Notes on partitioning:

1. Not always true: When scrambling, we first create partitioned tables; then, insert values. This is the due to the restrictions of existing DBMS (e.g., Hive, Postgres) which prohibits creating a partitioned table as a result of a select query. For Hive, see https://cwiki.apache.org/confluence/display/Hive/LanguageManual+DDL#LanguageManualDDL-CreateTableCreate/Drop/TruncateTable
2. Postgres supports dynamic data insertions into appropriate partitions: https://www.postgresql.org/docs/10/static/sql-insert.html
3. Hive supports dynamic data insertions into appropriate partitions when options are turned on.
