Major Description
Create 'spark_column_lineage' type and corresponding 'spark_process_column_lineage' relationship definition to add support of column-level lineage.
Column level lineage refers to lineage created between the input and output columns.
For example:
hive > create table employee_ctas as select id from employee;
For the above query, lineage is created from 'employee' to 'employee_ctas',
and also from 'employee.id' to 'employee_ctas.id'.
