In general Java projects and now particularly hot data analysis projects, the use of database and database resource pool connection is a commonplace. Today it's a simple way to sort through the process: We look at the code in order of dispatch: Comment, we are from the spark data analysis to do demo expansion: First, suppose that the read-write
