Problems solved by technology

[0005] In MVBT technology, each memory page includes a large number of memory elements. In order to read the target memory element from a large number of memory elements, it is necessary to traverse from the first memory element until the target memory element is traversed. The above method needs to traverse A large number of memory elements will consume a lot of time and affect th

Abstract

A data processing method and apparatus are provided. The method includes: determining a first memory page corresponding to a first Key carried by the read operation command after receiving the read operation command; Obtaining a first position offset represented by an element of the first array from a first sorted array corresponding to the first memory page, and determining a first memory elementin the first memory page corresponding to the first position offset; Judging whether the first Key and the life cycle corresponding to the first Key match the second Key and the life cycle recorded in the first memory element; If so, a data portion corresponding to the first Key is read from the first memory element. Through the technical proposal of the application, the traversal times can be reduced, the target memory element can be quickly read from a large number of memory elements, a large amount of time can be saved, and the page access speed can be improved.

Description

technical field [0001] The present application relates to the field of storage technologies, and in particular to a data processing method and device. Background technique [0002] Key-Value (key-value) database is currently the most widely used database, which can store, read and manage data through unique identification. The storage structure can be tree structure or hash structure, and can include LMDB (Lighting Memory -mapped Data Base, memory-mapped database), etc. [0003] The Key-Value database uses COW (Copy-On-Write, copy-on-write) technology to provide concurrency protection, improve the concurrency of data storage, and achieve high data read and write performance. COW technology refers to: For each modification operation, copy the memory page involved in the modification, and do not modify the original memory page, and the modification operation is concentrated on the copied new memory page. Since the original memory page has not been modified, read transactions...
