What are some examples of partition keys in databases?
Partition keys are used to distribute data across different partitions in a database. For example, in a user database, a common partition key could be 'user_id'.
Can you give me more examples of partition keys?
Sure! Other examples include 'date' for time-series data, 'region' for geographical data, and 'product_id' for e-commerce databases.
How do partition keys affect performance?
Partition keys can significantly improve performance by allowing parallel processing and reducing the amount of data scanned during queries.
What happens if I choose a bad partition key?
Choosing a bad partition key can lead to uneven data distribution, causing some partitions to be overloaded while others are underutilized, which can degrade performance.
