What are some examples of partitioning in databases?
Partitioning in databases involves dividing a database into smaller, more manageable pieces. Examples include range partitioning, list partitioning, and hash partitioning.
Can you explain range partitioning with an example?
Sure! In range partitioning, data is divided based on a range of values. For instance, a sales database could be partitioned by year, where all sales from 2020 go into one partition, 2021 into another, and so on.
What about list partitioning?
List partitioning involves dividing data based on a predefined list of values. For example, a customer database could be partitioned by country, where each partition contains customers from a specific country.
How does hash partitioning work?
Hash partitioning uses a hash function to determine which partition a row belongs to. This method is useful for evenly distributing data across partitions.
