Abstract

The invention provides a hardware database query method and device and a database system query method and device. The hardware database query method comprises the steps of receiving query request information; according to the query request information, executing one or more instructions in a hardware database processor instruction set to obtain a query execution result; and outputting the query execution result, wherein the query request information comprises information needing to be transmitted in when the one or more instructions are executed; the hardware database processor instruction set comprises a data sequence selection instruction, a data element condition selection instruction, a data element reference selection instruction, a data sequence merging connection instruction, a data table division instruction, a data sequence aggregation instruction, an isomorphic data table splicing instruction and a data table sorting instruction. Through the scheme, the database query processing speed can be increased.

Description

technical field [0001] The invention relates to the technical field of databases, in particular to a hardware database query method, a database system query method and a device. Background technique [0002] With the increase of the amount of data, the delay of database access is getting bigger and bigger. Many tasks that were once easy to accomplish with traditional methods on small data are now very difficult on big data. At present, the fastest SSD storage can achieve a read speed of 12GB / s, but even at this speed, if the database has a size of 15TB, it still takes 33 hours to complete a query in a complete retrieval manner. In order to speed up the query speed of the database, the method of designing a special processor (hardware database) can be considered to improve the performance of the database. However, the instructions of traditional databases cannot be applied to special-purpose processors, and even if they are partially applicable, it is difficult for special-p...
