Abstract

The invention provides a query request processing method and device. The query request processing method comprises the following steps: receiving a thread which applies for entering a storage engine, wherein the thread is used for processing a current statement; after a situation that the thread applies for entering the storage engine is determined, distributing the current frequency of access permit for the thread; and distributing a first access permit numerical value for the thread, wherein the first access permit numerical number is inversely proportional to the current frequency. The method can shorten query response time based on a concurrency control strategy and improve the query efficiency of the storage engine.

Description

technical field [0001] The present application relates to the technical field of data processing, and in particular to a query request processing method and device. Background technique [0002] When online applications use databases, for OLTP (On-Line Transaction Processing) type applications, the result set of the query is generally small, that is, it needs only a few interactions with the storage engine to complete A query request, this type of query can be called a small query; however, online applications also have queries with large result sets or queries that do not use indexes correctly. The latter two queries require more interactions with the storage engine to Complete a query, this type of query can be called a large query. In related technologies, large queries have the same priority as small queries, resulting in slow query response speed and low query efficiency under the concurrency control strategy of the database storage engine.
