How Does a Spark Job Access a MySQL Database?
You can use DLI Spark jobs to access data in the MySQL database using either of the following methods:
- Solution 1: Buy a queue, create an enhanced datasource connection, and read data from the MySQL database through a datasource table. You need to write Java or Scala code to implement this solution.
- Solution 2: Use CDM to import data from the MySQL database to an OBS bucket, and then use a Spark job to read data from the OBS bucket. If you already have a CDM cluster, this solution is simpler than solution 1 and does not involve any other database.
