How to Automatically Migrate All Tables From a Database to Hadoop With No Coding
A company wants to know when new tables are added to a JDBC source (say an RDBMS). Using the ListDatabaseTables processor, we can get a list of tables (also views, system tables, and other database objects), but for our purposes, we want tables with data. I have used the ngdbc.jar from SAP HANA to connect and query tables with ease.
For today's example, I am connecting to MySQL, as I have a MySQL database available for use and modification.
