We had some users which their info. was stored in Oracle db. the tables include some Joins, too.

Now, I want to build a new project, using Cassandra which will use the information of previews users, too.

The data modeling is using Cassandra principles. But the question is that:
How I can move or migrate the needed hole heavy data from Oracle to new non-relational database? (what steps)

Usually, you should use the "Cassandra Bulk Loader" tool. And this link talks many considerations about "MySQL to Cassandra Migrations", which should be similar to migrating from Oracle.
