Title:
OBJECT STORAGE METHOD AND APPARATUS BASED ON DISTRIBUTED DATABASE
Document Type and Number:
WIPO Patent Application WO/2023/197404
Kind Code:
A1
Abstract:
An object storage method and apparatus based on a distributed database, which method and apparatus are used in a distributed database system, wherein a disk and a memory are shared between nodes. The method comprises: when the current node receives an internal request for index writing, writing a behavior log of an API of the current node into a disk and a memory of the current node, and then writing into a FIFO queue in the memory of the current node an index corresponding to the index writing (S101); writing all indexes in the queue into the disk either periodically or when the queue is full (S102); and when an internal request for index reading is received, reading from the disk an index corresponding to the index reading and returning the index (S103). Firstly, indexes are written into a memory which serves as a buffer pool, and then, the indexes are written into a disk at a suitable time, and a behavior log is recorded in advance. In this way, a memory and a disk are used together and complement each other, such that the writing rate can be increased, and the high-concurrency reading and writing characteristics can be met. Moreover, by means of a memory and disk sharing mechanism and recording a behavior log in both a memory and a disk, the high availability of index data is ensured.
