Cloud Data

A new cloud service provider plans to launch its services in the near future. The database cluster for keeping user data will consist of database nodes with each node placed in a different region.

Users can choose the regional node their data will reside on. User data is kept in a table along with the region id. The region id and the region name are kept in another table which is redundant on every region node.

Select all answers that are true for the given scenario.

(Select all acceptable answers.)

Vertically partitioning the region id column of the user data table will allow database sharding with shards residing on different nodes.

Horizontally partitioning the user data table based on values in the region id column will allow database sharding with shards residing on different nodes.

To create partitions, each partition should be created for a range of region ids from the user data table.

To create partitions, each partition should be created for a unique region id from the user data table.

Fetching the region name with user data will require join queries across different regional partitions.
