$14.$ Data Partitioning

In data partitioning, a large dataset is divided into smaller pieces. Which of the following are true?

Pick ONE OR MORE options

There is a users database that stores many attributes for each user. It is partitioned so that one partition gets names and emails, another partition receives avatars and addresses and so on$.$ This is called vertical partitioning.

If you have a collection of users with a lot of attributes and you decide to partition the data so that each partition receives just a subset of users with all their attributes, this is called horizontal partitioning.

Vertical and horizontal partitioning cannot be combined.

Round$-$robin partitioning is a partitioning strategy that is especially good when the number of partitions changes over time.
