The scheme is difficult to expand and has little concurrent ability, so it is not suitable to deal with semi-structured, Unstructured data. Then along came distributed technologies such as Hadoop, which had the advantage of using inexpensive machines to store and process data. But HADOOP was designed to distribute data equally among the nodes in the cluster for storage and processing, ignoring the differences in the storage and computing capabilities of the cluster nodes themselves, and the performance of individual nodes even affects the performance of the collation system, and it is master-slave node processing data, there are data can tamper, system terminal is too single and so on. The contribution of this paper lies in the overall structure and technical route of the new rural cooperative medical system, and the optimization method of data flow of heterogeneous nodes, which can effectively save the scale and cost of the cluster, with the help of blockchain technology to ensure the security and credibility of data, optimize the front-end cluster service architecture, support multi-channel and high-concurrent key information push mode, has a very good promotion.</span>

Highlights

  • The New Rural Cooperative Medical System [1,2] is supported and guided by the government, and farmers actively participate in it

  • The new rural cooperative medical system has been upgraded from a traditional relational database to a Hadoop platform

  • This paper proposes an improved HDFS data layout scheme, which improves the overall performance of Hadoop in a heterogeneous environment, can save the scale and energy consumption of the new rural cooperative system cluster, give full play to the maximum advantages of the cluster, increase the operating speed of the cluster, and use the least cost in exchange for the greatest benefit [14,15]

Summary

Introduction

The New Rural Cooperative Medical System [1,2] (hereinafter referred to as the New Rural Cooperative Medical System) is supported and guided by the government, and farmers actively participate in it. The current system has problems such as inappropriate cluster scale, high construction cost, easy tampering of medical data, delayed push of end-user data, poor pertinence of the system, and poor concurrent performance. 2. To improve system security and data credibility, high-level use of district block chain technology ensures that the new rural cooperative medical system critical data credible, cannot be tampered with, to ensure that farmers, government, healthcare system benefits are not infringed. 3. Optimize the concurrent performance of the system, improve the front-end cluster service architecture, expand the terminal form, and push the associated data of different roles in time through data mining and other technologies to improve the user experience of the new rural cooperative system
