Key-value storage systems are widely used in a variety of internet services, but existing key-value storage systems are often designed and implemented in user-state space because of frequent pattern switching and context switching, resulting in inefficient access interfaces, transaction processing, high concurrency, Especially in the low latency data storage requirements. To solve this problem, a kernel-state Key-value storage System is presented--kstore: providing kernel-space indexing and memory allocation mechanism, and on the basis of which, through the remote interface based on kernel socket and the local interface based on file system, the low latency of kstore is guaranteed. , the concurrency of Kstore is ensured by the concurrent processing mechanism based on kernel multithreading. The experimental results show that compared with memcached, Kstore has a significant advantage in real-time and concurrency.
