Partitioning:?

Short answer: Partitioning is the process of dividing a single table into smaller, more manageable pieces (partitions). This can be done either horizontally or vertically. Horizontal Partitioning: Data is divided based on rows (e.g., splitting a sales table by date range). Vertical Partitioning: Data is divided based on columns (e.g., splitting a user table into two: one for personal information and the other for preferences).

Example code

A sales table might be partitioned by year (2019, 2020, etc.), where each partition is stored in a different location or server.
