Abstract

The invention provides a combined inquiring method oriented to an Hbase database and belongs to the technical field of data inquiry. The combined inquiring method includes creating an index table, namely defining Key and Value of the index table, wherein factors of the Key of the index table include N of M combining conditions, factors of the Value of the index table at least include Key corresponding to a main record table, the N is larger than or equal to 2 and smaller than or equal to the M, and the M is an integer larger than or equal to 2; creating indexes; retrieving data, namely performing main key inquiry in the index table according to first Key generated by extracting the N combining conditions, and performing main key inquiry in the main record table at least according to second Key defined by a factor of the Key of the main record table. The combined inquiring method is high in inquiring efficiency and especially suitable for data inquiry of a mass database.

Description

technical field [0001] The invention belongs to the technical field of data query, and relates to a compound query method oriented to an Hbase database. Background technique [0002] In recent years, the amount of data in enterprise IT systems has grown explosively, and it has become difficult for traditional databases to effectively manage data scales up to billions of records or even more. As an emerging data management technology, NoSQL database has achieved good scalability by simplifying the data model and weakening the data consistency requirements, providing an option for managing massive data. The HBase database is one of the NoSQL databases that are currently widely used. It is a distributed, column-oriented open source database with good scalability and is very suitable for massive data storage. [0003] Usually, each record in the HBase database is a simple byte array with a relatively fixed Key-Value (primary key-key value) structure, that is, each record has a ...
