Abstract

The invention is suitable for the technical field of the computer, and provides a strong consistency write-in method of data, and terminal equipment. The method comprises the following steps: determining a data block in which the data is to be written according to an IO request of writing the data into an object storage unit, redirecting a write operation to the local cache, and adding a write locking on the data block; writing the data in the data block, and removing the write locking after writing in the local cache; redirecting the write operation to the object storage unit, acquiring the timestamp of performing the latest write operation on the data block; if judging that the write operation on the data block is not overtime according to the timestamp, delaying the write operation; ifthe delay time achieves the preset time threshold, stopping delaying, and writing the data in the data block in the object storage unit according to the write operation, and guaranteeing the own strong consistency of the cache file through the write locking. The ordered operation of the multi-thread write object storage is ensured through write delay, so that an object storage service can be applied to an application with high data consistency requirement.

Description

technical field [0001] The invention belongs to the technical field of computers, and in particular relates to a method for writing data with strong consistency and a terminal device. Background technique [0002] With the rapid development of cloud computing technology and the advent of the era of big data, distributed object storage services featuring safety and reliability, flexible capacity expansion, ease of use, high performance, and low cost have been widely used in enterprise application systems. In order to enhance user experience, current object storage service providers implement high availability of the system and eventual consistency of data through asynchronous replication of multiple copies of data, ensuring the consistency perceived by users. However, for some enterprises that need to provide strong consistency (such as the medical field, financial field, etc.), relying solely on the data management mechanism of the cloud object storage service cannot meet th...
