Abstract

The invention provides a service data management method based on HDFS and a terminal device. The method includes; creating a first folder in the HDFS; storing the first service data corresponding to the service into the first folder, wherein the identification part of the service data comprises a first identification and a second identification, the first identification is a globally unique identification of the service in the HDFS, and the second identification is a globally unique identification of the service data in the HDFS; If the first service data is correct, a unique mapping relationship between the second identifier and the valid flag in the first service data is created in the preset form, and if the first service data is incorrect, a unique mapping relationship between the second identifier and the invalid flag in the first service data is created in the preset form; According to the identification part of the service data in the first folder and the preset form, the service data for running the service is read in the HDFS. Through the identification part of the business data and the preset form, the correct business data can be read, and the system operation error caused by the wrong business data can be avoided.

Description

technical field [0001] The invention belongs to the technical field of computers, and in particular relates to an HDFS-based business data management method and terminal equipment. Background technique [0002] With the rapid development of IT technology and the deepening of informatization, the amount of data generated continues to increase. In the era of big data, the growth rate of data volume will exceed the growth rate of storage data medium capacity, that is, the cost of storage will continue to rise, and the cost of storage media will continue to increase. Faced with this huge amount of data generation, traditional data management systems The data processing technology has been greatly challenged. How to store these data more efficiently and stably has become a research hotspot in many fields such as data processing. [0003] At present, people often use HDFS (Hadoop Distributed File System, Hadoop Distributed File System) to store these data. HDFS is a reliable fil...
