The objective of this exercise is to demonstrate how the migration of data from CSV to Oracle to Cassandra can change the required underlying storage volume of the data. How do data volumes change between pure ASCII source records versus records stored in tables in an Oracle database versus records stored in tables in a

The objective of this exercise is to demonstrate how to migrate data from Oracle to DataStax Cassandra. I’ll be using the DataFrame capability introduced in Apache Spark 1.3 to load data from tables in an Oracle database (12c) via Oracle’s JDBC thin driver, to generate a result set, joining tables where necessary. The data will
