Abstract

The invention discloses a key value request parallel scheduling method and system, and the method comprises the steps of deploying a plurality of key value storage system instances, a plurality of request processing threads and a plurality of request queues, and carrying out the one-to-one binding of the instances, the request processing threads and the request queues through serial numbers; when key value requests sent by users are received, performing a request response step on each key value request, so that a plurality of concurrent user requests can be distributed to a plurality of request queues when the user requests exist; sending a plurality of parallel request processing threads to a plurality of key value storage system instances for execution, so that the IO parallelism degree is increased, and CPU multi-thread utilization is realized. Meanwhile, the keys managed by the key value storage system instances are mutually independent, resource competition and data synchronization among different key value storage system instances are avoided, efficient parallel execution is facilitated, and therefore the key value request processing speed is greatly increased.

Description

technical field [0001] The invention belongs to the field of computer storage, and more specifically relates to a key-value request parallel scheduling method and system. Background technique [0002] In recent years, with the development and application of cloud computing, big data, Internet of Things, artificial intelligence and other information technologies, the amount of data has shown explosive growth. How to effectively store data and provide efficient data access services has become an existing computer Important issues for storage systems. [0003] A key-value storage system is a common computer storage system, and its data storage unit is a key-value pair composed of two pieces of data, a key and a value. The key-value storage system is used to store key-value pair data in persistent storage devices, and provides the function of querying key-value pairs by pressing keys. The key-value storage request interface includes key-value requests such as storage (put), mo...
