A study on Time-series DBMS Application for EdgeX-based lightweight edge gateway

摘要

The EdgeX platform is an open source software project for edge gateways. Each function of edge gateway operates as a Docker container-based microservice, and at least 10 microservices operate simultaneously to perform a series of edge computing functions such as data collection, storage, analysis, and delivery. The load of each microservice is a very important issue because the lightweight edge gateway for relatively low-load data processing such as Smart Metering, Smart Home, and Smart Farm has low-end hardware capabilities for low price. In this paper, we describe the analysis results of the internal data storage of EdgeX, which has the most workload in the lightweight edge gateway. In addition, the test-bed application results with time-series DBMS are described and requirement issues are discussed.
