List Partitioning Implementation

Welcome! In this lesson, we'll dive into List Partitioning, a powerful way to organize your data in PostgreSQL.

List partitioning divides a table based on discrete values in a specified column. Think of it as categorizing your data into distinct groups.

You might recall Range Partitioning from a previous lesson, which divides data based on a *range* of values (e.g., dates, IDs).

List partitioning is different: it uses specific, distinct values. For example, you could partition by country_code ('US', 'CA', 'MX') or order_status ('PENDING', 'SHIPPED', 'CANCELLED').
