Abstract

The invention discloses a thread awakening method and device, a data processing method and device of a distributed database, a computer storage medium and electronic equipment. The awakening method comprises the steps of obtaining a waiting identifier of a current write-in thread corresponding to a pre-write operation according to a success result of the pre-write operation for an access operationrequest in a current execution thread; wherein the current write-in thread corresponds to the current execution thread; determining a wake-up range of a wake-up thread wake-up execution thread according to the waiting identifier of the current write-in thread; awakening the execution thread according to the awakening range; therefore, the problem of poor system performance caused by invalid awakening is avoided, and the throughput of the system is improved; and the wake-up process is completed based on the version number, so that the wake-up method is suitable for a blocking-wake-up mechanismin various scenes, and has certain universality.

Description

technical field [0001] The present application relates to the field of computer application technology, in particular to a thread wake-up method and device, and a distributed database data processing method and device; the present application also relates to a computer storage medium and electronic equipment. Background technique [0002] With the continuous and rapid expansion of data volume, the processing performance of traditional databases on big data can no longer meet the needs, and unstructured distributed databases have emerged as the times require. [0003] When an unstructured distributed database requests read and write operations, in order to ensure the stability of the data, it is necessary to pre-write the data requested by the operation through the WAL (Write-Ahead-Log) mechanism in advance, so as to avoid data loss in abnormal situations. The problem of loss, specifically, when the unstructured distributed database reads and writes data, it uses the Handler ...
