Embodiment Construction

[0060] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art based on the present application belong to the protection scope of the present invention.

[0061] In the related technology, each object block to be deleted is queried and deleted one by one in turn. Therefore, when the number of object blocks to be deleted is large, it takes a long time to delete the object blocks to be deleted. The deletion efficiency is low.

[0062] In order to solve the above technical problems, an embodiment of the present invention provides a data deletion system.

[0063] Before describing a data deletion system provided b...

Abstract

The embodiment of the invention provides a data deletion system, method and device, which relate to the technical field of distributed storage. The system is applied to a Ceph system, and the Ceph system comprises a client and at least one piece of block equipment; the client is used for determining a target identifier of a to-be-deleted object block; a corresponding relationship between preset block equipment and the object block identifier is traversed, target block equipment in which a target object block with the target identifier is stored is determined, and the target object block is stored to a specified queue of the target block equipment; a data deletion request for indicating the target block equipment to delete the target object block is sent to the target block equipment; each piece of block equipment is used for obtaining a target identifier when receiving a data deletion request sent by a client; a specified thread which is preset in the thread pool and is used for executing object block deletion operation is awakened; and the target object block in the specified queue of the block equipment isdeleted by using the specified thread. Compared with the prior art, by applying the scheme provided by the embodiment of the invention, the deletion efficiency of the object block can be improved.

Description

technical field [0001] The invention relates to the technical field of distributed storage, in particular to a data deletion system, method and device. Background technique [0002] At present, with the continuous development of distributed storage technology, the Ceph system (free software distributed file system) has been adopted by more and more technicians due to its features such as scalability to PB capacity, support for multiple workloads, and high reliability. concern. Among them, PB is the data unit of storage capacity, 1PB=1027TB. [0003] Wherein, the Ceph system includes: a client (RBD CLIENT) and at least one block device (OSD, ObjectStorage Device); wherein, each block device has functions such as storing data, copying data, deleting data, and restoring data, and each block The data in the device is stored in the form of object blocks. Correspondingly, the client can be used to complete the initial configuration of Ceph according to the instructions issued b...
