1. Partitioning is just a change in the storage location of data and indexes in a table. A sub-table divides a table into multiple tables, which is a real supporting file for multiple sets of tables.

Partitions cannot break through the database level. No matter how you partition, these partitions should be under a database. Sub-tables can be assigned in the same library or in different libraries, breaking through the limitations of database performance.

2. Partition can only replace the function of horizontal table, not the function of vertical table.
