【摘要】：在物联网环境中,大量的传感器产生了海量的数据.这些数据一般需要立刻保存到数据库中,以实现分析与应用.大量传感器数据写入到数据库中,会在存储系统中产生严重的小数据同步写性能瓶颈,严重影响数据库系统性能.本文设计了一种物联网数据库高性能廉价闪存缓冲队列——IFCQD(Inexpensive Flash Cache Queue for Database).IFCQD充分利用了USB 3.0接口与FLASH闪存的高速特性,在保证数据同步写入存储器,不会意外丢失的基础上,可以显著地优化大量数据写入到数据库中的性能.针对FLASH闪存的特性,本文还使用了双重索引法来提高闪存缓冲机制的性能.实验表明,IFCQD机制可以基于廉价的闪存,在物联网应用环境中显著地提高数据采集系统的性能.
[Abstract]:In the Internet of things environment, a large number of sensors produce a great deal of data.These data generally need to be stored in the database immediately to achieve analysis and application.A large number of sensor data are written to the database, which will cause a serious bottleneck of the performance of the small data synchronous write in the storage system, and seriously affect the performance of the database system.In this paper, we design a kind of high performance and low cost flash buffer queue for Internet of things database. IFCQDX Flash Cache Queue for Database).IFCQD makes full use of the high speed characteristic of USB 3.0 interface and FLASH flash memory, on the basis of ensuring that the data is written into memory synchronously and without accidental loss.You can significantly optimize the performance of large amounts of data written to the database.According to the characteristics of FLASH flash memory, this paper also uses double index method to improve the performance of flash buffer mechanism.Experiments show that the IFCQD mechanism can significantly improve the performance of data acquisition system in the Internet of things application environment based on cheap flash memory.
