more than 100 terabytes

Abstract

The invention discloses an ElasticSearch-based data indexing method and a device, computer equipment and a storage medium. The method comprises the steps: setting a main fragment based on a distributed search engine ElasticSearch, and writing data into the main fragment; aiming at the data of each main fragment, respectively creating an index task, importing the corresponding index fragment into the main fragment according to the type of the index task, and creating an index; if a data query request instruction is detected, performing index query on the index fragments through each node serverto obtain the index data volume of each node server; combining the index data volume of each node server to obtain a total index data volume; and if it is detected that the total index data volume exceeds a preset numerical value, indexing in a preset mode. The invention also relates to the blockchain technology. Index data is stored in the blockchain. According to the method, the data indexing efficiency is improved for mass data of hundreds of T or above.

Description

technical field [0001] The present application relates to the technical field of data processing, in particular to an ElasticSearch-based data indexing method, device, computer equipment and storage medium. Background technique [0002] In the current age of big data, there are many data warehouses used to store massive data, and the distributed search engine ElasticSearch (search engine, ES) is one of them. The distributed search engine ElasticSearch is an open source, distributed, Restful search server based on Lucene, which is generally used in cloud computing. It can easily enable large amounts of data to be searched, analyzed and explored. Making full use of the horizontal scalability of the distributed search engine ElasticSearch can make data more valuable in the production environment. [0003] For the indexing scheme of the distributed search engine ElasticSearch for massive data of more than 100 terabytes, due to the huge amount of data, if there is no correspond...
