Abstract

The invention provides a RocksDB performance improvement method and system and a storage medium, and the method comprises the steps: generating a write operation class in response to RocksDB, putting the write operation class into a write queue, and querying whether there are preset n write operation class leading queues in the write queue, wherein n is greater than 1; in response to the fact that no write operation class leader exists in the write queue and the total number m of write operation classes in the write queue is larger than n, selecting n write operation classes from the write queue to serve as the write operation class leader, and merging the other write operation classes in the write queue based on the total number m so that the other write operation classes can be merged into the n write operation class leader; and respectively submitting the n write operation class leaders subjected to merging processing to the corresponding n pre-write logs. According to the invention, the log submission mode of the RocksDB is set from the original serial log submission mode to the parallel log submission mode, the performance of the RocksDB under high voltage is improved, and the I / O time delay of a high-speed equipment storage system is reduced.

Description

technical field [0001] The invention relates to the technical field of distributed storage, in particular to a RocksDB performance improvement method, system and storage medium. Background technique [0002] Distributed storage systems have been widely used in fields such as cloud computing and big data analysis. Distributed storage systems with different hardware specifications will appear in different scenarios and requirements, generally including: slow device storage, hybrid slow and high-speed device storage, and High speed device storage. How to make full use of the performance of high-speed devices in high-speed device storage is a problem that current distributed storage systems are eager to solve. The performance bottleneck of the distributed storage system is mainly concentrated in the I / O (data input / output) processing of the local storage engine. The I / O processing of the local storage engine is divided into metadata and data. Some distributed storage systems u...
